INCOME LIMITS and RULES Each of the three MSP programs has different income eligibility requirements and provides different benefits. The income limits are tied to the Federal Poverty Level (FPL). 2021 FPL levels were released by NYS bronchitis ventolin DOH in GIS 21 MA/06 - 2021 Federal Poverty Levels Attachment II NOTE.

There is usually a lag in time of several weeks, or even months, from January 1st of each year until the new FPLs are release, and then before the new MSP income limits are officially implemented. During this lag period, local Medicaid offices should continue to use the previous year's FPLs AND count the person's Social Security benefit amount from the previous year - do NOT factor in the Social Security COLA (cost of living adjustment). Once the updated guidelines are released, districts will use the bronchitis ventolin new FPLs and go ahead and factor in any COLA. See 2021 Fact Sheet on MSP in NYS by Medicare Rights Center ENGLISH SPANISH Income is determined by the same methodology as is used for determining in eligibility for SSI The rules for counting income for SSI-related (Aged 65+, Blind, or Disabled) Medicaid recipients, borrowed from the SSI program, apply to the MSP program, except for the new rules about counting household size for married couples. N.Y.

Soc. Serv. L. 367-a(3)(c)(2), NYS DOH 2000-ADM-7, 89-ADM-7 p.7. Gross income is counted, although there are certain types of income that are disregarded.

The most common income disregards, also known as deductions, include. (a) The first $20 of your &. Your spouse's monthly income, earned or unearned ($20 per couple max). (b) SSI EARNED INCOME DISREGARDS. * The first $65 of monthly wages of you and your spouse, * One-half of the remaining monthly wages (after the $65 is deducted).

* Other work incentives including PASS plans, impairment related work expenses (IRWEs), blind work expenses, etc. For information on these deductions, see The Medicaid Buy-In for Working People with Disabilities (MBI-WPD) and other guides in this article -- though written for the MBI-WPD, the work incentives apply to all Medicaid programs, including MSP, for people age 65+, disabled or blind. (c) monthly cost of any health insurance premiums but NOT the Part B premium, since Medicaid will now pay this premium (may deduct Medigap supplemental policies, vision, dental, or long term care insurance premiums, and the Part D premium but only to the extent the premium exceeds the Extra Help benchmark amount) (d) Food stamps not counted. You can get a more comprehensive listing of the SSI-related income disregards on the Medicaid income disregards chart. As for all benefit programs based on financial need, it is usually advantageous to be considered a larger household, because the income limit is higher.

The above chart shows that Households of TWO have a higher income limit than households of ONE. The MSP programs use the same rules as Medicaid does for the Disabled, Aged and Blind (DAB) which are borrowed from the SSI program for Medicaid recipients in the “SSI-related category.” Under these rules, a household can be only ONE or TWO. 18 NYCRR 360-4.2. See DAB Household Size Chart. Married persons can sometimes be ONE or TWO depending on arcane rules, which can force a Medicare beneficiary to be limited to the income limit for ONE person even though his spouse who is under 65 and not disabled has no income, and is supported by the client applying for an MSP.

EXAMPLE. Bob's Social Security is $1300/month. He is age 67 and has Medicare. His wife, Nancy, is age 62 and is not disabled and does not work. Under the old rule, Bob was not eligible for an MSP because his income was above the Income limit for One, even though it was well under the Couple limit.

In 2010, NYS DOH modified its rules so that all married individuals will be considered a household size of TWO. DOH GIS 10 MA 10 Medicare Savings Program Household Size, June 4, 2010. This rule for household size is an exception to the rule applying SSI budgeting rules to the MSP program. Under these rules, Bob is now eligible for an MSP. When is One Better than Two?.

Of course, there may be couples where the non-applying spouse's income is too high, and disqualifies the applying spouse from an MSP. In such cases, "spousal refusal" may be used SSL 366.3(a). (Link is to NYC HRA form, can be adapted for other counties). In NYC, if you have a Medicaid case with HRA, instead of submitting an MSP application, you only need to complete and submit MAP-751W (check off "Medicare Savings Program Evaluation") and fax to (917) 639-0837. (The MAP-751W is also posted in languages other than English in this link.

(Updated 4/14/2021.)) 3. The Three Medicare Savings Programs - what are they and how are they different?. 1. Qualified Medicare Beneficiary (QMB). The QMB program provides the most comprehensive benefits.

Available to those with incomes at or below 100% of the Federal Poverty Level (FPL), the QMB program covers virtually all Medicare cost-sharing obligations. Part B premiums, Part A premiums, if there are any, and any and all deductibles and co-insurance. QMB coverage is not retroactive. The program’s benefits will begin the month after the month in which your client is found eligible. ** See special rules about cost-sharing for QMBs below - updated with new CMS directive issued January 2012 ** See NYC HRA QMB Recertification form ** Even if you do not have Part A automatically, because you did not have enough wages, you may be able to enroll in the Part A Buy-In Program, in which people eligible for QMB who do not otherwise have Medicare Part A may enroll, with Medicaid paying the Part A premium (Materials by the Medicare Rights Center).

2. Specifiedl Low-Income Medicare Beneficiary (SLMB). For those with incomes between 100% and 120% FPL, the SLMB program will cover Part B premiums only. SLMB is retroactive, however, providing coverage for three months prior to the month of application, as long as your client was eligible during those months. 3.

Qualified Individual (QI-1). For those with incomes between 120% and 135% FPL, and not receiving Medicaid, the QI-1 program will cover Medicare Part B premiums only. QI-1 is also retroactive, providing coverage for three months prior to the month of application, as long as your client was eligible during those months. However, QI-1 retroactive coverage can only be provided within the current calendar year. (GIS 07 MA 027) So if you apply in January, you get no retroactive coverage.

Q-I-1 recipients would be eligible for Medicaid with a spend-down, but if they want the Part B premium paid, they must choose between enrolling in QI-1 or Medicaid. They cannot be in both. It is their choice. DOH MRG p. 19.

In contrast, one may receive Medicaid and either QMB or SLIMB. 4. Four Special Benefits of MSPs (in addition to NO ASSET TEST). Benefit 1. Back Door to Medicare Part D "Extra Help" or Low Income Subsidy -- All MSP recipients are automatically enrolled in Extra Help, the subsidy that makes Part D affordable.

They have no Part D deductible or doughnut hole, the premium is subsidized, and they pay very low copayments. Once they are enrolled in Extra Help by virtue of enrollment in an MSP, they retain Extra Help for the entire calendar year, even if they lose MSP eligibility during that year. The "Full" Extra Help subsidy has the same income limit as QI-1 - 135% FPL. However, many people may be eligible for QI-1 but not Extra Help because QI-1 and the other MSPs have no asset limit. People applying to the Social Security Administration for Extra Help might be rejected for this reason.

Recent (2009-10) changes to federal law called "MIPPA" requires the Social Security Administration (SSA) to share eligibility data with NYSDOH on all persons who apply for Extra Help/ the Low Income Subsidy. Data sent to NYSDOH from SSA will enable NYSDOH to open MSP cases on many clients. The effective date of the MSP application must be the same date as the Extra Help application. Signatures will not be required from clients. In cases where the SSA data is incomplete, NYSDOH will forward what is collected to the local district for completion of an MSP application.

The State implementing procedures are in DOH 2010 ADM-03. Also see CMS "Dear State Medicaid Director" letter dated Feb. 18, 2010 Benefit 2. MSPs Automatically Waive Late Enrollment Penalties for Part B Generally one must enroll in Part B within the strict enrollment periods after turning age 65 or after 24 months of Social Security Disability. An exception is if you or your spouse are still working and insured under an employer sponsored group health plan, or if you have End Stage Renal Disease, and other factors, see this from Medicare Rights Center.

If you fail to enroll within those short periods, you might have to pay higher Part B premiums for life as a Late Enrollment Penalty (LEP). Also, you may only enroll in Part B during the Annual Enrollment Period from January 1 - March 31st each year, with Part B not effective until the following July. Enrollment in an MSP automatically eliminates such penalties... For life.. Even if one later ceases to be eligible for the MSP.

AND enrolling in an MSP will automatically result in becoming enrolled in Part B if you didn't already have it and only had Part A. See Medicare Rights Center flyer. Benefit 3. No Medicaid Lien on Estate to Recover MSP Benefits Paid Generally speaking, states may place liens on the Estates of deceased Medicaid recipients to recover the cost of Medicaid services that were provided after the recipient reached the age of 55. Since 2002, states have not been allowed to recover the cost of Medicare premiums paid under MSPs.

In 2010, Congress expanded protection for MSP benefits. Beginning on January 1, 2010, states may not place liens on the Estates of Medicaid recipients who died after January 1, 2010 to recover costs for co-insurance paid under the QMB MSP program for services rendered after January 1, 2010. The federal government made this change in order to eliminate barriers to enrollment in MSPs. See NYS DOH GIS 10-MA-008 - Medicare Savings Program Changes in Estate Recovery The GIS clarifies that a client who receives both QMB and full Medicaid is exempt from estate recovery for these Medicare cost-sharing expenses. Benefit 4.

SNAP (Food Stamp) benefits not reduced despite increased income from MSP - at least temporarily Many people receive both SNAP (Food Stamp) benefits and MSP. Income for purposes of SNAP/Food Stamps is reduced by a deduction for medical expenses, which includes payment of the Part B premium. Since approval for an MSP means that the client no longer pays for the Part B premium, his/her SNAP/Food Stamps income goes up, so their SNAP/Food Stamps go down. Here are some protections. Do these individuals have to report to their SNAP worker that their out of pocket medical costs have decreased?.

And will the household see a reduction in their SNAP benefits, since the decrease in medical expenses will increase their countable income?. The good news is that MSP households do NOT have to report the decrease in their medical expenses to the SNAP/Food Stamp office until their next SNAP/Food Stamp recertification. Even if they do report the change, or the local district finds out because the same worker is handling both the MSP and SNAP case, there should be no reduction in the household’s benefit until the next recertification. New York’s SNAP policy per administrative directive 02 ADM-07 is to “freeze” the deduction for medical expenses between certification periods. Increases in medical expenses can be budgeted at the household’s request, but NYS never decreases a household’s medical expense deduction until the next recertification.

Most elderly and disabled households have 24-month SNAP certification periods. Eventually, though, the decrease in medical expenses will need to be reported when the household recertifies for SNAP, and the household should expect to see a decrease in their monthly SNAP benefit. It is really important to stress that the loss in SNAP benefits is NOT dollar for dollar. A $100 decrease in out of pocket medical expenses would translate roughly into a $30 drop in SNAP benefits. See more info on SNAP/Food Stamp benefits by the Empire Justice Center, and on the State OTDA website.

Some clients will be automatically enrolled in an MSP by the New York State Department of Health (NYSDOH) shortly after attaining eligibility for Medicare. Others need to apply. The 2010 "MIPPA" law introduced some improvements to increase MSP enrollment. See 3rd bullet below. Also, some people who had Medicaid through the Affordable Care Act before they became eligible for Medicare have special procedures to have their Part B premium paid before they enroll in an MSP.

See below. WHO IS AUTOMATICALLY ENROLLED IN AN MSP. Clients receiving even $1.00 of Supplemental Security Income should be automatically enrolled into a Medicare Savings Program (most often QMB) under New York State’s Medicare Savings Program Buy-in Agreement with the federal government once they become eligible for Medicare. They should receive Medicare Parts A and B. Clients who are already eligible for Medicare when they apply for Medicaid should be automatically assessed for MSP eligibility when they apply for Medicaid.

