Effect of estrogen receptor gene ESR1 polymorphism on development of premenstrual syndrome.

To identify risks of development of any disease is a priority of modern medicine. The aim of this study was to investigate the frequency of polymorphic variants of A-351G gene estrogen receptor ESR1 in patients with various forms of PMS. Molecular genetic analysis of ESR1 gene polymorphism in 50 women with PMS (25 women of them had edematous form of disease, 25 - neuropsychical, 25 - mild, 25 - severe form) was carried out. 25 women without diagnosis of PMS were examined as controls. The study A-351G polymorphism estrogen gene ESR1 showed no statistically significant differences in the frequency of distribution of genotypes and alleles between women with PMS and without this pathology. However, the frequency of GG genotype in women with severe PMS was significantly higher in 8.0 times compared with healthy women (χ2=4.87, p=0.03) and in women with edematous form of PMS - in 7.0 times (χ2=3.72, p=0.05). Thus, a polymorphic variant of A-351G gene ESR1 estrogen can be considered as a marker of PMS. Pathological variant GG genotype was significantly associated with the presence of edematous and severe forms of the disease.
