Abstract
PURPOSE To evaluate the association of single-nucleotide polymorphisms (SNPs) in the anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) genes with ovarian response and clinical pregnancy outcomes in women undergoing controlled ovarian hyperstimulation. METHODS In this prospective study, we genotyped AMH polymorphisms (c. -649 T > C, c. 146 T > G, c. 252 G > A, and c. 303 G > A) in 365 women and AMHR2 polymorphisms (c. -482 A > G, c. 622-6 C > T, c. 4952 G > A, c. 10 A > G) in 80 women undergoing controlled ovarian hyperstimulation for IVF. RESULTS Higher doses of exogenous FSH and lower numbers of preovulatory follicles were noted in women having AMH c. -649 T > C and AMH c. -146 T > G polymorphisms, respectively. Overall, we found that the presence of a polymorphic genotype (homozygous or heterozygous) at positions c. -649 T > C, c. 146 T > G, c. 252 G > A, and c. 303 G > A in the AMH gene was associated with higher doses of FSH for ovulation induction (p < 0.001). Interestingly, a higher live birth rate was noted in women with a homozygous polymorphic genotype for all four AMH SNPs investigated while none of the women showing a homozygous polymorphic genotype at all AMHR2 SNPs investigated in this study had a live birth. CONCLUSION Our results show that presence of AMHR2 SNPs (c. 482 A > G, c. 622-6 C > T, c. 4952 G > A, and c. 10 A > G) negatively correlate with live birth rate. However, these findings need to be validated by using larger sample size.

Chen D, Zhu X, Wu J. Can polymorphisms of AMH/AMHR2 affect ovarian stimulation outcomes? A systematic review and meta-analysis. J Ovarian Res 2020; 13:103. [PMID: 32887648 PMCID: PMC7487641 DOI: 10.1186/s13048-020-00699-4] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/31/2020] [Accepted: 08/03/2020] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Previous studies have investigated the effects of anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) polymorphisms on ovarian stimulation outcomes, but the results were inconsistent. METHODS We searched PubMed, Web of Science, Embase, and Cochrane Central Register of Controlled Trials databases for the literature used in this meta-analysis. The meta-analysis was performed with a random effects model with RevMan 5.3.5. Results were expressed as the relative risk (RR) for discrete data and the mean difference (MD) for continuous outcomes with a 95% confidence interval (CI). RESULTS Seven studies with 2078 participants were included. More metaphase II (MII) oocytes were retrieved in the T allele carrier of AMH (rs10407022) in the dominant model (MD: 1.20, 95% CI: 0.76 to 1.65, I2 = 0%, P < 0.00001), homozygote model (MD: 1.68, 95% CI: 0.35 to 3.01, I2 = 70%, P = 0.01) and heterogeneity model (MD: 1.20, 95% CI: 0.74 to 1.66, I2 = 0%, P < 0.00001). Oocytes retrieved from the Asian region in the TT carrier were significantly lesser than those in the GG/GT carrier in AMH (rs10407022) (MD: -1.41, 95% CI: - 1.75 to - 1.07, I2 = 0%). Differences in the stimulation duration, gonadotropin (Gn) dosage, and pregnancy rate were insignificant. CONCLUSIONS Our analysis indicated that the polymorphisms of AMH/AMHR2 could influence the ovarian stimulation outcomes. Prospective studies with a larger sample size and more rigorous design are needed in the future to further confirm these findings.

Is corifollitropin alfa effective in controlled ovarian stimulation among all poor ovarian responders? A retrospective comparative study. Gynecol Endocrinol 2019; 35:894-898.