(NYS DOH 2000-ADM-7 and GIS 05 MA 033). Clients who apply to the Social Security Administration for Extra Help, but are rejected, should be contacted &. Enrolled into an MSP by the Medicaid program directly under new MIPPA procedures that require data sharing. Strategy TIP. Since the Extra Help filing date will be assigned to the MSP application, it may help the client to apply online for Extra Help with the SSA, even knowing that this application will be rejected because of excess assets or other reason.

SSA processes these requests quickly, and it will be routed to the State for MSP processing. Since MSP applications take a while, at least the filing date will be retroactive. Note. The above strategy does not work as well for QMB, because the effective date of QMB is the month after the month of application. As a result, the retroactive effective date of Extra Help will be the month after the failed Extra Help application for those with QMB rather than SLMB/QI-1.

Applying for MSP Directly with Local Medicaid Program. Those who do not have Medicaid already must apply for an MSP through their local social services district. (See more in Section D. Below re those who already have Medicaid through the Affordable Care Act before they became eligible for Medicare. If you are applying for MSP only (not also Medicaid), you can use the simplified MSP application form (theDOH-4328(Rev.

8/2017-- English) (2017 Spanish version not yet available). Either application form can be mailed in -- there is no interview requirement anymore for MSP or Medicaid. See 10 ADM-04. Applicants will need to submit proof of income, a copy of their Medicare card (front &. Back), and proof of residency/address.

See the application form for other instructions. One who is only eligible for QI-1 because of higher income may ONLY apply for an MSP, not for Medicaid too. One may not receive Medicaid and QI-1 at the same time. If someone only eligible for QI-1 wants Medicaid, s/he may enroll in and deposit excess income into a pooled Supplemental Needs Trust, to bring her countable income down to the Medicaid level, which also qualifies him or her for SLIMB or QMB instead of QI-1. Advocates in NYC can sign up for a half-day "Deputization Training" conducted by the Medicare Rights Center, at which you'll be trained and authorized to complete an MSP application and to submit it via the Medicare Rights Center, which submits it to HRA without the client having to apply in person.

Enrolling in an MSP if you already have Medicaid, but just become eligible for Medicare Those who, prior to becoming enrolled in Medicare, had Medicaid through Affordable Care Act are eligible to have their Part B premiums paid by Medicaid (or the cost reimbursed) during the time it takes for them to transition to a Medicare Savings Program. In 2018, DOH clarified that reimbursement of the Part B premium will be made regardless of whether the individual is still in a Medicaid managed care (MMC) plan. GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare ( PDF) provides, "Due to efforts to transition individuals who gain Medicare eligibility and who require LTSS, individuals may not be disenrolled from MMC upon receipt of Medicare. To facilitate the transition and not disadvantage the recipient, the Medicaid program is approving reimbursement of Part B premiums for enrollees in MMC." The procedure for getting the Part B premium paid is different for those whose Medicaid was administered by the NYS of Health Exchange (Marketplace), as opposed to their local social services district. The procedure is also different for those who obtain Medicare because they turn 65, as opposed to obtaining Medicare based on disability.

Either way, Medicaid recipients who transition onto Medicare should be automatically evaluated for MSP eligibility at their next Medicaid recertification. NYS DOH 2000-ADM-7 Individuals can also affirmatively ask to be enrolled in MSP in between recertification periods. IF CLIENT HAD MEDICAID ON THE MARKETPLACE (NYS of Health Exchange) before obtaining Medicare. IF they obtain Medicare because they turn age 65, they will receive a letter from their local district asking them to "renew" Medicaid through their local district. See 2014 LCM-02.

Now, their Medicaid income limit will be lower than the MAGI limits ($842/ mo reduced from $1387/month) and they now will have an asset test. For this reason, some individuals may lose full Medicaid eligibility when they begin receiving Medicare. People over age 65 who obtain Medicare do NOT keep "Marketplace Medicaid" for 12 months (continuous eligibility) See GIS 15 MA/022 - Continuous Coverage for MAGI Individuals. Since MSP has NO ASSET limit. Some individuals may be enrolled in the MSP even if they lose Medicaid, or if they now have a Medicaid spend-down.

If a Medicare/Medicaid recipient reports income that exceeds the Medicaid level, districts must evaluate the person’s eligibility for MSP. 08 OHIP/ADM-4 ​If you became eligible for Medicare based on disability and you are UNDER AGE 65, you are entitled to keep MAGI Medicaid for 12 months from the month it was last authorized, even if you now have income normally above the MAGI limit, and even though you now have Medicare. This is called Continuous Eligibility. EXAMPLE. Sam, age 60, was last authorized for Medicaid on the Marketplace in June 2016.

He became enrolled in Medicare based on disability in August 2016, and started receiving Social Security in the same month (he won a hearing approving Social Security disability benefits retroactively, after first being denied disability). Even though his Social Security is too high, he can keep Medicaid for 12 months beginning June 2016. Sam has to pay for his Part B premium - it is deducted from his Social Security check. He may call the Marketplace and request a refund. This will continue until the end of his 12 months of continues MAGI Medicaid eligibility.

He will be reimbursed regardless of whether he is in a Medicaid managed care plan. See GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare (PDF) When that ends, he will renew Medicaid and apply for MSP with his local district. Individuals who are eligible for Medicaid with a spenddown can opt whether or not to receive MSP. (Medicaid Reference Guide (MRG) p. 19).

Obtaining MSP may increase their spenddown. MIPPA - Outreach by Social Security Administration -- Under MIPPA, the SSA sends a form letter to people who may be eligible for a Medicare Savings Program or Extra Help (Low Income Subsidy - LIS) that they may apply. The letters are. · Beneficiary has Extra Help (LIS), but not MSP · Beneficiary has no Extra Help (LIS) or MSP 6. Enrolling in MSP for People Age 65+ who do Not have Free Medicare Part A - the "Part A Buy-In Program" Seniors WITHOUT MEDICARE PART A or B -- They may be able to enroll in the Part A Buy-In program, in which people eligible for QMB who are age 65+ who do not otherwise have Medicare Part A may enroll in Part A, with Medicaid paying the Part A premium.

See Step-by-Step Guide by the Medicare Rights Center). This guide explains the various steps in "conditionally enrolling" in Part A at the SSA office, which must be done before applying for QMB at the Medicaid office, which will then pay the Part A premium. See also GIS 04 MA/013. In June, 2018, the SSA revised the POMS manual procedures for the Part A Buy-In to to address inconsistencies and confusion in SSA field offices and help smooth the path for QMB enrollment. The procedures are in the POMS Section HI 00801.140 "Premium-Free Part A Enrollments for Qualified Medicare BenefiIaries." It includes important clarifications, such as.

SSA Field Offices should explain the QMB program and conditional enrollment process if an individual lacks premium-free Part A and appears to meet QMB requirements. SSA field offices can add notes to the “Remarks” section of the application and provide a screen shot to the individual so the individual can provide proof of conditional Part A enrollment when applying for QMB through the state Medicaid program. Beneficiaries are allowed to complete the conditional application even if they owe Medicare premiums. In Part A Buy-in states like NYS, SSA should process conditional applications on a rolling basis (without regard to enrollment periods), even if the application coincides with the General Enrollment Period. (The General Enrollment Period is from Jan 1 to March 31st every year, in which anyone eligible may enroll in Medicare Part A or Part B to be effective on July 1st).

7. What happens after the MSP approval - How is Part B premium paid For all three MSP programs, the Medicaid program is now responsible for paying the Part B premiums, even though the MSP enrollee is not necessarily a recipient of Medicaid. The local Medicaid office (DSS/HRA) transmits the MSP approval to the NYS Department of Health – that information gets shared w/ SSA and CMS SSA stops deducting the Part B premiums out of the beneficiary’s Social Security check. SSA also refunds any amounts owed to the recipient. (Note.

This process can take awhile!. !. !. ) CMS “deems” the MSP recipient eligible for Part D Extra Help/ Low Income Subsidy (LIS). ​Can the MSP be retroactive like Medicaid, back to 3 months before the application?.

​The answer is different for the 3 MSP programs. QMB -No Retroactive Eligibility – Benefits begin the month after the month of the MSP application. 18 NYCRR § 360-7.8(b)(5) SLIMB - YES - Retroactive Eligibility up to 3 months before the application, if was eligible This means applicant may be reimbursed for the 3 months of Part B benefits prior to the month of application. QI-1 - YES up to 3 months but only in the same calendar year. No retroactive eligibility to the previous year.

7. QMBs -Special Rules on Cost-Sharing. QMB is the only MSP program which pays not only the Part B premium, but also the Medicare co-insurance. However, there are limitations. First, co-insurance will only be paid if the provide accepts Medicaid.

Not all Medicare provides accept Medicaid. Second, under recent changes in New York law, Medicaid will not always pay the Medicare co-insurance, even to a Medicaid provider. But even if the provider does not accept Medicaid, or if Medicaid does not pay the full co-insurance, the provider is banned from "balance billing" the QMB beneficiary for the co-insurance.

There is usually a lag in time of several weeks, or even months, from January 1st of each year until the new FPLs are release, buy ventolin over the counter uk and then before the new MSP income limits are officially implemented. During this lag period, local Medicaid offices should continue to use the previous year's FPLs AND count the person's Social Security benefit amount from the previous year - do NOT factor in the Social Security COLA (cost of living adjustment).

Once the updated guidelines are released, districts will use the new FPLs and go ahead and factor in any COLA. See 2021 Fact Sheet on MSP in NYS by Medicare Rights Center ENGLISH SPANISH Income is determined by the same methodology as is used for determining in eligibility for buy ventolin over the counter uk SSI The rules for counting income for SSI-related (Aged 65+, Blind, or Disabled) Medicaid recipients, borrowed from the SSI program, apply to the MSP program, except for the new rules about counting household size for married couples. N.Y. Soc.

Serv. L. 367-a(3)(c)(2), NYS DOH 2000-ADM-7, 89-ADM-7 p.7. Gross income is counted, although there are certain types of income that are disregarded.

The most common income disregards, also known as deductions, include. (a) The first $20 of your &. Your spouse's monthly income, earned or unearned ($20 per couple max). (b) SSI EARNED INCOME DISREGARDS.

* The first $65 of monthly wages of you and your spouse, * One-half of the remaining monthly wages (after the $65 is deducted). * Other work incentives including PASS plans, impairment related work expenses (IRWEs), blind work expenses, etc. For information on these deductions, see The Medicaid Buy-In for Working People with Disabilities (MBI-WPD) and other guides in this article -- though written for the MBI-WPD, the work incentives apply to all Medicaid programs, including MSP, for people age 65+, disabled or blind. (c) monthly cost of any health insurance premiums but NOT the Part B premium, since Medicaid will now pay this premium (may deduct Medigap supplemental policies, vision, dental, or long term care insurance premiums, and the Part D premium but only to the extent the premium exceeds the Extra Help benchmark amount) (d) Food stamps not counted.

You can get a more comprehensive listing of the SSI-related income disregards on the Medicaid income disregards chart. As for all benefit programs based on financial need, it is usually advantageous to be considered a larger household, because the income limit is higher. The above chart shows that Households of TWO have a higher income limit than households of ONE. The MSP programs use the same rules as Medicaid does for the Disabled, Aged and Blind (DAB) which are borrowed from the SSI program for Medicaid recipients in the “SSI-related category.” Under these rules, a household can be only ONE or TWO.

18 NYCRR 360-4.2. See DAB Household Size Chart. Married persons can sometimes be ONE or TWO depending on arcane rules, which can force a Medicare beneficiary to be limited to the income limit for ONE person even though his spouse who is under 65 and not disabled has no income, and is supported by the client applying for an MSP. EXAMPLE.

