АССОЦИАЦИЯ ПОЛИМОРФИЗМОВ Ser447Ter ГЕНА LPL И rs9939609 ГЕНА FTO С ОЖИРЕНИЕМ У ДЕТЕЙ И ПОДРОСТКОВ В ПОПУЛЯЦИИ РОСТОВА-НА-ДОНУ

Abstract

The aim of this study was to study the correlation between the Ser447ter (C-G) polymorphisms of the LPL gene and rs9939609 of the FTO gene and obesity in children and adolescents of the Rostov region (Russia). A case-control study examined the relationship between the rs9939609 polymorphisms of the FTO gene and Ser447Ter (S447X) of the LPL gene with obesity in 520 children and adolescents of both sexes aged 3 to 18 years: the main group consisted of 370 obese children and adolescents, and the control group - 150 children and adolescents without obesity. Genotyping of polymorphisms T / A rs9939609 of the FTO gene and C / G Ser447Ter of the LPL gene was performed using PCR- allele-specific primers. Polymorphisms of the FTO rs9939609 and LPL Ser447Ter genes in donor DNA samples were typed by the electrophoretic method using commercial test systems from the Litekh research and production com-pany (Russia). The relationship between the rs9939609 polymorphism of the FTO gene and obesity was revealed, differences (P<0.05) were established between the main and control groups in the frequency of occurrence of the AA genotype (P = 0.0079) and allele A (P = 0.005; OR 0.67; 95% CI 0.51–0.88) of the rs9939609 polymorphism of the FTO gene. Combinations of genotypes with increased and decreased risk of obesity in the child and adolescent population of Rostov-on-Don were determined. Antagonistic rela-tionships between the rs9939609 polymorphisms of the FTO gene and Ser447Ter of the LPL gene are shown. Using the MDR method, combinations of genotypes with an increased and decreased risk of obe-sity in the child and adolescent population of Rostov-on-Don were established.
