RESUMO
Premenstrual syndrome (PMS) is a common problem of women in reproductive age. Genetic aspects of this pathology are not completely clear. The aim of the article is devoted to the study of the frequency of ID polymorphism of angiotensin-converting enzyme gene ACE in patients with premenstrual syndrome. The object of the study were 50 women in reproductive age with the diagnosis of PMS, 25 of them had mild form of the disease, 25 - severe one. 25 persons without PMS were controls. Polymerase chain reaction was used to study ACE gene polymorphism. We determined an equal distribution of ACE gene genotypes between women with PMS and without this pathology (DD genotype was established in 24% of controls and 30% women with PMS, ID genotype - 60% and 46% respectively, II genotype - 16% and 24%). However, DD genotype was found in 2.17 times more often in patients with severe form of the disease (52%) compared to healthy persons. Thus, women with DD genotype of ACE gene have the tendency to the development of severe PMS (χ2=3.06, p=0.08; OR=3.43, 95% CI 1.02-11.47, p=0.045).