Bob's Social Security is $1300/month. He is age 67 and has Medicare. His wife, Nancy, is age 62 and is not disabled and does not work. Under the old rule, Bob was not eligible for an MSP because his income was above the Income limit for One, even though it was well under the Couple limit.

In 2010, NYS DOH modified its rules so that all married individuals will be considered a household size of TWO. DOH GIS 10 MA 10 Medicare Savings Program Household Size, June 4, 2010. This rule for household size is an exception to the rule applying SSI budgeting rules to the MSP program. Under these rules, Bob is now eligible for an MSP.

When is One Better than Two?. Of course, there may be couples where the non-applying spouse's income is too high, and disqualifies the applying spouse from an MSP. In such cases, "spousal refusal" may be used SSL 366.3(a). (Link is to NYC HRA form, can be adapted for other counties).

In NYC, if you have a Medicaid case with HRA, instead of submitting an MSP application, you only need to complete and submit MAP-751W (check off "Medicare Savings Program Evaluation") and fax to (917) 639-0837. (The MAP-751W is also posted in languages other than English in this link. (Updated 4/14/2021.)) 3. The Three Medicare Savings Programs - what are they and how are they different?.

1. Qualified Medicare Beneficiary (QMB). The QMB program provides the most comprehensive benefits. Available to those with incomes at or below 100% of the Federal Poverty Level (FPL), the QMB program covers virtually all Medicare cost-sharing obligations.

Part B premiums, Part A premiums, if there are any, and any and all deductibles and co-insurance. QMB coverage is not retroactive. The program’s benefits will begin the month after the month in which your client is found eligible. ** See special rules about cost-sharing for QMBs below - updated with new CMS directive issued January 2012 ** See NYC HRA QMB Recertification form ** Even if you do not have Part A automatically, because you did not have enough wages, you may be able to enroll in the Part A Buy-In Program, in which people eligible for QMB who do not otherwise have Medicare Part A may enroll, with Medicaid paying the Part A premium (Materials by the Medicare Rights Center).

2. Specifiedl Low-Income Medicare Beneficiary (SLMB). For those with incomes between 100% and 120% FPL, the SLMB program will cover Part B premiums only. SLMB is retroactive, however, providing coverage for three months prior to the month of application, as long as your client was eligible during those months.

3. Qualified Individual (QI-1). For those with incomes between 120% and 135% FPL, and not receiving Medicaid, the QI-1 program will cover Medicare Part B premiums only. QI-1 is also retroactive, providing coverage for three months prior to the month of application, as long as your client was eligible during those months.

However, QI-1 retroactive coverage can only be provided within the current calendar year. (GIS 07 MA 027) So if you apply in January, you get no retroactive coverage. Q-I-1 recipients would be eligible for Medicaid with a spend-down, but if they want the Part B premium paid, they must choose between enrolling in QI-1 or Medicaid. They cannot be in both.

It is their choice. DOH MRG p. 19. In contrast, one may receive Medicaid and either QMB or SLIMB.

4. Four Special Benefits of MSPs (in addition to NO ASSET TEST). Benefit 1. Back Door to Medicare Part D "Extra Help" or Low Income Subsidy -- All MSP recipients are automatically enrolled in Extra Help, the subsidy that makes Part D affordable.

They have no Part D deductible or doughnut hole, the premium is subsidized, and they pay very low copayments. Once they are enrolled in Extra Help by virtue of enrollment in an MSP, they retain Extra Help for the entire calendar year, even if they lose MSP eligibility during that year. The "Full" Extra Help subsidy has the same income limit as QI-1 - 135% FPL. However, many people may be eligible for QI-1 but not Extra Help because QI-1 and the other MSPs have no asset limit.

People applying to the Social Security Administration for Extra Help might be rejected for this reason. Recent (2009-10) changes to federal law called "MIPPA" requires the Social Security Administration (SSA) to share eligibility data with NYSDOH on all persons who apply for Extra Help/ the Low Income Subsidy. Data sent to NYSDOH from SSA will enable NYSDOH to open MSP cases on many clients. The effective date of the MSP application must be the same date as the Extra Help application.

Signatures will not be required from clients. In cases where the SSA data is incomplete, NYSDOH will forward what is collected to the local district for completion of an MSP application. The State implementing procedures are in DOH 2010 ADM-03. Also see CMS "Dear State Medicaid Director" letter dated Feb.

18, 2010 Benefit 2. MSPs Automatically Waive Late Enrollment Penalties for Part B Generally one must enroll in Part B within the strict enrollment periods after turning age 65 or after 24 months of Social Security Disability. An exception is if you or your spouse are still working and insured under an employer sponsored group health plan, or if you have End Stage Renal Disease, and other factors, see this from Medicare Rights Center. If you fail to enroll within those short periods, you might have to pay higher Part B premiums for life as a Late Enrollment Penalty (LEP).

Also, you may only enroll in Part B during the Annual Enrollment Period from January 1 - March 31st each year, with Part B not effective until the following July. Enrollment in an MSP automatically eliminates such penalties... For life.. Even if one later ceases to be eligible for the MSP.

AND enrolling in an MSP will automatically result in becoming enrolled in Part B if you didn't already have it and only had Part A. See Medicare Rights Center flyer. Benefit 3. No Medicaid Lien on Estate to Recover MSP Benefits Paid Generally speaking, states may place liens on the Estates of deceased Medicaid recipients to recover the cost of Medicaid services that were provided after the recipient reached the age of 55.

Since 2002, states have not been allowed to recover the cost of Medicare premiums paid under MSPs. In 2010, Congress expanded protection for MSP benefits. Beginning on January 1, 2010, states may not place liens on the Estates of Medicaid recipients who died after January 1, 2010 to recover costs for co-insurance paid under the QMB MSP program for services rendered after January 1, 2010. The federal government made this change in order to eliminate barriers to enrollment in MSPs.

See NYS DOH GIS 10-MA-008 - Medicare Savings Program Changes in Estate Recovery The GIS clarifies that a client who receives both QMB and full Medicaid is exempt from estate recovery for these Medicare cost-sharing expenses. Benefit 4. SNAP (Food Stamp) benefits not reduced despite increased income from MSP - at least temporarily Many people receive both SNAP (Food Stamp) benefits and MSP. Income for purposes of SNAP/Food Stamps is reduced by a deduction for medical expenses, which includes payment of the Part B premium.

Since approval for an MSP means that the client no longer pays for the Part B premium, his/her SNAP/Food Stamps income goes up, so their SNAP/Food Stamps go down. Here are some protections. Do these individuals have to report to their SNAP worker that their out of pocket medical costs have decreased?. And will the household see a reduction in their SNAP benefits, since the decrease in medical expenses will increase their countable income?.

The good news is that MSP households do NOT have to report the decrease in their medical expenses to the SNAP/Food Stamp office until their next SNAP/Food Stamp recertification. Even if they do report the change, or the local district finds out because the same worker is handling both the MSP and SNAP case, there should be no reduction in the household’s benefit until the next recertification. New York’s SNAP policy per administrative directive 02 ADM-07 is to “freeze” the deduction for medical expenses between certification periods. Increases in medical expenses can be budgeted at the household’s request, but NYS never decreases a household’s medical expense deduction until the next recertification.

Most elderly and disabled households have 24-month SNAP certification periods. Eventually, though, the decrease in medical expenses will need to be reported when the household recertifies for SNAP, and the household should expect to see a decrease in their monthly SNAP benefit. It is really important to stress that the loss in SNAP benefits is NOT dollar for dollar. A $100 decrease in out of pocket medical expenses would translate roughly into a $30 drop in SNAP benefits.

See more info on SNAP/Food Stamp benefits by the Empire Justice Center, and on the State OTDA website. Some clients will be automatically enrolled in an MSP by the New York State Department of Health (NYSDOH) shortly after attaining eligibility for Medicare. Others need to apply. The 2010 "MIPPA" law introduced some improvements to increase MSP enrollment.

See 3rd bullet below. Also, some people who had Medicaid through the Affordable Care Act before they became eligible for Medicare have special procedures to have their Part B premium paid before they enroll in an MSP. See below. WHO IS AUTOMATICALLY ENROLLED IN AN MSP.

Clients receiving even $1.00 of Supplemental Security Income should be automatically enrolled into a Medicare Savings Program (most often QMB) under New York State’s Medicare Savings Program Buy-in Agreement with the federal government once they become eligible for Medicare. They should receive Medicare Parts A and B. Clients who are already eligible for Medicare when they apply for Medicaid should be automatically assessed for MSP eligibility when they apply for Medicaid. (NYS DOH 2000-ADM-7 and GIS 05 MA 033).

Clients who apply to the Social Security Administration for Extra Help, but are rejected, should be contacted &. Enrolled into an MSP by the Medicaid program directly under new MIPPA procedures that require data sharing. Strategy TIP. Since the Extra Help filing date will be assigned to the MSP application, it may help the client to apply online for Extra Help with the SSA, even knowing that this application will be rejected because of excess assets or other reason.

SSA processes these requests quickly, and it will be routed to the State for MSP processing. Since MSP applications take a while, at least the filing date will be retroactive. Note. The above strategy does not work as well for QMB, because the effective date of QMB is the month after the month of application.

As a result, the retroactive effective date of Extra Help will be the month after the failed Extra Help application for those with QMB rather than SLMB/QI-1. Applying for MSP Directly with Local Medicaid Program. Those who do not have Medicaid already must apply for an MSP through their local social services district. (See more in Section D.

Below re those who already have Medicaid through the Affordable Care Act before they became eligible for Medicare. If you are applying for MSP only (not also Medicaid), you can use the simplified MSP application form (theDOH-4328(Rev. 8/2017-- English) (2017 Spanish version not yet available). Either application form can be mailed in -- there is no interview requirement anymore for MSP or Medicaid.

See 10 ADM-04. Applicants will need to submit proof of income, a copy of their Medicare card (front &. Back), and proof of residency/address. See the application form for other instructions.

One who is only eligible for QI-1 because of higher income may ONLY apply for an MSP, not for Medicaid too. One may not receive Medicaid and QI-1 at the same time. If someone only eligible for QI-1 wants Medicaid, s/he may enroll in and deposit excess income into a pooled Supplemental Needs Trust, to bring her countable income down to the Medicaid level, which also qualifies him or her for SLIMB or QMB instead of QI-1. Advocates in NYC can sign up for a half-day "Deputization Training" conducted by the Medicare Rights Center, at which you'll be trained and authorized to complete an MSP application and to submit it via the Medicare Rights Center, which submits it to HRA without the client having to apply in person.

Enrolling in an MSP if you already have Medicaid, but just become eligible for Medicare Those who, prior to becoming enrolled in Medicare, had Medicaid through Affordable Care Act are eligible to have their Part B premiums paid by Medicaid (or the cost reimbursed) during the time it takes for them to transition to a Medicare Savings Program. In 2018, DOH clarified that reimbursement of the Part B premium will be made regardless of whether the individual is still in a Medicaid managed care (MMC) plan. GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare ( PDF) provides, "Due to efforts to transition individuals who gain Medicare eligibility and who require LTSS, individuals may not be disenrolled from MMC upon receipt of Medicare. To facilitate the transition and not disadvantage the recipient, the Medicaid program is approving reimbursement of Part B premiums for enrollees in MMC." The procedure for getting the Part B premium paid is different for those whose Medicaid was administered by the NYS of Health Exchange (Marketplace), as opposed to their local social services district.

