Investigation of population characteristics of the frequencies of polymorphic variants of the vitamin D receptor gene in the population of Western Siberia

Abstract

The results of a study of the population frequencies of polymorphic variants of the VDR gene (FokI, rs2228570; BsmI, rs1544410) in populations of Tobolo-Irtysh Siberian Tatars and Shors are discussed. The material for the study was collected in the expeditions of the scientific groups of KemSMU of the Ministry of Health of the Russian Federation, MGNC, KemSU, Tobolsk Integrated Scientific Station of the UrB of RAS. The total sample size is 166 people. Genotyping was carried out by real-time PCR using TaqMan probes. Mathematical processing - using the STATISTICA 8.0 statistical software package and standard approaches of population genetics. The study showed that the population of Shorets (the area of settlement in the Tashtagolsky district of the Kemerovo region) they are characterized by lower frequencies of minor alleles of the VDR BsmI*A and FokI*C in comparison with the Tobolo-Irtysh Siberian Tatars (Tyumen, Yarkovsky, Yalutorovsky districts of the Tyumen region). In the studied groups, there is a deviation in the level of heterozygosity.
