The Multiplex Genotyping Method for Single-Nucleotide Polymorphisms of Genes Associated with Obesity and Body Mass Index

Abstract

Obesity is one of the global health problems resulting in significant economic and social damage in both developed and developing countries. Overweight and obesity are key risk factors of diabetes and cardiovascular and oncological diseases that cause high morbidity and mortality. In the present paper, the method of multiplex genotyping of polymorphic variants of genes associated with obesity and variability of body mass index (BMI) was developed on the basis of multilocus PCR and MALDI-TOF mass spectrometry of DNA molecules. The frequencies of 51 single-nucleotide polymorphisms of obesity candidate genes in a population sample of Russians in Kemerovo were characterized. The results obtained were compared with the data for populations from the 1000 Genomes project. The association of markers rs12446632 of the LOC105371116 locus and rs16851483 of the RASA2 gene with BMI variability in the Russian population of Kemerovo was shown.