The procedure is also different for those who obtain Medicare because they turn 65, as opposed to obtaining Medicare based on disability. Either way, Medicaid recipients who transition onto Medicare should be automatically evaluated for MSP eligibility at their next Medicaid recertification. NYS DOH 2000-ADM-7 Individuals can also affirmatively ask to be enrolled in MSP in between recertification periods. IF CLIENT HAD MEDICAID ON THE MARKETPLACE (NYS of Health Exchange) before obtaining Medicare.

IF they obtain Medicare because they turn age 65, they will receive a letter from their local district asking them to "renew" Medicaid through their local district. See 2014 LCM-02. Now, their Medicaid income limit will be lower than the MAGI limits ($842/ mo reduced from $1387/month) and they now will have an asset test. For this reason, some individuals may lose full Medicaid eligibility when they begin receiving Medicare.

People over age 65 who obtain Medicare do NOT keep "Marketplace Medicaid" for 12 months (continuous eligibility) See GIS 15 MA/022 - Continuous Coverage for MAGI Individuals. Since MSP has NO ASSET limit. Some individuals may be enrolled in the MSP even if they lose Medicaid, or if they now have a Medicaid spend-down. If a Medicare/Medicaid recipient reports income that exceeds the Medicaid level, districts must evaluate the person’s eligibility for MSP.

08 OHIP/ADM-4 ​If you became eligible for Medicare based on disability and you are UNDER AGE 65, you are entitled to keep MAGI Medicaid for 12 months from the month it was last authorized, even if you now have income normally above the MAGI limit, and even though you now have Medicare. This is called Continuous Eligibility. EXAMPLE. Sam, age 60, was last authorized for Medicaid on the Marketplace in June 2016.

He became enrolled in Medicare based on disability in August 2016, and started receiving Social Security in the same month (he won a hearing approving Social Security disability benefits retroactively, after first being denied disability). Even though his Social Security is too high, he can keep Medicaid for 12 months beginning June 2016. Sam has to pay for his Part B premium - it is deducted from his Social Security check. He may call the Marketplace and request a refund.

This will continue until the end of his 12 months of continues MAGI Medicaid eligibility. He will be reimbursed regardless of whether he is in a Medicaid managed care plan. See GIS 18 MA/001 Medicaid Managed Care Transition for Enrollees Gaining Medicare (PDF) When that ends, he will renew Medicaid and apply for MSP with his local district. Individuals who are eligible for Medicaid with a spenddown can opt whether or not to receive MSP.

(Medicaid Reference Guide (MRG) p. 19). Obtaining MSP may increase their spenddown. MIPPA - Outreach by Social Security Administration -- Under MIPPA, the SSA sends a form letter to people who may be eligible for a Medicare Savings Program or Extra Help (Low Income Subsidy - LIS) that they may apply.

The letters are. · Beneficiary has Extra Help (LIS), but not MSP · Beneficiary has no Extra Help (LIS) or MSP 6. Enrolling in MSP for People Age 65+ who do Not have Free Medicare Part A - the "Part A Buy-In Program" Seniors WITHOUT MEDICARE PART A or B -- They may be able to enroll in the Part A Buy-In program, in which people eligible for QMB who are age 65+ who do not otherwise have Medicare Part A may enroll in Part A, with Medicaid paying the Part A premium. See Step-by-Step Guide by the Medicare Rights Center).

This guide explains the various steps in "conditionally enrolling" in Part A at the SSA office, which must be done before applying for QMB at the Medicaid office, which will then pay the Part A premium. See also GIS 04 MA/013. In June, 2018, the SSA revised the POMS manual procedures for the Part A Buy-In to to address inconsistencies and confusion in SSA field offices and help smooth the path for QMB enrollment. The procedures are in the POMS Section HI 00801.140 "Premium-Free Part A Enrollments for Qualified Medicare BenefiIaries." It includes important clarifications, such as.

SSA Field Offices should explain the QMB program and conditional enrollment process if an individual lacks premium-free Part A and appears to meet QMB requirements. SSA field offices can add notes to the “Remarks” section of the application and provide a screen shot to the individual so the individual can provide proof of conditional Part A enrollment when applying for QMB through the state Medicaid program. Beneficiaries are allowed to complete the conditional application even if they owe Medicare premiums. In Part A Buy-in states like NYS, SSA should process conditional applications on a rolling basis (without regard to enrollment periods), even if the application coincides with the General Enrollment Period.

(The General Enrollment Period is from Jan 1 to March 31st every year, in which anyone eligible may enroll in Medicare Part A or Part B to be effective on July 1st). 7. What happens after the MSP approval - How is Part B premium paid For all three MSP programs, the Medicaid program is now responsible for paying the Part B premiums, even though the MSP enrollee is not necessarily a recipient of Medicaid. The local Medicaid office (DSS/HRA) transmits the MSP approval to the NYS Department of Health – that information gets shared w/ SSA and CMS SSA stops deducting the Part B premiums out of the beneficiary’s Social Security check.

SSA also refunds any amounts owed to the recipient. (Note. This process can take awhile!. !.

!. ) CMS “deems” the MSP recipient eligible for Part D Extra Help/ Low Income Subsidy (LIS). ​Can the MSP be retroactive like Medicaid, back to 3 months before the application?. ​The answer is different for the 3 MSP programs.

QMB -No Retroactive Eligibility – Benefits begin the month after the month of the MSP application. 18 NYCRR § 360-7.8(b)(5) SLIMB - YES - Retroactive Eligibility up to 3 months before the application, if was eligible This means applicant may be reimbursed for the 3 months of Part B benefits prior to the month of application. QI-1 - YES up to 3 months but only in the same calendar year. No retroactive eligibility to the previous year.

7. QMBs -Special Rules on Cost-Sharing. QMB is the only MSP program which pays not only the Part B premium, but also the Medicare co-insurance.

How much does ventolin cost without insurance

IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1–13 Based on these studies, how much does ventolin cost without insurance it has become clear that services and institutions still differ in the composition of the multidisciplinary teams that provide care for patients who have a DSD.11 14 Several projects have now worked to resolve this variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 ‘A systematic elucidation of differences of sex development’ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15–17 Another such initiative involved an update how much does ventolin cost without insurance of the 2006 DSD consensus document by an international group of professionals and patient representatives.18 These initiatives have highlighted how cultural and financial aspects and the availability of resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them.

Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the Dutch-speaking Northern part of Belgium) have collaborated to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can how much does ventolin cost without insurance be a reasonable approach for countries with similarly structured healthcare systems and similar resources. Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues. International networks such as the European how much does ventolin cost without insurance Reference Network for rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders.

For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 how much does ventolin cost without insurance 21 Furthermore, informing patients and/or their parents about atypical sex development and why this may warrant referral to a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section of the Dutch-Flemish guideline was written for these healthcare providers. Moreover, this enables DSD specialists to refer to the guideline when advising a referral.

Transition from the prenatal to the postnatal team and from the paediatric to the adult team requires optimal communication how much does ventolin cost without insurance between the specialists involved. Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue is challenging and would benefit from how much does ventolin cost without insurance international collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre group was formed with all members responsible for updating the literature for a specific part of the guideline.

Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory Document method described by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the rapid changes in testing methods, for how much does ventolin cost without insurance example, gene panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper.

Abstracts had to be written in English and were identified using a broad range of Medical Subject Headings how much does ventolin cost without insurance terms (eg, DSD, genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care). Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as were articles how much does ventolin cost without insurance that were not open access or retrievable through institutional access.

Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft was discussed by the writing how much does ventolin cost without insurance committee and, after having obtained agreement on remaining points of discussion, revised into a final draft. This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline.

After receiving and incorporating their input, the final version was presented to the paediatric how much does ventolin cost without insurance and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed at the request of the parents.Another way DSD can be how much does ventolin cost without insurance diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the genotypic sex and the phenotypic sex seen by ultrasound.

In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately. More often, the discrepancy will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which is now available to how much does ventolin cost without insurance high-risk pregnant women in the Netherlands and to all pregnant women in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus.

However, depending on legal restrictions and/or ethical considerations, the X and Y chromosomes are not always included in NIPT analysis and how much does ventolin cost without insurance reports. If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11–13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or atypical aspect of the genitalia will only be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf a DSD is suspected, first-line sonographers and obstetricians should refer how much does ventolin cost without insurance the couple to their colleague prenatal specialists working with or in a DSD team.

After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on the ultrasound findings and the limitations of this how much does ventolin cost without insurance technique. The procedure(s) that can be followed, including the risks associated with an amniocentesis.

And the type of information genetic testing can how much does ventolin cost without insurance and cannot provide. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the child’s future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved. The clinical geneticist should be experienced in prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which how much does ventolin cost without insurance test results need to be available to allow parents to make a well-informed decision about whether or not to continue the pregnancy.

Termination of pregnancy can be considered, for instance, in a syndromic form of DSD with multiple malformations, but when the DSD occurs as an apparently isolated condition, expecting parents may also consider how much does ventolin cost without insurance termination of pregnancy, which, although considered controversial by some, is legal in Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not knowing exactly what the how much does ventolin cost without insurance child’s genitalia will look like and uncertainty about the diagnosis, treatment and prognosis cannot be avoided completely.

Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images. In our experience, how much does ventolin cost without insurance parents appreciate having already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of pregnant couples decline prenatal testing (personal experience IALG, MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist.

The terminology used in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, ‘your baby’) how much does ventolin cost without insurance as long as sex assignment is pending.An algorithm for diagnostic evaluation of a suspected DSD in the prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array. It was recently estimated that >30% of individuals who have a DSD how much does ventolin cost without insurance have additional structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, the geneticist can consider specific gene defects that may underlie a known genetic syndrome or carry out NGS.

NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parents’ genetics.29–31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there is no tight time limit, and we propose completing the analysis how much does ventolin cost without insurance well before the expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition.

Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.

The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their child’s sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers.

A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline. Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively. Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process.

Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48 hours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

Conventional karyotyping can be useful. NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype.

Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35–38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned. Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences.

If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilms’ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing. Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing.

Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthors’ institutions can be found on their respective websites. Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another.

This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions.

What do laboratories report?. How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity.

It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype. This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD.

In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring.

This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41–44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise. For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium.

We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15–17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48–50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time. Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD.

These should be published in widely available general medical journals and online, along with a national list of DSD centres. Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions. One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved.

A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.

This will enable highly individualised holistic care tailored to the patient’s needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15–17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication.

Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing. Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseases—Project ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic. In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5 year survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation of endometrial tumours into four groups with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors.

Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3–5% of cases.8–10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers. Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality.

Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation.

We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2. Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk.

Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used. €œendomet*”,“uter*”, “womb”, “cancer(s)”, “neoplasm(s)”, “endometrium tumour”, “carcinoma”, “adenosarcoma”, “clear cell carcinoma”, “carcinosarcoma”, “SNP”, “single nucleotide polymorphism”, “GWAS”, and “genome-wide association study/ies”.

No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion.

Chronbach’s α score was calculated between reviewers and indicated high consistency at 0.92. Case–control, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected.

For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected. Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95% CI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis.

For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5×10-8, indicating genome-wide significance, was accepted as statistically significant. However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1×10-5, allowing for marginally significant SNPs to be included.

As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs. The PRS was assumed to have a Normal distribution, with mean 2∑βipI and SE, σ, equal to √2∑βi2pI(1−pi), according to the binomial distribution, where the summation is over all SNPs in the risk score.

Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01σ), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis.

Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported. Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21–25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21–25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies.

Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28–30 Moreover, a recent article authored by O’Mara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations. Those having a multi-ethnic cohort also consisted primarily of broad European populations. Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene.

Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene. The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95% CI 1.32 to 2.04.

P=9.6×10-6) compared with the endometrioid arm (OR 1.25, 95% CI 1.14 to 1.38. P=4.7×10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. O’Mara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86×10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis.

It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer.

These can be activated by high levels of KLF5 (transcriptional activator). Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95% CI 1.11 to 1.21.

P=4.83×10-11), the A allele of rs9600103 (OR 1.23, 95% CI 1.16 to 1.30. P=3.76×10-12) and C allele of rs7981863 (OR 1.16, 95% CI 1.12 to 1.20. P=2.70×10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated.

The recent GWAS by O’Mara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5×10–8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele.

Two more original studies were identified through our full-text evaluation. However, these were not included here as they did not meet our inclusion criteria—one due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses.

However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13 000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry. There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42–44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer.

We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant. The largest GWAS conducted in this field was the discovery- and meta-GWAS by O’Mara et al, which utilised 12 096 cases and 108 979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer.

For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200 000 individuals with more than half being cases, and resulted in identification of ~170 SNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150 000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS. The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s.

However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95% CI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality.

Thus, these should be interpreted with caution. Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by O’Mara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants.

However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs. It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data.

This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data.

Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene. In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit.

In order to elucidate biologically relevant candidate target genes in endometrial cancer, O’Mara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS. Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1.

Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14. In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A. This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes.

The study looked at protein–protein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.

Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women.

This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans. This poses a problem for developing risk prediction models that are equally valuable and predictive across populations. Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours.

Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer. It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes.

It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhman’s classification system, type I versus type II, or no histological classification system at all. Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk.

Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations.

Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk. The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..

IntroductionIn recent years, many studies have been published on new diagnostic possibilities and management approaches in cohorts of patients suspected to have a disorder/difference of sex development (DSD).1–13 Based on these studies, it has become clear that services and institutions still differ in the buy ventolin over the counter uk composition of the multidisciplinary teams that provide care for patients who have a DSD.11 14 Several projects have now worked to resolve this variability in care. The European Cooperation in Science and Technology (EU COST) action BM1303 ‘A systematic elucidation of differences of sex development’ has been a platform to achieve European agreement on harmonisation of clinical management and laboratory practices.15–17 Another such initiative involved an update of the 2006 DSD consensus document by an international group of professionals and patient representatives.18 These initiatives have highlighted how cultural and financial aspects and the availability of buy ventolin over the counter uk resources differ significantly between countries and societies, a situation that hampers supranational agreement on common diagnostic protocols. As only a few national guidelines have been published in international journals, comparison of these guidelines is difficult even though such a comparison is necessary to capture the differences and initiate actions to overcome them.

Nonetheless, four DSD (expert) centres located in the Netherlands and Flanders (the Dutch-speaking Northern part of buy ventolin over the counter uk Belgium) have collaborated to produce a detailed guideline on diagnostics in DSD.19 This shows that a supranational guideline can be a reasonable approach for countries with similarly structured healthcare systems and similar resources. Within the guideline there is agreement that optimisation of expertise and care can be achieved through centralisation, for example, by limiting analysis of next-generation sequencing (NGS)-based diagnostic panels to only a few centres and by centralising pathological review of gonadal tissues. International networks such as the European Reference Network for rare endocrine conditions (EndoERN), in which DSD is embedded, may facilitate the expansion of this kind buy ventolin over the counter uk of collaboration across Europe.This paper highlights key discussion points in the Dutch-Flemish guideline that have been insufficiently addressed in the literature thus far because they reflect evolving technologies or less visible stakeholders.

For example, prenatal observation of an atypical aspect of the genitalia indicating a possible DSD is becoming increasingly common, and we discuss appropriate counselling and a diagnostic approach for these cases, including the option of using NGS-based genetic testing. So far, little attention has been paid to this process.20 21 Furthermore, informing patients and/or their parents about atypical sex development and why this may warrant referral to a specialised team may be challenging, especially for professionals with limited experience in DSD.22 23 Therefore, a section buy ventolin over the counter uk of the Dutch-Flemish guideline was written for these healthcare providers. Moreover, this enables DSD specialists to refer to the guideline when advising a referral.

Transition from the prenatal to the postnatal team and from the paediatric buy ventolin over the counter uk to the adult team requires optimal communication between the specialists involved. Application of NGS-based techniques may lead to a higher diagnostic yield, providing a molecular genetic diagnosis in previously unsolved cases.16 We address the timing of this testing and the problems associated with this technique such as the interpretation of variants of unknown clinical significance (VUS). Similarly, histopathological interpretation and classification of removed gonadal tissue is challenging and would benefit from international collaboration and centralisation of expertise.MethodsFor the guideline revision, an interdisciplinary multicentre group was formed with all members responsible for updating the literature for a specific part of the buy ventolin over the counter uk guideline.

Literature search in PubMed was not systematic, but rather intended to be broad in order to cover all areas and follow expert opinions. This approach is more in line with the Clinical Practice Advisory Document method described buy ventolin over the counter uk by Burke et al24 for guidelines involving genetic practice because it is often troublesome to substantiate such guidelines with sufficient evidence due to the rapid changes in testing methods, for example, gene panels. All input provided by the group was synthesised by the chairperson (YvB), who also reviewed abstracts of papers on DSD published between 2010 and September 2017 for the guideline and up to October 2019 for this paper.

Abstracts had to be written in English and were identified using a broad range of buy ventolin over the counter uk Medical Subject Headings terms (eg, DSD, genetic, review, diagnosis, diagnostics, 46,XX DSD, 46,XY DSD, guideline, multidisciplinary care). Next, potentially relevant papers on diagnostic procedures in DSD were selected. Case reports were excluded, as were articles that were not open access buy ventolin over the counter uk or retrievable through institutional access.

Based on this, a draft guideline was produced that was in line with the international principles of good diagnostic care in DSD. This draft was discussed by the writing committee and, after having obtained buy ventolin over the counter uk agreement on remaining points of discussion, revised into a final draft. This version was sent to a broad group of professionals from academic centres and DSD teams whose members had volunteered to review the draft guideline.

After receiving and incorporating their buy ventolin over the counter uk input, the final version was presented to the paediatric and genetic associations for approval. After approval by the members of the paediatric (NVK), clinical genetic (VKGN) and genetic laboratory (VKGL) associations, the guideline was published on their respective websites.19 Although Turner syndrome and Klinefelter syndrome are considered to be part of the DSD spectrum, they are not extensively discussed in this diagnostic guideline as guidelines dedicated to these syndromes already exist.25 26 However, some individuals with Turner syndrome or Klinefelter syndrome may present with ambiguous or atypical genitalia and may therefore initially follow the DSD diagnostic process.Guideline highlightsPrenatal settingPresentationThe most frequent prenatal presentation of a DSD condition is atypical genitalia found on prenatal ultrasound as an isolated finding or in combination with other structural anomalies. This usually occurs after the 20-week routine medical ultrasound for screening of congenital anomalies, but may also occur earlier, for example, when a commercial ultrasound is performed at the request of the parents.Another way DSD can buy ventolin over the counter uk be diagnosed before birth is when invasive prenatal genetic testing carried out for a different reason, for example, due to suspicion of other structural anomalies, reveals a discrepancy between the genotypic sex and the phenotypic sex seen by ultrasound.

In certified laboratories, the possibility of a sample switch is extremely low but should be ruled out immediately. More often, the discrepancy will be due to sex-chromosome mosaicism or a true form of DSD.A situation now occurring with increasing frequency is a discrepancy between the genotypic sex revealed by non-invasive prenatal testing (NIPT), which buy ventolin over the counter uk is now available to high-risk pregnant women in the Netherlands and to all pregnant women in Belgium, and later ultrasound findings. NIPT screens for CNVs in the fetus.

However, depending on legal restrictions and/or ethical considerations, the X and Y chromosomes are buy ventolin over the counter uk not always included in NIPT analysis and reports. If the X and Y chromosomes are included, it is important to realise that the presence of a Y-chromosome does not necessarily imply male fetal development. At the time that NIPT is performed (usually 11–13 weeks), genital development cannot be reliably appreciated by ultrasound, so any discrepancy or buy ventolin over the counter uk atypical aspect of the genitalia will only be noticed later in pregnancy and should prompt further evaluation.Counselling and diagnosticsIf a DSD is suspected, first-line sonographers and obstetricians should refer the couple to their colleague prenatal specialists working with or in a DSD team.

After confirming an atypical genital on ultrasound, the specialist team should offer the couple a referral for genetic counselling to discuss the possibility of performing invasive prenatal testing (usually an amniocentesis) to identify an underlying cause that fits the ultrasound findings.22 23 To enable the parents to make a well-informed decision, prenatal counselling should, in our opinion, include. Information on buy ventolin over the counter uk the ultrasound findings and the limitations of this technique. The procedure(s) that can be followed, including the risks associated with an amniocentesis.

And the type of information genetic buy ventolin over the counter uk testing can and cannot provide. Knowing which information has been provided and what words have been used by the prenatal specialist is very helpful for those involved in postnatal care.It is important that parents understand that the biological sex of a baby is determined by a complex interplay of chromosomes, genes and hormones, and thus that assessment of the presence or absence of a Y-chromosome alone is insufficient to assign the sex of their unborn child or, as in any unborn child, say anything about the child’s future gender identity.Expecting parents can be counselled by the clinical geneticist and the psychologist from the DSD team, although other DSD specialists can also be involved. The clinical geneticist should be experienced in prenatal counselling and well informed about the diagnostic possibilities given the limited time span in which test results need to be available to allow parents to make a well-informed buy ventolin over the counter uk decision about whether or not to continue the pregnancy.

Termination of pregnancy can be considered, for instance, in a syndromic form buy ventolin over the counter uk of DSD with multiple malformations, but when the DSD occurs as an apparently isolated condition, expecting parents may also consider termination of pregnancy, which, although considered controversial by some, is legal in Belgium and the Netherlands. The psychologist of the DSD team can support parents during and after pregnancy and help them cope with feelings of uncertainty and eventual considerations of a termination of pregnancy, as well as with practical issues, for example, how to inform others. The stress of not knowing exactly what the child’s genitalia will look like and uncertainty about the diagnosis, treatment and prognosis cannot be avoided completely buy ventolin over the counter uk.

Parents are informed that if the postnatal phenotype is different from what was prenatally expected, the advice given about diagnostic testing can be adjusted accordingly, for example, if a hypospadias is milder than was expected based on prenatal ultrasound images. In our experience, parents appreciate having already spoken to some members of the DSD team during pregnancy and having a contact person before birth.After expert prenatal counselling, a significant number of pregnant couples decline buy ventolin over the counter uk prenatal testing (personal experience IALG, MK, ABD, YvB, MC and HC-vdG). At birth, umbilical cord blood is a good source for (molecular) karyotyping and storage of DNA and can be obtained by the obstetrician, midwife or neonatologist.

The terminology used in communication with parents should be carefully chosen,22 23 and midwives and staff of neonatal and delivery units should be clearly instructed to use gender-neutral and non-stigmatising vocabulary (eg, ‘your baby’) as long as sex assignment is pending.An algorithm for diagnostic evaluation of buy ventolin over the counter uk a suspected DSD in the prenatal situation is proposed in figure 1. When couples opt for invasive prenatal diagnosis, the genetic analysis usually involves an (SNP)-array. It was recently estimated that >30% of individuals who have a DSD have additional buy ventolin over the counter uk structural anomalies, with cardiac and neurological anomalies and fetal growth restriction being particularly common.27 28 If additional anomalies are seen, the geneticist can consider specific gene defects that may underlie a known genetic syndrome or carry out NGS.

