Variants in the CYP7B1 gene region do not affect natural resistance to HIV-1 infection.

ABSTRACT:

Background

The genetic bases of natural resistance to HIV-1 infection remain largely unknown. Recently, two genome-wide association studies suggested a role for variants within or in the vicinity of the CYP7B1 gene in modulating HIV susceptibility. CYP7B1 is an appealing candidate for this due to its contribution to antiviral immune responses. We analyzed the frequency of two previously described CYP7B1 variants (rs6996198 and rs10808739) in three independent cohorts of HIV-1 infected subjects and HIV-1 exposed seronegative individuals (HESN).

Findings

rs6996198 and rs10808739 were genotyped in three case/control cohorts of sexually-exposed HESN and HIV-1-infected individuals from Italy, Peru and Colombia. Comparison of the allele and genotype frequencies of the two SNPs und
