Abstract

The aim of this research was a study of gene LEPR polymorphism rs1137101 role in diabetes mellitus 2 type development and his influences on the clinical and laboratory data, related to obesity for these patients. 103 patients are inspected, that had the clinically expressed complications. A control group was made by 100 practically healthy persons of corresponding age. The analysis of polymorphic DNA-loci was carried out by the method of polymerase chain reaction in real time (TaqMan® SNP Genotyping Assay). Results showed that allelic polymorphism of rs1137101 (223Gln>Arg) had been associated with diabetes mellitus 2 types development: allele Gln promotes, while allele Arg-reduces (OR=1.5; P=0.039) the risk of its development. Presence allele Gln for diabetic patients assists development of obesity and his displays, namely-to the higher values of body mass index and HOMA-IR, and also to the greater leptin and triglycerides blood levels on a background reduction of high-density lipoproteides maintenance. The risk of developing obesity in these patients is increased by 1.8 times.