NGS-based techniques have also now made their appearance in prenatal diagnosis of congenital anomalies.29 30 Panels using these techniques can be specific for genes involved in DSD, or be larger panels covering multiple congenital anomalies, and are usually employed with trio-analysis to compare variants identified in the child with the parents’ genetics.29–31 Finding a genetic cause before delivery can help reduce parental stress in the neonatal period and speed up decisions regarding gender assignment. In such cases there is no tight time limit, buy ventolin over the counter uk and we propose completing the analysis well before the expected delivery.Disorders/differences of sex development (DSD) in the prenatal setting.

NGS, next-generation sequencing.First contact by a professional less experienced in DSDWhereas most current guidelines start from the point when an individual has been referred to the DSD team,1 15 the Dutch-Flemish guideline dedicates a chapter to healthcare professionals less experienced in DSD as they are often the first to suspect or identify such a condition.

Apart from the paper of Indyk,7 little guidance is available for these professionals about how to act in such a situation. The chapter in the Dutch-Flemish guideline summarises the various clinical presentations that a DSD can have and provides information on how to communicate with parents and/or patients about the findings of the physical examination, the first-line investigations and the need for prompt referral to a specialised centre for further evaluation. Clinical examples are offered to illustrate some of these recurring situations.

The medical issues in DSD can be very challenging, and the social and psychological impact is high. For neonates with ambiguous genitalia, sex assignment is an urgent and crucial issue, and it is mandatory that parents are informed that it is possible to postpone registration of their child’s sex. In cases where sex assignment has already taken place, the message that the development of the gonads or genitalia is still atypical is complicated and distressing for patients and parents or carers.

A list of contact details for DSD centres and patient organisations in the Netherlands and Flanders is attached to the Dutch-Flemish guideline. Publishing such a list, either in guidelines or online, can help healthcare professionals find the nearest centres for consultations and provide patients and patient organisations with an overview of the centres where expertise is available.Timing and place of genetic testing using NGS-based gene panelsThe diagnostic workup that is proposed for 46,XX and 46,XY DSD is shown in figures 2 and 3, respectively. Even with the rapidly expanding molecular possibilities, a (family) history and a physical examination remain the essential first steps in the diagnostic process.

Biochemical and hormonal screening aim at investigating serum electrolytes, renal function and the hypothalamic-pituitary-gonadal and hypothalamic-pituitary-adrenal axes. Ultrasound screening of kidneys and internal genitalia, as well as establishing genotypic sex, should be accomplished within 48 hours and complete the baseline diagnostic work-up of a child born with ambiguous genitalia.1 16 32 3346,XX disorders/differences of sex development (DSD) in the postnatal setting.

Conventional karyotyping can be useful. NGS, next-generation sequencing.Very recently, a European position paper has been published focusing on the genetic workup of DSD.16 It highlights the limitations and drawbacks of NGS-based tests, which include the chance of missing subtle structural variants such as CNVs and mosaicism and the fact that NGS cannot detect methylation defects or other epigenetic changes.16 28 31 Targeted DNA analysis is preferred in cases where hormonal investigations suggest a block in steroidogenesis (eg, 11-β-hydroxylase deficiency, 21-hydroxylase deficiency), or in the context of a specific clinical constellation such as the often coincidental finding of Müllerian structures in a boy with normal external genitalia or cryptorchidism, that is, persistent Müllerian duct syndrome.33 34 Alternative tests should also be considered depending on the available information. Sometimes, a simple mouth swab for FISH analysis can detect mosaic XY/X in a male with hypospadias or asymmetric gonadal development or in a female with little or no Turner syndrome stigmata and a normal male molecular karyotyping profile or peripheral blood karyotype.

Such targeted testing avoids incidental findings and is cheaper and faster than analysis of a large NGS-based panel, although the cost difference is rapidly declining.However, due to the genetic and phenotypic heterogeneity of DSD conditions, the most cost-effective next steps in the majority of cases are whole exome sequencing followed by panel analysis of genes involved in genital development and function or trio-analysis of a large gene panel (such as a Mendeliome).16 35–38 Pretest genetic counselling involves discussing what kind of information will be reported to patients or parents and the chance of detecting VUS, and the small risk of incidental findings when analysing a DSD panel should be mentioned. Laboratories also differ in what class of variants they report.39 In our experience, the fear of incidental findings is a major reason why some parents refrain from genetic testing.Timing of the DSD gene panel analysis is also important. While some patients or parents prefer that all diagnostic procedures be performed as soon as possible, others need time to reflect on the complex information related to more extensive genetic testing and on its possible consequences.

If parents or patients do not consent to panel-based genetic testing, analysis of specific genes, such as WT1, should be considered when appropriate in view of the clinical consequences if a mutation is present (eg, clinical surveillance of renal function and screening for Wilms’ tumour in the case of WT1 mutations). Genes that are more frequently involved in DSD (eg, SRY, NR5A1) and that match the specific clinical and hormonal features in a given patient could also be considered for sequencing. Targeted gene analysis may also be preferred in centres located in countries that do not have the resources or technical requirements to perform NGS panel-based genetic testing.

Alternatively, participation by these centres in international collaborative networks may allow them to outsource the molecular genetic workup abroad.Gene panels differ between centres and are regularly updated based on scientific progress. A comparison of DSD gene panels used in recent studies can be found at https://www.nature.com/articles/s41574-018-0010-8%23Sec46.15 The panels currently used at the coauthors’ institutions can be found on their respective websites. Given the pace of change, it is important to regularly consider repeating analysis in patients with an unexplained DSD, for example, when they transition into adult care or when they move from one centre to another.

This also applies to patients in whom a clinical diagnosis has never been genetically confirmed. Confusion may arise when the diagnosis cannot be confirmed or when a mutation is identified in a different gene, for example, NR5A1 in someone with a clinical diagnosis of CAIS that has other consequences for relatives. Hence, new genetic counselling should always accompany new diagnostic endeavours.Class 3 variants and histopathological examinationsThe rapidly evolving diagnostic possibilities raise new questions.

What do laboratories report?. How should we deal with the frequent findings of mainly unique VUS or class 3 variants (ACMG recommendation) in the many different DSD-related genes in the diagnostic setting?. Reporting VUS can be a source of uncertainty for parents, but not reporting these variants precludes further investigations to determine their possible pathogenicity.

It can also be difficult to prove variant pathogenicity, both on gene-level and variant-level.39 Moreover, given the gonad-specific expression of some genes and the variable phenotypic spectrum and reduced penetrance, segregation analysis is not always informative. A class 3 variant that does not fit the clinical presentation may be unrelated to the observed phenotype, but it could also represent a newly emerging phenotype. This was recently demonstrated by the identification of the NR5A1 mutation, R92W, in individuals with 46,XX testicular and ovotesticular DSD.40 This gene had previously been associated with 46,XY DSD.

In diagnostic laboratories, there is usually no capacity or expertise to conduct large-scale functional studies to determine pathogenicity of these unique class 3 VUS in the different genes involved in DSD. Functional validation of variants identified in novel genes may be more attractive in a research context. However, for individual families with VUS in well-established DSD genes such as AR or HSD17B3, functional analysis may provide a confirmed diagnosis that implies for relatives the option of undergoing their own DNA analysis and estimating the genetic risk of their own future offspring.

This makes genetic follow-up important in these cases and demonstrates the usefulness of international databases and networks and the centralisation of functional studies of genetic variants in order to reduce costs and maximise expertise.The same is true for histopathological description, germ-cell tumour risk assessment in specific forms of DSD and classification of gonadal samples. Germ-cell tumour risk is related to the type of DSD (among other factors), but it is impossible to make risk estimates in individual cases.41–44 Gonadectomy may be indicated in cases with high-risk dysgenetic abdominal gonads that cannot be brought into a stable superficial (ie, inguinal, labioscrotal) position that allows clinical or radiological surveillance, or to avoid virilisation due to 5-alpha reductase deficiency in a 46,XY girl with a stable female gender identity.45 Pathological examination of DSD gonads requires specific expertise. For example, the differentiation between benign germ cell abnormalities, such as delayed maturation and (pre)malignant development of germ cells, is crucial for clinical management but can be very troublesome.46 Centralised pathological examination of gonadal biopsy and gonadectomy samples in one centre, or a restricted number of centres, on a national scale can help to overcome the problem of non-uniform classification and has proven feasible in the Netherlands and Belgium.

We therefore believe that uniform assessment and classification of gonadal differentiation patterns should also be addressed in guidelines on DSD management.International databases of gonadal tissues are crucial for learning more about the risk of malignancy in different forms of DSD, but they are only reliable if uniform criteria for histological classification are strictly applied.46 These criteria could be incorporated in many existing networks such as the I-DSD consortium, the Disorders of Sex Development Translational Research Network, the European Reference Network on Urogenital Diseases (eUROGEN), the EndoERN and COST actions.15–17 47Communication at the transition from paediatric to adult carePaediatric and adult teams need to collaborate closely to facilitate a well-organised transition from paediatric to adult specialist care.15 48–50 Both teams need to exchange information optimally and should consider transition as a longitudinal process rather than a fixed moment in time. Age-appropriate information is key at all ages, and an overview of topics to be discussed at each stage is described by Cools et al.15 Table 1 shows an example of how transition can be organised.View this table:Table 1 Example of transition table as used in the DSD clinic of the Erasmus Medical CenterPsychological support and the continued provision of information remains important for individuals with a DSD at all ages.15 22 In addition to the information given by the DSD team members, families and patients can benefit from resources such as support groups and information available on the internet.47 Information available online should be checked for accuracy and completeness when referring patients and parents to internet sites.Recommendations for future actionsMost guidelines and articles on the diagnosis and management of DSD are aimed at specialists and are only published in specialist journals or on websites for endocrinologists, urologists or geneticists. Yet there is a need for guidelines directed towards first-line and second-line healthcare workers that summarise the recommendations about the first crucial steps in the management of DSD.

These should be published in widely available general medical journals and online, along with a national list of DSD centres. Furthermore, DSD (expert) centres should provide continuous education to all those who may be involved in the identification of individuals with a DSD in order to enable these healthcare professionals to recognise atypical genitalia, to promptly refer individuals who have a DSD and to inform the patient and parents about this and subsequent diagnostic procedures.As DSD continues to be a rare condition, it will take time to evaluate the effects of having such a guideline on the preparedness of first-line and second-line healthcare workers to recognise DSD conditions. One way to evaluate this might be the development and use of questionnaires asking patients, carers and families and referring physicians how satisfied they were with the initial medical consultation and referral and what could be improved.

A helpful addition to existing international databases that collect information on genetic variations would be a list of centres that offer suitable functional studies for certain genes, ideally covering the most frequently mutated genes (at minimum).Patient organisations can also play an important role in informing patients about newly available diagnostic or therapeutic strategies and options, and their influence and specific role has now been recognised and discussed in several publications.17 47 However, it should be kept in mind that these organisations do not represent all patients, as a substantial number of patients and parents are not member of such an organisation.Professionals have to provide optimal medical care based on well-established evidence, or at least on broad consensus. Yet not everything can be regulated by recommendations and guidelines. Options, ideas and wishes should be openly discussed between professionals, patients and families within their confidential relationship.

