BACKGROUND It has been reported that polymorphisms in the estrogen receptor (ER)-α gene (ESR1) may be associated with reproductive patterns of women. This study was performed to investigate whether the genetic polymorphisms of the ER-α gene are associated with idiopathic premature ovarian failure (POF) in a Korean population. METHODS The subjects were 126 idiopathic POF patients and 221 post-menopausal controls recruited from university hospitals between 1999 and 2004. Genotyping was performed by MGB primer/probe Taqman assay. Haplotypes were deduced by using the Haploview version 4.1. Bonferroni correction was applied for the correction of multiple testing. RESULTS There was no significant difference in the allele distribution of the ER-α gene (TA)n repeats between the POF and the control group. For the PvuII polymorphism, the POF group showed a higher frequency of TT genotype compared with the controls (41.3 versus 26.3%, P = 0.004, 98.75% CI 1.8–28.2%). No significant difference was found in the distribution of the XbaI polymorphism between the POF and the control group. Haplotype analysis showed that the frequency of TA haplotype was significantly higher in the POF patients compared with the controls (64.7 versus 52.7%, P = 0.002, 98.75% CI 2.4–21.6%). CONCLUSIONS These findings suggest that the ER-α gene polymorphisms may be associated with idiopathic POF.
