description Mitochondrial DNA (mtDNA) polymorphism makes a certain contribution to the formation of a genetic risk of multiple sclerosis (MS).Objective: to analyze the frequency of mtDNA variants in patients with MS and control individuals in the Russian population. A similar study was conducted for the first time.Patients and methods. The polymorphism of mtDNA was studied in the Russian population: in 283 unrelated patients with relapsing-remitting MS and in 290 unrelated healthy controls matched for gender and age.Results and discussion. The frequency of haplogroup J in the patients with MS was twice higher than that in the control group (p=0.0055) (odds ratio (OR) 2.00; 95% confidence interval (CI). 1.21–3.41). This association was mostly observed in women (p=0.0083) (OR 2.20; 95% CI, 1.19–4.03). There was also a significant association of the A allele of MT-ND5 (m. 13708G>A) with MS (p=0.03) (OR 1.89; 95% CI 1.11–3.32). Sex stratification showed that the association with MS was significant only in women (p=0.009; OR, 2.52; 95% CI, 1.29–5.14). Further investigations will aim to analyze mtDNA variability (at the level of individual polymorphisms, haplogroups, and whole genome) in patients with relapsing-remitting MS and in those with primary progressive MS versus healthy individuals and patients with relapsing-remitting MS according to disease severity.Conclusion. The data obtained in the Russian population suggest that mtDNA variations are involved in MS risk, to a greater extent in women.
