A feature of human morphology, which is most often considered in connection with gene polymorphism, is excessive fat deposition. Obesity contributes to an increased risk of chronic diseases.
THE AIM OF THIS STUDY
Is to search for possible associations between the rs4680 polymorphism of the COMT gene and the morphofunctional characteristics of students in Russia and Transnistria.
MATERIALS AND METHODS
The data of genotyping (according to the COMT gene) and a comprehensive anthropological examination (18 morphological and functional indicators) of 451 volunteers aged 16—23 years were the materials for the study.
RESULTS
The study of the distribution of alleles in the examined youth sample showed the predominance of the G allele over the A allele (0.533 and 0.467, respectively), which is consistent with data from other researchers obtained from samples of Russian residents of Novosibirsk and Americans of European descent. According to the results of a multi-stage statistical analysis of anthropogenetic data, it was found that young men and women who are carriers of at least one A allele are not prone to reduced metabolic rate and increased body weight compared to holders of the G/G homozygous genotype. In turn, carriers of the G/G genotype are characterized by a deterioration in physical development: they have a lower proportion of the musculoskeletal component of body composition and a low rate of metabolic processes with increased body weight compared to individuals with the A/A or A/G genotype.
CONCLUSION
Statistically significant relationships were revealed between the the COMT gene rs4680 polymorphism and the characteristics of the males and females body composition. The results are consistent with some data from other researchers who find correlations of the G/G genotype with a predisposition to obesity and type 2 diabetes mellitus, as well as to high-fat foods intake.