Abstract
Several studies have compared the effectiveness of corifollitropin alfa versus daily gonadotropins in poor ovarian responders (PORs) undergoing controlled ovarian stimulation (COS), showing conflicting results in terms of IVF outcomes. Given the heterogeneity of patients included in the classification of POR according to 'Bologna criteria', the aim of this study was to evaluate the impact of corifollitropin alfa in two different categories of POR distinguished according to patients' antral follicle count (AFC). We retrospectively evaluated 104 infertile POR, split into two groups according to AFC (Group A ≤ 5; Group B > 5) and subgroups according to the ovarian stimulation regimen (corifollitropin alfa plus daily gonadotropins (Subgroup 1) versus daily gonadotropins alone (Subgroup 2)). Outcome measures were total oocytes, MII oocytes, total embryos, follicular output rate (FORT), implantation rate (IR), clinical pregnancy rate (CPR), miscarriage rate (MR), and live birth rate (LBR). Subgroup A1 experienced a lower number of total oocytes, MII oocytes, total embryos, and FORT (p < .05) in comparison to Subgroup A2, while no difference was found when comparing Subgroups B1 and B2. No difference was found between subgroups even in terms of IR, CPR, MR, and LBR. In conclusion, corifollitropin alfa may be as effective as daily gonadotropins in POR with AFC > 5 undergoing COS, while it might be inferior to daily gonadotropins in POR with AFC ≤ 5.

Abstract
The aim of this study was to examine the effects of single-nucleotide polymorphisms (SNPs) in the anti-Müllerian hormone (AMH) and AMH type II receptor (AMHRII) genes on in vitro fertilization (IVF) outcomes. In this prospective cohort study, we genotyped the AMH 146 T > G, AMHRII −482 A > G and AMHRII IVS1 +149 T > A variants in 635 women undergoing their first cycle of controlled ovarian stimulation for IVF. DNA was extracted from the peripheral blood of all participants, and the SNPs were genotyped by real-time polymerase chain reaction. The distributions, frequencies of genes, and correlation with clinical pregnancy of IVF were analyzed. The AMH 146 T > G G/G genotype in women was associated with a lower clinical pregnancy rate (T/T: 55.0%, T/G: 51.8%, G/G: 40.0%; p < 0.05). Women with the AMH 146 T > G GG genotype were half as likely to have a clinical pregnancy compared with women with TT genotypes (OR = 0.55, 95% CI: 0.34–0.88, p = 0.014). With multivariate analysis, the AMH 146 T > G GG genotype remains as a significant independent factor to predict clinical pregnancy (p = 0.014). No significant difference was found between AMHRII polymorphisms and clinical pregnancy outcomes of IVF. In conclusion, our results show that AMH 146 T > G seems to be a susceptibility biomarker capable of predicting IVF pregnancy outcomes. Further studies should focus on the mechanism of these associations and the inclusion of other ethnic populations to confirm the findings of this study.

Abstract
OBJECTIVE To determine the role of anti-Mullerian hormone (AMH) levels in predicting the response to clomiphene citrate (CC) therapy for ovulation induction in women with unexplained infertility. MATERIALS AND METHODS For this retrospective study, fifty consecutive patients who responded to CC were taken as Group 1, while fifty consecutive patients who failed to show adequate ovulatory response with CC were taken as Group 2. We compared the AMH levels of the two groups and receiver operating characteristic (ROC) curve was used to determine the threshold for AMH in predicting the ovulatory response to CC therapy. RESULTS Mean age, body mass index, luteinizing hormone, prolactin, and thyroid-stimulating hormone values were similar in the two groups. AMH and antral follicle count (AFC) values were higher in Group 1 than in Group 2 (p = 0.001 and p = 0.001, respectively). There was a statistically significant negative correlation between FSH and AFC (r = -0.339, p = 0.001), while AFC and AMH displayed a statistically significant positive correlation (r = 0.713 and p = 0.001). AMH values and AFC were found to be predictors of the adequate ovulatory response to CC. The area under the ROC curve was 0.86 vs 0.80, respectively. At an AFC cutoff value of 14, the sensitivity and specificity for prediction of ovulation were 68% and 80%, respectively. CONCLUSION The AMH and AFC cut-off values for the prediction of positive ovarian response to CC in patients with unexplained infertility were 2.78 ng/mL and 14, respectively. If further prospective and randomized studies confirm our results, these thresholds may be useful to predict successful ovulation induction and reduce the unresponsive cycles.