This will enable highly individualised holistic care tailored to the patient’s needs and expectations. Once they are well-informed of all available options, parents and/or patients can choose what they consider the optimal care for their children or themselves.15 16ConclusionThe Dutch-Flemish guideline uniquely addresses some topics that are under-represented in the literature, thus adding some key aspects to those addressed in recent consensus papers and guidelines.15–17 33 47As more children with a DSD are now being identified prenatally, and the literature on prenatal diagnosis of DSD remains scarce,20 21 we propose a prenatal diagnostic algorithm and emphasise the importance of having a prenatal specialist involved in or collaborating with DSD (expert) centres.We also stress that good communication between all involved parties is essential. Professionals should be well informed about protocols and communication.

Collaboration between centres is necessary to optimise aspects of care such as uniform interpretation of gonadal pathology and functional testing of class 3 variants found by genetic testing. Guidelines can provide a framework within which individualised patient care should be discussed with all stakeholders.AcknowledgmentsThe authors would like to thank the colleagues of the DSD teams for their input in and critical reading of the Dutch-Flemish guideline.

Three of the authors of this publication are members of the European Reference Network for rare endocrine diseases—Project ID 739543.IntroductionEndometrial cancer is the most common gynaecological malignancy in the developed world.1 Its incidence has risen over the last two decades as a consequence of the ageing population, fewer hysterectomies for benign disease and the obesity epidemic. In the USA, it is estimated that women have a 1 in 35 lifetime risk of endometrial cancer, and in contrast to cancers of most other sites, cancer-specific mortality has risen by approximately 2% every year since 2008 related to the rapidly rising incidence.2Endometrial cancer has traditionally been classified into type I and type II based on morphology.3 The more common subtype, type I, is mostly comprised of endometrioid tumours and is oestrogen-driven, arises from a hyperplastic endometrium, presents at an early stage and has an excellent 5 year survival rate.4 By contrast, type II includes non-endometrioid tumours, specifically serous, carcinosarcoma and clear cell subtypes, which are biologically aggressive tumours with a poor prognosis that are often diagnosed at an advanced stage.5 Recent efforts have focused on a molecular classification system for more accurate categorisation of endometrial tumours into four groups with distinct prognostic profiles.6 7The majority of endometrial cancers arise through the interplay of familial, genetic and lifestyle factors.

Two inherited cancer predisposition syndromes, Lynch syndrome and the much rarer Cowden syndrome, substantially increase the lifetime risk of endometrial cancer, but these only account for around 3–5% of cases.8–10 Having first or second degree relative(s) with endometrial or colorectal cancer increases endometrial cancer risk, although a large European twin study failed to demonstrate a strong heritable link.11 The authors failed to show that there was greater concordance in monozygotic than dizygotic twins, but the study was based on relatively small numbers of endometrial cancers. Lu and colleagues reported an association between common single nucleotide polymorphisms (SNPs) and endometrial cancer risk, revealing the potential role of SNPs in explaining part of the risk in both the familial and general populations.12 Thus far, many SNPs have been reported to modify susceptibility to endometrial cancer. However, much of this work predated genome wide association studies and is of variable quality.

Understanding genetic predisposition to endometrial cancer could facilitate personalised risk assessment with a view to targeted prevention and screening interventions.13 This emerged as the most important unanswered research question in endometrial cancer according to patients, carers and healthcare professionals in our recently completed James Lind Womb Cancer Alliance Priority Setting Partnership.14 It would be particularly useful for non-endometrioid endometrial cancers, for which advancing age is so far the only predictor.15We therefore conducted a comprehensive systematic review of the literature to provide an overview of the relationship between SNPs and endometrial cancer risk. We compiled a list of the most robust endometrial cancer-associated SNPs. We assessed the applicability of this panel of SNPs with a theoretical polygenic risk score (PRS) calculation.

We also critically appraised the meta-analyses investigating the most frequently reported SNPs in MDM2. Finally, we described all SNPs reported within genes and pathways that are likely involved in endometrial carcinogenesis and metastasis.MethodsOur systematic review follows the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) collaboration 2009 recommendations. The registered protocol is available through PROSPERO (CRD42018091907).16Search strategyWe searched Embase, MEDLINE and Cumulative Index to Nursing and Allied Health Literature (CINAHL) databases via the Healthcare Databases Advanced Search (HDAS) platform, from 2007 to 2018, to identify studies reporting associations between polymorphisms and endometrial cancer risk.

Key words including MeSH (Medical Subject Heading) terms and free-text words were searched in both titles and abstracts. The following terms were used. €œendomet*”,“uter*”, “womb”, “cancer(s)”, “neoplasm(s)”, “endometrium tumour”, “carcinoma”, “adenosarcoma”, “clear cell carcinoma”, “carcinosarcoma”, “SNP”, “single nucleotide polymorphism”, “GWAS”, and “genome-wide association study/ies”.

No other restrictions were applied. The search was repeated with time restrictions between 2018 and June 2019 to capture any recent publications.Eligibility criteriaStudies were selected for full-text evaluation if they were primary articles investigating a relationship between endometrial cancer and SNPs. Study outcome was either the increased or decreased risk of endometrial cancer relative to controls reported as an odds ratio (OR) with corresponding 95% confidence intervals (95% CIs).Study selectionThree independent reviewers screened all articles uploaded to a screening spreadsheet developed by Helena VonVille.17 Disagreements were resolved by discussion.

Chronbach’s α score was calculated between reviewers and indicated high consistency at 0.92. Case–control, prospective and retrospective studies, genome-wide association studies (GWAS), and both discovery and validation studies were selected for full-text evaluation. Non-English articles, editorials, conference abstracts and proceedings, letters and correspondence, case reports and review articles were excluded.Candidate-gene studies with at least 100 women and GWAS with at least 1000 women in the case arm were selected to ensure reliability of the results, as explained by Spencer et al.18 To construct a panel of up to 30 SNPs with the strongest evidence of association, those with the strongest p values were selected.

For the purpose of an SNP panel, articles utilising broad European or multi-ethnic cohorts were selected. Where overlapping populations were identified, the most comprehensive study was included.Data extraction and synthesisFor each study, the following data were extracted. SNP ID, nearby gene(s)/chromosome location, OR (95% CI), p value, minor or effect allele frequency (MAF/EAF), EA (effect allele) and OA (other allele), adjustment, ethnicity and ancestry, number of cases and controls, endometrial cancer type, and study type including discovery or validation study and meta-analysis.

For risk estimates, a preference towards most adjusted results was applied. For candidate-gene studies, a standard p value of<0.05 was applied and for GWAS a p value of <5×10-8, indicating genome-wide significance, was accepted as statistically significant. However, due to the limited number of SNPs with p values reaching genome-wide significance, this threshold was then lowered to <1×10-5, allowing for marginally significant SNPs to be included.

As shown by Mavaddat et al, for breast cancer, SNPs that fall below genome-wide significance may still be useful for generating a PRS and improving the models.19We estimated the potential value of a PRS based on the most significant SNPs by comparing the predicted risk for a woman with a risk score in the top 1% of the distribution to the mean predicted risk. Per-allele ORs and MAFs were taken from the publications and standard errors (SEs) for the lnORs were derived from published 95% CIs. The PRS was assumed to have a Normal distribution, with mean 2∑βipI and SE, σ, equal to √2∑βi2pI(1−pi), according to the binomial distribution, where the summation is over all SNPs in the risk score.

Hence the relative risk (RR) comparing the top 1% of the distribution to the mean is given by exp(Z0.01σ), where Z is the inverse of the standard normal cumulative distribution.ResultsThe flow chart of study selection is illustrated in figure 1. In total, 453 text articles were evaluated and, of those, 149 articles met our inclusion criteria. One study was excluded from table 1, for having an Asian-only population, as this would make it harder to compare with the rest of the results which were all either multi-ethnic or Caucasian cohorts, as stated in our inclusion criteria for the SNP panel.20 Any SNPs without 95% CIs were also excluded from any downstream analysis.

Additionally, SNPs in linkage disequilibrium (r2 >0.2) with each other were examined, and of those in linkage disequilibrium, the SNP with strongest association was reported. Per allele ORs were used unless stated otherwise.View this table:Table 1 List of top SNPs most likely to contribute to endometrial cancer risk identified through systematic review of recent literature21–25Study selection flow diagram. *Reasons.

Doi:10.1371/journal.pmed1000097.Top SNPs associated with endometrial cancer riskFollowing careful interpretation of the data, 24 independent SNPs with the lowest p values that showed the strongest association with endometrial cancer were obtained (table 1).21–25 These SNPs are located in or around genes coding for transcription factors, cell growth and apoptosis regulators, and enzymes involved in the steroidogenesis pathway. All the SNPs presented here were reported on the basis of a GWAS or in one case, an exome-wide association study, and hence no SNPs from candidate-gene studies made it to the list. This is partly due to the nature of larger GWAS providing more comprehensive and powered results as opposed to candidate gene studies.

Additionally, a vast majority of SNPs reported by candidate-gene studies were later refuted by large-scale GWAS such as in the case of TERT and MDM2 variants.26 27 The exception to this is the CYP19 gene, where candidate-gene studies reported an association between variants in this gene with endometrial cancer in both Asian and broad European populations, and this association was more recently confirmed by large-scale GWAS.21 28–30 Moreover, a recent article authored by O’Mara and colleagues reviewed the GWAS that identified most of the currently known SNPs associated with endometrial cancer.31Most of the studies represented in table 1 are GWAS and the majority of these involved broad European populations. Those having a multi-ethnic cohort also consisted primarily of broad European populations. Only four of the variants in table 1 are located in coding regions of a gene, or in regulatory flanking regions around the gene.

Thus, most of these variants would not be expected to cause any functional effects on the gene or the resulting protein. An eQTL search using GTEx Portal showed that some of the SNPs are significantly associated (p<0.05) with modified transcription levels of the respective genes in various tissues such as prostate (rs11263761), thyroid (rs9668337), pituitary (rs2747716), breast mammary (rs882380) and testicular (rs2498794) tissue, as summarised in table 2.View this table:Table 2 List of eQTL hits for the selected panel of SNPsThe only variant for which there was an indication of a specific association with non-endometrioid endometrial cancer was rs148261157 near the BCL11A gene. The A allele of this SNP had a moderately higher association in the non-endometrioid arm (OR 1.64, 95% CI 1.32 to 2.04.

P=9.6×10-6) compared with the endometrioid arm (OR 1.25, 95% CI 1.14 to 1.38. P=4.7×10-6).21Oestrogen receptors α and β encoded by ESR1 and ESR2, respectively, have been extensively studied due to the assumed role of oestrogens in the development of endometrial cancer. O’Mara et al reported a lead SNP (rs79575945) in the ESR1 region that was associated with endometrial cancer (p=1.86×10-5).24 However, this SNP did not reach genome-wide significance in a more recent larger GWAS.21 No statistically significant associations have been reported between endometrial cancer and SNPs in the ESR2 gene region.AKT is an oncogene linked to endometrial carcinogenesis.

It is involved in the PI3K/AKT/mTOR pro-proliferative signalling pathway to inactivate apoptosis and allow cell survival. The A allele of rs2494737 and G allele of rs2498796 were reported to be associated with increased and decreased risk of endometrial cancer in 2016, respectively.22 30 However, this association was not replicated in a larger GWAS in 2018.21 Nevertheless, given the previous strong indications, and biological basis that could explain endometrial carcinogenesis, we decided to include an AKT1 variant (rs2498794) in our results.PTEN is a multi-functional tumour suppressor gene that regulates the AKT/PKB signalling pathway and is commonly mutated in many cancers including endometrial cancer.32 Loss-of-function germline mutations in PTEN are responsible for Cowden syndrome, which exerts a lifetime risk of endometrial cancer of up to 28%.9 Lacey and colleagues studied SNPs in the PTEN gene region. However, none showed significant differences in frequency between 447 endometrial cancer cases and 439 controls of European ancestry.33KRAS mutations are known to be present in endometrial cancer.

