ABSTRACT
The genetic variations in APOBEC3G gene are correlated with HIV disease progression. These variations differ in different ethnic groups. The prevalence of APOBEC3G (-90C/G, -571G/C) variations have not been studied in Indian population. Hence, we assessed the occurrence of APOBEC3G polymorphisms in HIV patients and its association with acquisition of HIV and disease progression. Polymorphisms in APOBEC3G were genotyped in a total of 153 HIV patients, naïve to ARV and 156 healthy controls by PCR-RFLP method. In single locus model, the frequency of distribution of APOBEC3G -90CG, -571 GC genotypes were higher in HIV patients as compared to healthy controls (57.5% vs. 50.0%, OR = 1.22; 17.0% vs. 12.8%, OR = 1.39). In double locus model, the dominant -571 GC + CC genotype was distributed at a much higher frequency in HIV patients as compared to healthy controls (18.3% vs. 14.1%, OR = 1.50). The frequency of APOBEC3G -571CC and CC + GC genotypes were higher in early HIV disease stage as compared to healthy controls (23.9% vs. 12.8%, OR = 2.23, P = 0.08; 28.3% vs. 14.1%, OR = 2.40, P = 0.04). APOBEC3G-571 GC and GC + CC genotypes were more prevalent in HIV patients consuming tobacco and alcohol as compared to non-users (22.7% vs. 15.3%, OR = 1.71, P = 0.56; 27.3% vs. 16.5%, OR = 1.90, P = 0.39 and 31.6% vs. 13.6%, OR = 2.31, P = 0.08; 36.8% vs14.8%, OR = 2.49, P = 0.04, respectively). In conclusion, APOBEC3G-571G/C polymorphism was associated with the early stage of HIV infection and could potentially influence HIV disease progression in alcohol users. The distribution of APOBEC3G polymorphisms and its haplotypes were not significantly different between HIV patients and healthy controls.