Abstract
PURPOSE The aim of this study was to investigate whether single nucleotide polymorphisms (SNPs) in selected genes, responsible for hormonal regulation of folliculogenesis, are associated with response to controlled ovarian hyperstimulation (COH) and clinical characteristics of women enrolled in in vitro fertilization (IVF) programs. METHODS In a cross-sectional study, 60 (IVF) patients underwent COH by using gonadotropin-releasing hormone (GnRH) antagonist and recombinant follicle-stimulating hormone (rFSH) protocol. Patients were classified into three groups: poor-responders (according to Bologna criteria), normo-responders (≤ 15 oocytes), and hyper-responders (> 15 oocytes). Genotyping of SNPs AMH rs10407022, AMHR rs3741664, FSHR rs1394205 and rs6166, and ESR1 rs2234693 was performed using high-resolution melting analysis (HRMA). Basal FSH (bFSH), estradiol (E2), and anti-Müllerian hormone (AMH) were measured by enzyme-linked immunosorbent assay (ELISA). RESULTS Patients with GG genotype of FSHR rs1394205 had significantly lower AMH level (P = 0.016) and required higher rFSH dose per oocyte compared to women with AA or AG genotype (P = 0.036). We also found higher frequency of GG genotype of FSHR rs1394205 in poor- (76.5%) than in hyper-responders (37.5%, P = 0.002). Patients with AA genotype of FSHR rs6166 had higher level of measured bFSH compared to those with AG or GG genotypes (P = 0.043). Women with GG genotype of AMHR rs3741664 required higher rFSH dose in comparison with patients carrying genotypes AA or AG (P = 0.028). CONCLUSIONS The GG genotype at position rs1394205 is associated with poor ovarian response to COH. Patients with this genotype may require higher doses of rFSH for ovulation induction.

Abstract
Controlled ovarian stimulation (COS) is crucial for optimizing in-vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) success. Multiple factors influence the ovarian response to COS, making predictions about oocyte yields not so straightforward. As a result, the ovarian response may be poor or suboptimal, or even excessive, all of which have negative consequences for the affected patient. There is a group of patients that present with a suboptimal response to COS despite normal biomarkers of ovarian reserve, such as AFC and AMH. These patients have a lower number of retrieved oocytes than what was expected based on their ovarian reserve, thus showing the inadequacy of using only the traditional ovarian reserve biomarkers to predict the ovarian response. Suboptimal response to COS might be related to ovarian sensitivity to exogenous gonadotropins modulated by genetic factors. The understanding of the gene polymorphisms related to reproductive function can help to improve the clinical management of this patient population and to explain some of the individual patient variability in response to COS. The development of a pharmacogenetic approach concerning COS in the context of assisted reproduction seems attractive as it might help to understand the relationship between genetic variants and ovarian response to exogenous gonadotropins. The patient's genetic profile could be used to select the most appropriate gonadotropin type, predict the optimal dosage for each drug, develop a cost-effective treatment plan, maximize the success rates, and lastly, decrease the time-to-pregnancy.