These can be activated by high levels of KLF5 (transcriptional activator). Three SNPs have been identified in or around KLF5 that are associated with endometrial cancer. The G allele of rs11841589 (OR 1.15, 95% CI 1.11 to 1.21.

P=4.83×10-11), the A allele of rs9600103 (OR 1.23, 95% CI 1.16 to 1.30. P=3.76×10-12) and C allele of rs7981863 (OR 1.16, 95% CI 1.12 to 1.20. P=2.70×10-17) have all been found to be associated with an increased likelihood of endometrial cancer in large European cohorts.21 30 34 It is worth noting that these SNPs are not independent, and hence they quite possibly tag the same causal variant.The MYC family of proto-oncogenes encode transcription factors that regulate cell proliferation, which can contribute to cancer development if dysregulated.

The recent GWAS by O’Mara et al reported three SNPs within the MYC region that reached genome-wide significance with conditional p values reaching at least 5×10–8.35To test the utility of these SNPs as predictive markers, we devised a theoretical PRS calculation using the log ORs and EAFs per SNP from the published data. The results were very encouraging with an RR of 3.16 for the top 1% versus the mean, using all the top SNPs presented in table 1 and 2.09 when using only the SNPs that reached genome-wide significance (including AKT1).Controversy surrounding MDM2 variant SNP309MDM2 negatively regulates tumour suppressor gene TP53, and as such, has been extensively studied in relation to its potential role in predisposition to endometrial cancer. Our search identified six original studies of the association between MDM2 SNP rs2279744 (also referred to as SNP309) and endometrial cancer, all of which found a statistically significant increased risk per copy of the G allele.

Two more original studies were identified through our full-text evaluation. However, these were not included here as they did not meet our inclusion criteria—one due to small sample size, the other due to studying rs2279744 status dependent on another SNP.36 37 Even so, the two studies were described in multiple meta-analyses that are listed in table 3. Different permutations of these eight original studies appear in at least eight published meta-analyses.

However, even the largest meta-analysis contained <2000 cases (table 3)38View this table:Table 3 Characteristics of studies that examined MDM2 SNP rs2279744In comparison, a GWAS including nearly 13 000 cases found no evidence of an association with OR and corresponding 95% CI of 1.00 (0.97 to 1.03) and a p value of 0.93 (personal communication).21 Nevertheless, we cannot completely rule out a role for MDM2 variants in endometrial cancer predisposition as the candidate-gene studies reported larger effects in Asians, whereas the GWAS primarily contained participants of European ancestry. There is also some suggestion that the SNP309 variant is in linkage disequilibrium with another variant, SNP285, which confers an opposite effect.It is worth noting that the SNP285C/SNP309G haplotype frequency was observed in up to 8% of Europeans, thus requiring correction for the confounding effect of SNP285C in European studies.39 However, aside from one study conducted by Knappskog et al, no other study including the meta-analyses corrected for the confounding effect of SNP285.40 Among the studies presented in table 3, Knappskog et al (2012) reported that after correcting for SNP285, the OR for association of this haplotype with endometrial cancer was much lower, though still significant. Unfortunately, the meta-analyses which synthesised Knappskog et al (2012), as part of their analysis, did not correct for SNP285C in the European-based studies they included.38 41 42 It is also concerning that two meta-analyses using the same primary articles failed to report the same result, in two instances.38 42–44DiscussionThis article represents the most comprehensive systematic review to date, regarding critical appraisal of the available evidence of common low-penetrance variants implicated in predisposition to endometrial cancer.

We have identified the most robust SNPs in the context of endometrial cancer risk. Of those, only 19 were significant at genome-wide level and a further five were considered marginally significant. The largest GWAS conducted in this field was the discovery- and meta-GWAS by O’Mara et al, which utilised 12 096 cases and 108 979 controls.21 Despite the inclusion of all published GWAS and around 5000 newly genotyped cases, the total number did not reach anywhere near what is currently available for other common cancers such as breast cancer.

For instance, BCAC (Breast Cancer Association Consortium) stands at well over 200 000 individuals with more than half being cases, and resulted in identification of ~170 SNPs in relation to breast cancer.19 45 A total of 313 SNPs including imputations were then used to derive a PRS for breast cancer.19 Therefore, further efforts should be directed to recruit more patients, with deep phenotypic clinical data to allow for relevant adjustments and subgroup analyses to be conducted for better precision.A recent pre-print study by Zhang and colleagues examined the polygenicity and potential for SNP-based risk prediction for 14 common cancers, including endometrial cancer, using available summary-level data from European-ancestry datasets.46 They estimated that there are just over 1000 independent endometrial cancer susceptibility SNPs, and that a PRS comprising all such SNPs would have an area under the receiver-operator curve of 0.64, similar to that predicted for ovarian cancer, but lower than that for the other cancers in the study. The modelling in the paper suggests that an endometrial cancer GWAS double the size of the current largest study would be able to identify susceptibility SNPs together explaining 40% of the genetic variance, but that in order to explain 75% of the genetic variance it would be necessary to have a GWAS comprising close to 150 000 cases and controls, far in excess of what is currently feasible.We found that the literature consists mainly of candidate-gene studies with small sample sizes, meta-analyses reporting conflicting results despite using the same set of primary articles, and multiple reports of significant SNPs that have not been validated by any larger GWAS. The candidate-gene studies were indeed the most useful and cheaper technique available until the mid to late 2000s.

However, a lack of reproducibility (particularly due to population stratification and reporting bias), uncertainty of reported associations, and considerably high false discovery rates make these studies much less appropriate in the post-GWAS era. Unlike the candidate-gene approach, GWAS do not require prior knowledge, selection of genes or SNPs, and provide vast amounts of data. Furthermore, both the genotyping process and data analysis phases have become cheaper, the latter particularly due to faster and open-access pre-phasing and imputation tools being made available.It is clear from table 1 that some SNPs were reported with wide 95% CI, which can be directly attributed to small sample sizes particularly when restricting the cases to non-endometrioid histology only, low EAF or poor imputation quality.

Thus, these should be interpreted with caution. Additionally, most of the SNPs reported by candidate-gene studies were not detected by the largest GWAS to date conducted by O’Mara et al.21 However, this does not necessarily mean that the possibility of those SNPs being relevant should be completely dismissed. Moreover, meta-analyses were attempted for other variants.

However, these showed no statistically significant association and many presented with high heterogeneity between the respective studies (data not shown). Furthermore, as many studies utilised the same set of cases and/or controls, conducting a meta-analysis was not possible for a good number of SNPs. It is therefore unequivocal that the literature is crowded with numerous small candidate-gene studies and conflicting data.

This makes it particularly hard to detect novel SNPs and conduct meaningful meta-analyses.We found convincing evidence for 19 variants that indicated the strongest association with endometrial cancer, as shown in table 1. The associations between endometrial cancer and variants in or around HNF1B, CYP19A1, SOX4, MYC, KLF and EIF2AK found in earlier GWAS were then replicated in the latest and largest GWAS. These SNPs showed promising potential in a theoretical PRS we devised based on published data.

Using all 24 or genome-wide significant SNPs only, women with a PRS in the top 1% of the distribution would be predicted to have a risk of endometrial cancer 3.16 and 2.09 times higher than the mean risk, respectively.However, the importance of these variants and relevance of the proximate genes in a functional or biological context is challenging to evaluate. Long distance promoter regulation by enhancers may disguise the genuine target gene. In addition, enhancers often do not loop to the nearest gene, further complicating the relevance of nearby gene(s) to a GWAS hit.

In order to elucidate biologically relevant candidate target genes in endometrial cancer, O’Mara et al looked into promoter-associated chromatin looping using a modern HiChIP approach.47 The authors utilised normal and tumoural endometrial cell lines for this analysis which showed significant enrichment for endometrial cancer heritability, with 103 candidate target genes identified across the 13 risk loci identified by the largest ECAC GWAS. Notable genes identified here were CDKN2A and WT1, and their antisense counterparts. The former was reported to be nearby of rs1679014 and the latter of rs10835920, as shown in table 1.

Moreover, of the 36 candidate target genes, 17 were found to be downregulated while 19 were upregulated in endometrial tumours.The authors also investigated overlap between the 13 endometrial cancer risk loci and top eQTL variants for each target gene.47 In whole blood, of the two particular lead SNPs, rs8822380 at 17q21.32 was a top eQTL for SNX11 and HOXB2, whereas rs937213 at 15q15.1 was a top eQTL for SRP14. In endometrial tumour, rs7579014 at 2p16.1 was found to be a top eQTL for BCL11A. This is particularly interesting because BCL11A was the only nearby/candidate gene that had a GWAS association reported in both endometrioid and non-endometrioid subtypes.

The study looked at protein–protein interactions between endometrial cancer drivers and candidate target gene products. Significant interactions were observed with TP53 (most significant), AKT, PTEN, ESR1 and KRAS, among others. Finally, when 103 target candidate genes and 387 proteins were combined together, 462 pathways were found to be significantly enriched.

Many of these are related to gene regulation, cancer, obesity, insulinaemia and oestrogen exposure. This study clearly showed a potential biological relevance for some of the SNPs reported by ECAC GWAS in 2018.Most of the larger included studies used cohorts primarily composed of women of broad European descent. Hence, there are negligible data available for other ethnicities, particularly African women.

This is compounded by the lack of reference genotype data available for comparative analysis, making it harder for research to be conducted in ethnicities other than Europeans. This poses a problem for developing risk prediction models that are equally valuable and predictive across populations. Thus, our results also are of limited applicability to non-European populations.Furthermore, considering that non-endometrioid cases comprise a small proportion (~20%) of all endometrial cancer cases, much larger cohort sizes are needed to detect any genuine signals for non-endometrioid tumours.

Most of the evaluated studies looked at either overall/mixed endometrial cancer subtypes or endometrioid histology, and those that looked at variant associations with non-endometrioid histology were unlikely to have enough power to detect any signal with statistical significance. This is particularly concerning because non-endometrioid subtypes are biologically aggressive tumours with a much poorer prognosis that contribute disproportionately to mortality from endometrial cancer. It is particularly important that attempts to improve early detection and prevention of endometrial cancer focus primarily on improving outcomes from these subtypes.

It is also worth noting that, despite the current shift towards a molecular classification of endometrial cancer, most studies used the overarching classical Bokhman’s classification system, type I versus type II, or no histological classification system at all. Therefore, it is important to create and follow a standardised and comprehensive classification system for reporting tumour subtypes for future studies.This study compiled and presented available information for an extensively studied, yet unproven in large datasets, SNP309 variant in MDM2. Currently, there is no convincing evidence for an association between this variant and endometrial cancer risk.

Additionally, of all the studies, only one accounted for the opposing effect of a nearby variant SNP285 in their analyses. Thus, we conclude that until confirmed by a sufficiently large GWAS, this variant should not be considered significant in influencing the risk of endometrial cancer and therefore not included in a PRS. This is also true for the majority of the SNPs reported in candidate-gene studies, as the numbers fall far short of being able to detect genuine signals.This systematic review presents the most up-to-date evidence for endometrial cancer susceptibility variants, emphasising the need for further large-scale studies to identify more variants of importance, and validation of these associations.

Until data from larger and more diverse cohorts are available, the top 24 SNPs presented here are the most robust common genetic variants that affect endometrial cancer risk. The multiplicative effects of these SNPs could be used in a PRS to allow personalised risk prediction models to be developed for targeted screening and prevention interventions for women at greatest risk of endometrial cancer..
