[Analysis of mitochondrial haplogroups in persons with subclinical atherosclerosis based on high-throughput mtDNA...

Genetic predisposition plays an important role among other risk factors in multifactorial socially significant diseases such as atherosclerosis and its clinical manifestations. This pilot study was aimed to identify the relationship between the type of mitochondrial haplogroup and the risk of subclinical atherosclerosis in humans. For accurate detection of mitochondrial haplogroups, high-throughput sequencing of the mitochondrial genome using the Roche 454 technology was carried out. The results have shown that in Russian population, the belonging to haplogroup H is associated with an increased risk of atherosclerosis, but belonging to haplogroups T and U--with reduced risk. The data obtained can be used to assess individual risk of atherosclerosis and for further studies on the role of mitochondrial genome mutations in the development of atherosclerosis and its clinical manifestations.
