Objective It has previously been reported that estrogen receptor-alpha (ERα) gene (ESR1: estrogen receptor 1) polymorphisms are associated with premature ovarian failure (POF). The aim of this study was to investigate whether these genetic polymorphisms of ESR1 are associated with POF in Serbian women. Methods A series of 197 POF cases matched with 547 fertile controls was recruited by the Institute for Endocrinology, Diabetes and Metabolic Disorders of Serbia between 2007 and 2010. Genomic DNA was extracted from saliva using Oragene® DNA sample collection kits. Two single-nucleotide polymorphisms (SNPs), PvuII and XbaI, in ESR1 were genotyped by dynamic allele-specific hybridization. Haplotype analyses were performed with the restriction fragment length polymorphism method. SNP and haplotype effects were analyzed by logistic regression models. Results No significant difference was found in the distribution of ESR1 PvuII and XbaI polymorphisms or haplotypes between the POF and control groups. Conclusion The two ESR1 SNPs, PvuII and XbaI, are not commonly associated with POF in Serbian women and may not contribute to the genetic basis of the condition. © 2014 International Menopause Society.

Objective: This study aimed to investigate the potential role of microsatellite polymorphisms of the estrogen receptor alpha gene (ESR1) TA repeat, estrogen receptor beta gene (ESR2) CA repeat, and androgen receptor gene (AR) CAG and GGN repeats among Serbian women with primary ovarian insufficiency (POI). These microsatellites have been reported to be associated with POI in different racial/ethnic populations. Methods: A cohort of 196 POI cases matched with 544 fertile controls was recruited by the Institute for Endocrinology, Diabetes and Metabolic Disorders of Serbia between 2007 and 2010. DNA was extracted from saliva. The four microsatellites were genotyped using a PCR-based assay to determine the repeat lengths. Results: POI patients carried shorter repeat lengths of ESR2 (CA) n than controls (P = 0.034), but the difference was small. ESR1 (TA) n was on the borderline of statistical differences between groups (P = 0.059). AR (CAG) n and (GGN) n showed no association with POI. Conclusions: We cautiously conclude that microsatellite polymorphisms of gonadal steroid receptor genes might contribute to the genetic basis of POI in Serbian women, but a larger-scale study and family-based studies are warranted to validate our findings even though the sample size in this study is larger than any previously published in this field. © 2018, © 2018 International Menopause Society.
