In a North American, treated, adherent human immunodeficiency virus (HIV)-positive cohort (self-identified whites, n = 175; blacks, n = 218), we investigated whether CYP2B6 (516G>T, 983T>C), UGT2B7 (IVS1+985A>G, 802C>T), MDR1 3435C>T, chemokine (C-C motif) receptor 2 (CCR2) 190G>A, and CCR5 (-2459G>A, Δ32) polymorphisms influenced the time to achieve virologic success (TVLS).
A single nucleotide polymorphism (SNP) at codon 64 in the CC chemokine receptor 2 gene (CCR2 V64I) has been associated with a dominant effect of delaying disease progression from human immunodeficiency virus-1 (HIV-1) infection to acquired immunodeficiency syndrome (AIDS).
Of the 99 HIV-seronegative female workers, 19 (19.2%) were heterozygous for the CCR2b-V64I mutation compared with 37 (23%) of the 161 HIV-seropositive FSW (P = 0.47).
