[Comparative analysis of distribution of mutant alleles of the gene coding for the CCR-5 chemokine receptor, among people in Russia, infected and not infected with HIV-1].

Comparative analysis of the distribution of deletion mutations of CC-chemokine receptor 5 (CCR-5) gene among HIV-1 infected and not infected subjects in Russia showed the incidence of the heterozygous genotype to be 17.8% among both HIV-infected and seronegative subjects. The incidence of the homozygous genotype for the deletion among seronegative individuals was 0.6%, but no homozygotes were found among HIV-1 infected patients. Study of the incidence of the mutant CCR-5 allele among patients infected with different HIV-1 subtypes showed that the susceptibility of heterozygotes to HIV-1 infection was not associated with any special genetic subtype.