Abstract
OBJECTIVE To test the hypothesis that women with unexplained infertility demonstrate evidence of diminished ovarian reserve when compared with a population of community controls. DESIGN Cross-sectional study. SETTING Multicenter university-based clinical practices. PATIENT(S) Study participants included 277 healthy, normo-ovulatory female partners with rigorously defined unexplained infertility randomly selected from a multicenter trial (Assessment of Multiple Intrauterine Gestations from Ovarian Stimulation). Controls included 226 healthy, normo-ovulatory women not seeking treatment for fertility from a community-based cohort (Ovarian Aging study). INTERVENTION(S) Serum antimüllerian hormone (AMH) assay at a central laboratory, FSH, fasting serum metabolic testing, transvaginal ultrasonography for antral follicle counts (AFCs), anthropometric measurements. MAIN OUTCOME MEASURE(S) Average AMH, AFC, and AMH/AFC were compared between infertile and control women by age. Analyses of covariance compared these outcomes while controlling for confounders, including age, race, body mass index, smoking history, and study site. RESULT(S) In our models, AMH, AFC, and AMH/AFC ovarian reserve indices did not differ between infertile women and community-based controls, after controlling for age, race, body mass index, smoking history, and study site. CONCLUSION(S) Currently utilized predictors of ovarian reserve do not discriminate women with rigorously defined unexplained infertility from healthy community-based women of similar demographic characteristics. Contrary to our hypothesis, among women with FSH in the normal range (≤12 IU/L), women with unexplained infertility did not show evidence of decreased ovarian reserve as measured by AMH and AFC. Ovarian reserve markers in isolation may not serve as predictors of future fertility.

Abstract
PURPOSE The purpose of this paper is to determine whether there is a correlation between polymorphisms in the growth differentiation factor-9 (GDF-9) gene and anti-Müllerian hormone (AMH) gene and its receptor, AMHR2, and endometriosis-associated infertility. METHODS This is a case-control study to evaluate whether there is a correlation between polymorphisms in the GDF-9 gene (SNPs determined by direct sequencing), AMH gene, AMHR2 (both SNPs determined by genotyping using TaqMan Allelic Discrimination), and endometriosis-associated infertility. The study included 74 infertile women with endometriosis and 70 fertile women (tubal ligation) as a control group. RESULTS Patient age and the mean FSH levels were similar between the infertile with endometriosis and fertile without endometriosis groups. The frequency of genotypes between the groups for GDF-9 gene polymorphisms did not show statistical significance, nor did the AMHR2 gene polymorphism. However, the AMH gene polymorphism did show statistical significance, relating the polymorphic allele with infertility in endometriosis. CONCLUSIONS We demonstrate that an SNP in the AMH gene is associated with infertility in endometriosis, whereas several SNPs in the GDF-9 gene and the - 482A G SNP in the AMHR2 gene were found to be unrelated.

Are anti-Müllerian hormone and its receptor polymorphism associated with the hormonal condition of undescended testes? Adv Med Sci 2016; 61:288-292. [PMID: 27162065 DOI: 10.1016/j.advms.2016.03.004] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/25/2016] [Revised: 03/05/2016] [Accepted: 03/17/2016] [Indexed: 01/10/2023]
Abstract
PURPOSE Numerous genetic and endocrine factors are involved in the process of testicular descent, but only a few genetic causes have been reported in human. The aim of this study was to investigate the density and distribution of single nucleotide polymorphisms (SNPs) anti-Müllerian hormone (AMH) and AMHRII receptors in cryptorchid patients and determine potential hormone imbalance connected with undescended testes by assessing the levels of AMH, Insulin-like factor 3 (INSL3) and inhibin B. MATERIALS AND METHODS The serum hormone levels (AMH, INSL3 and inhibin B) were compared in the two groups - cryptorchidism (n=105) and control group (n=58). The frequency of AMHRII -482 A>G, AMHRII IVS 10+77 A>G, AMHRII IVS 5-6 C>T, and AMH Ile49Ser polymorphisms among cryptorchid boys were compared with the control group. RESULTS None of the hormones levels were different between the cryptorchid and the control groups. All cases of IVS 5-6 C>T homozygote and heterozygote mutation were accompanied by an IVS 10+77 A>G and 482 A>G homozygote and heterozygote mutation. Interestingly, in most cases of all four polymorphisms, homozygote recessive genotype was associated with cases of cryptorchidism. However, the groups of patients were too small to draw definite conclusions. CONCLUSION The AMHRII -482 A>G, AMHRII IVS 10+77 A>G, AMHRII IVS 5-6 C>T and AMH Ile49Ser genotypes should be determined in a much larger group of boys with cryptorchidism.

