title: [Frequencies of the CCR2-64I and SDF1-3'A alleles associated with progression of the HIV-1 disease in healthy individuals from Moscow].
abstract: The frequencies of two mutations associated with the development of clinical symptoms upon infection with human immunodeficiency virus type 1 (HIV-1) were determined in a cohort of individuals from Moscow. Allelic frequency of the first mutation, CCR2-64I, causing the substitution of valine with isoleucine in the CCR2 chemokine receptor, was 0.1106 (95% confidence interval, 0.0714-0.1498). The frequency of the second mutation the G to A substitution in the 3'-untranslated region of the stromal-derived factor 1 encoding gene, SDF1-3'A, was 0.2125 (95% confidential interval, 0.1608-0.2642). Both values were slightly higher than those obtained earlier for Western European countries. This result can be explained by higher proportion of Asian immigrants, characterized by higher frequencies of these mutations, in the population of Moscow.
