The purpose — to estimate the prevalence of rs2498796 polymorphism of the АКТ1 gene and reveal its association with the risk of endometrial hyperplasia. Material and methods. The study included 180 residents of the Republic of Tatarstan: 79 patients with endometrial hyperplasia, 101 women without endometrial pathology. Determination of rs2498796 polymorphism of the АКТ1 gene was carried out by the method of real time polymerase chain reaction. The study performed a χ2 test and evaluated the odds ratio. Results. The ratio of homozygous for the allele C (C/C), heterozygous (C/T) and homozygous for the allele T (T/T) rs2498796 of the AKT1 gene was in the main group 35 (44,3%), 30 (38%), and 14 (17,7%), in the control group – 46 (45,5%), 45 (44,6%), and 10 (9,9%) respectively. The frequency of the T allele and the C allele rs2498796 in women with endometrial polyps was comparable to that in the control group (χ2=0,81, р=0,37). Conclusion. Among 180 females of the Republic of Tatarstan included into the study, the associations of rs2498796 polymorphism of the АКТ1 gene with the risk of endometrial hyperplasia were not identified.