Abstract
The aim of the current study was to explore whether anti-Müllerian hormone receptor II (AMHRII) genetic variants influence the hormonal profile and the ovarian response to standard gonadotropin stimulation of women undergoing medically assisted reproduction. Three hundred in vitro fertilization or intracytoplasmic sperm injection patients constituted the study population, while 300 women with at least one spontaneous pregnancy participated as controls. The follicle-stimulating hormone (FSH), luteinizing hormone (LH), estradiol (E2) and AMH levels were determined at the third day of the menstrual cycle. AMHRII 10A > G (rs11170555), 1749C > T (rs2071558) and -482A > G (rs2002555) polymorphisms were genotyped. The follicle and oocyte numbers, the follicle size and the clinical pregnancies were recorded. Regarding the AMHRII 1749C > T polymorphism, 1749CT women presented with higher total follicle and small follicle numbers compared to 1749CC women (p = 0.04 and p = 0.01, respectively). Whereas, as concerns the -482A > G polymorphism, -482AG women were characterized by higher total follicle and small follicle numbers comparing with -482AA women (p = 0.07 and p = 0.004, respectively). Finally, -482AG women presented with increased FSH levels compared to -482AA women (p < 0.05). However, no associations of AMHRII gene polymorphisms with serum AMH levels or clinical pregnancy rates were observed. AMHRII 1749C > T and -482A > G genetic variants were associated with the ovarian response to standard gonadotropin stimulation, affecting mainly the follicular growth.

Abstract
Purpose Genetic variation may influence women’s response to ovarian stimulation therapy. The purpose of this study was to investigate any effects of genetic variants in the anti-Müllerian hormone (AMH) and AMH type II receptor genes on ovarian response/treatment outcomes and on current markers of ovarian reserve in individuals undergoing in vitro fertilisation (IVF) treatment. Methods In this prospective observational study, we genotyped the AMH c.146G>T, p.(Ile49Ser) and AMHR2 -482A>G variants in 603 unrelated women undergoing their first cycle of controlled ovarian stimulation for IVF and ICSI (intracytoplasmic sperm injection) using gonadotrophins at a tertiary referral centre for reproductive medicine. Pelvic ultrasound and blood hormone levels were taken on days 2–3 of the cycle. Genotypes were determined using TaqMan allelic discrimination assay. Regression analysis was performed to assess the relationship between the genotypes and the ovarian reserve markers (FSH, AMH, antral follicle count) and the early outcomes of response (number of oocytes retrieved and gonadotropin dose) as well as the treatment outcome (live birth). Results There were no significant associations between the variants AMH c.146G>T and AMHR2 -482A>G with ovarian response in terms of number of oocytes retrieved (p = 0.08 and p = 0.64, respectively), live births (p = 0.28 and p = 0.52) and/or markers of ovarian reserve. Conclusions Genotyping of the AMH c.146G>T and AMHR2 -482A>G polymorphisms does not provide additional useful information as a predictor of ovarian reserve or ovarian response and treatment outcomes.

