A haplotype in the CCR5 gene promoter was associated with the susceptibility to HIV-1 infection in a northern Chinese population.
It has been reported that single nucleotide polymorphisms (SNPs) in the promoter of the CCR5 gene are associated with the risk for HIV-1 infection and AIDS progression. Using resequencing, we performed a systematic survey of 78 HIV-1 seropositive individuals and 70 population-matched healthy control individuals from northern China to investigate SNPs of the CCR5 gene promoter and evaluated their effects on HIV-1 infection and the progression of AIDS. Linkage disequilibrium (LD) plots and haplotypes were generated using Haploview software. The association analyses were statistically compared using the Chi-square test with SPSS13.0 software for Windows. Seven SNPs (58755A>G, 58791C>T, 58934G>T, 59029A>G, 59353C>T, 59402A>G and 59653C>T) in the region of the CCR5 gene promoter were evaluated in this study. Among the seven SNPs, the minor allele frequencies of 58755G and 58791T were less than 2%. The differences in frequencies of the other five SNPs were not significant between case and control cohorts (P>0.05). In the case cohort, the association between these SNPs and clinical features (CD4+ T-lymphocyte counts and clinical categories) was not significant (P>0.05); however, there was a significant association between the haplotype GGTAC and susceptibility to HIV-1 infection (P<0.05), which is not consistent with other reports studied in different populations. The results suggest that the haplotype GGTAC may have a role in the process of HIV-1 infection in the northern Chinese population.
