CXCR6 genetic variation was described for HIV-1-uninfected black (n=41) and Caucasian (n=40) South Africans. We also investigated the CXCR6 rs2234358 and rs2234355 single nucleotide polymorphisms in HIV-1 disease control in 124 HIV-1-infected drug-naïve black individuals [elite controllers (n=11), viraemic controllers (VCs, n=30), high viral load long-term nonprogressors (HVL LTNPs, n=11) and progressors (n=72)] compared to healthy controls (HCs; n=232). The rs2234358-T allele was underrepresented in VCs (40.0%) compared to HCs (59%, P=0.006), HVL LTNPs (72.7%, P=0.012) and progressors (59%, P=0.014). The rs2234358-TT genotype was underrepresented in VCs (7%) compared to progressors (32%; OR=6.57, P=0.006) and HCs (35%; OR=7.18, P=0.001, Pbonferroni=0.034). The rs2234355-GA genotype was overrepresented in VCs (80%) compared to HCs (50.4%; OR=0.25, P=0.003) and progressors (29.17%; OR=0.10, P=3.8×10−5, Pbonferroni=0.001). The combination of rs2234355-GA in the absence of rs2234358-TT was overrepresented in VCs (80%) compared to HCs (32.6%, OR=0.12, P=1×10−6, Pbonferroni=3.4×10−5) and to progressors (16.7%; OR=0.05, P<1×10−8, Pbonferroni<1×10−7).