Abstract
STUDY QUESTION Are mutations in NLRP2/7 (NACHT, LRR and PYD domains-containing protein 2/7) or KHDC3L (KH Domain Containing 3 Like) associated with recurrent pregnancy loss (RPL) or infertility? SUMMARY ANSWER We found no evidence for mutations in NLRP2/7 or KHDC3L in unexplained RPL or infertility. WHAT IS KNOWN ALREADY Mutations in NLRP7 and KHDC3L are known to cause biparental hydatidiform moles (BiHMs), a rare form of pregnancy loss. NLRP2, while not associated with the BiHM pathology, is known to cause recurrent Beckwith Weidemann Syndrome (BWS). STUDY DESIGN, SIZE, AND DURATION Ninety-four patients with well characterized, unexplained infertility were recruited over a 9-year period from three IVF clinics in Sweden. Blood samples from 24 patients with 3 or more consecutive miscarriages of unknown etiology were provided by the Recurrent Miscarriage Clinic at St Mary's Hospital, London, UK. PARTICIPANTS/MATERIALS, SETTING, METHODS Patients were recruited into both cohorts following extensive clinical studies. Genomic DNA was isolated from peripheral blood and subject to Sanger sequencing of NLRP2, NLRP7 and KHDC3L. Sequence electropherograms were analyzed by Sequencher v5.0 software and variants compared with those observed in the 1000 Genomes, single nucleotide polymorphism database (dbSNP) and HapMap databases. Functional effects of non-synonymous variants were predicted using Polyphen-2 and sorting intolerant from tolerant (SIFT). MAIN RESULTS AND THE ROLE OF CHANCE No disease-causing mutations were identified in NLRP2, NLRP7 and KHDC3L in our cohorts of unexplained infertility and RPL. LIMITATIONS, REASONS FOR CAUTION Due to the limited patient size, it is difficult to conclude if the low frequency single nucleotide polymorphisms observed in the present study are causative of the phenotype. The design of the present study therefore is only capable of detecting highly penetrant mutations. WIDER IMPLICATIONS OF THE FINDINGS The present study supports the hypothesis that mutations in NLRP7 and KHDC3L are specific for the BiHM phenotype and do not play a role in other adverse reproductive outcomes. Furthermore, to date, mutations in NLRP2 have only been associated with the imprinting disorder BWS in offspring and there is no evidence for a role in molar pregnancies, RPL or unexplained infertility.

Abstract
CONTEXT The polycystic ovary syndrome (PCOS) is a common and complex disease without a clear pattern of inheritance. Anti-Müllerian hormone (AMH) has an inhibitory effect on FSH-stimulated follicle growth. Serum AMH levels are higher in women with PCOS than in normo-ovulatory women. The elevated AMH levels may reflect abnormalities in AMH signaling. OBJECTIVE The purpose of this study was to evaluate the association of the anti-Müllerian hormone receptor 2 (AMHR2) -482 A>G polymorphism (rs2002555) with the pathophysiology of PCOS. DESIGN AMHR2 -482 A>G polymorphism genotyping were performed in a large cohort of women with PCOS and in a healthy control group. SETTING/SUBJECTS A total of 858 Caucasian Greek women with PCOS and 309 healthy control women were studied. INTERVENTIONS Genotyping and hormonal measurements were preformed. MAIN OUTCOME MEASURES Hormone levels in women with PCOS were analyzed. RESULTS The AMHR2 polymorphism was more common in women with PCOS than in control women (P = .026). Homozygous AMHR2 -482 A>G gene polymorphisms (GG) were associated with decreased levels of LH (P = .003) and lower LH to FSH ratios (P = .01) in women with PCOS, as well as with lower prolactin levels (P = .004). No other associations related to AMHR2 -482 A>G polymorphisms were observed in women with PCOS or control women. CONCLUSION In this study, the role of the AMHR2 -482 A>G gene polymorphism in the pathogenesis of PCOS was suggested by the association of the variant with PCOS risk. Thus, further research is needed to elucidate a possible association of the AMHR2 -482 A>G gene polymorphism with AMH signaling and impaired ovarian function and its clinical significance in women with PCOS.

