Abstract

Analysis of the genome-specific linkage disequilibrium patterns in certain populations is a highly promising approach to the identification of functional variants that underlie susceptibility to complex diseases. In the present study, the linkage disequilibrium patterns of the methylenetetrahydrofolate reductase gene (MTHFR) were examined in a group of patients with coronary atherosclerosis (coronary artery disease, CAD) and in a control sample from the Russian population. It was demonstrated that in the samples from one population, which were differentiated by the presence or absence of CAD, the MTHFR linkage disequilibrium patterns had similar features. Association of the MTHFR rs7533315 and rs2066462 polymorphisms with CAD was demonstrated. In addition, the evolution of the haplotypes and their role in the formation of CAD in the Russian population was reconstructed. The data on the association between genetic variability in the MTHFR locus and pathogenetically important indices of lipid metabolism were obtained. The high informativeness of the haplotype approach in case-control tests for associations with CAD was demonstrated.