Abstract
BACKGROUND To report on relationships among baseline serum anti-Müllerian hormone (AMH) measurements, blastocyst development and other selected embryology parameters observed in non-donor oocyte IVF cycles. METHODS Pre-treatment AMH was measured in patients undergoing IVF (n = 79) and retrospectively correlated to in vitro embryo development noted during culture. RESULTS Mean (+/- SD) age for study patients in this study group was 36.3 ± 4.0 (range = 28-45) yrs, and mean (+/- SD) terminal serum estradiol during IVF was 5929 +/- 4056 pmol/l. A moderate positive correlation (0.49; 95% CI 0.31 to 0.65) was noted between basal serum AMH and number of MII oocytes retrieved. Similarly, a moderate positive correlation (0.44) was observed between serum AMH and number of early cleavage-stage embryos (95% CI 0.24 to 0.61), suggesting a relationship between serum AMH and embryo development in IVF. Of note, serum AMH levels at baseline were significantly different for patients who did and did not undergo blastocyst transfer (15.6 vs. 10.9 pmol/l; p = 0.029). CONCLUSIONS While serum AMH has found increasing application as a predictor of ovarian reserve for patients prior to IVF, its roles to estimate in vitro embryo morphology and potential to advance to blastocyst stage have not been extensively investigated. These data suggest that baseline serum AMH determinations can help forecast blastocyst developmental during IVF. Serum AMH measured before treatment may assist patients, clinicians and embryologists as scheduling of embryo transfer is outlined. Additional studies are needed to confirm these correlations and to better define the role of baseline serum AMH level in the prediction of blastocyst formation.

Abstract
CONTEXT Timing of menopause is largely influenced by genetic factors. Because menopause occurs when the follicle pool in the ovaries has become exhausted, genes involved in primordial follicle recruitment can be considered as candidate genes for timing of menopause. OBJECTIVE The aim was to study the association of 23 tagging single nucleotide polymorphisms in five genes [Anti-Müllerian hormone (AMH), AMH type II receptor (AMHR2), bone morphogenetic protein 15 (BMP15), forkhead transcription factor L2 (FOXL2), and growth differentiation factor-9 (GDF9)] involved in recruitment of the primary follicle pool, including the AMHR2 gene, which has recently been associated with age at menopause. DESIGN We conducted a cross-sectional association study. SETTING AND PARTICIPANTS We studied a population-based sample of 3616 Dutch women with natural menopause. MAIN OUTCOME MEASURE We measured age at natural menopause. RESULTS Both studied AMHR2 tagging single nucleotide polymorphisms (rs2002555 and rs11170547) in the AMHR2 gene were associated with age at natural menopause in interaction with parity. Parous rs2002555 G/G carriers had menopause 1 yr later compared with A/A carriers (P = 0.01). For rs11170547, each minor allele (T) was associated with a 0.41-yr later onset of menopause in parous women (P = 0.01). Additionally, rs6521896 in BMP15 was associated with later menopause (β = 0.41; P = 0.007). Variants in the AMH, FOXL2, and GDF9 genes were not associated with timing of menopause. CONCLUSIONS The present study confirms an earlier finding that variation in the AMHR2 gene modifies the relation between parity and age at natural menopause. In combination with the association of BMP15 with menopausal age, we find that there is evidence that genes involved in primary follicle recruitment influence timing of menopause.

Abstract
High resolution melting is a new method of genotyping and variant scanning that can be seamlessly appended to PCR amplification. Limitations of genotyping by amplicon melting can be addressed by unlabeled probe or snapback primer analysis, all performed without labeled probes. High resolution melting can also be used to scan for rare sequence variants in large genes with multiple exons and is the focus of this article. With the simple addition of a heteroduplex-detecting dye before PCR, high resolution melting is performed without any additions, processing or separation steps. Heterozygous variants are identified by atypical melting curves of a different shape compared to wild-type homozygotes. Homozygous or hemizygous variants are detected by prior mixing with wild-type DNA. Design, optimization, and performance considerations for high resolution scanning assays are presented for rapid turnaround of gene scanning. Design concerns include primer selection and predicting melting profiles in silico. Optimization includes temperature gradient selection of the annealing temperature, random population screening for common variants, and batch preparation of primer plates with robotically deposited and dried primer pairs. Performance includes rapid DNA preparation, PCR, and scanning by high resolution melting that require, in total, only 3h when no variants are present. When variants are detected, they can be identified in an additional 3h by rapid cycle sequencing and capillary electrophoresis. For each step in the protocol, a general overview of principles is provided, followed by an in depth analysis of one example, scanning of CYBB, the gene that is mutated in X-linked chronic granulomatous disease.
