We investigated the effect of RANTES polymorphisms on human immunodeficiency virus type 1 (HIV-1) disease progression in an urban population of Uganda. HIV-positive individuals homozygous for the INT1.1C polymorphism, which had been associated previously with low RANTES expression, were less likely to die than were those with other genotypes (hazard ratio, 0.53 [95% confidence interval, 0.33-0.83]; P=.007). This report of a non-human leukocyte antigen genetic association with HIV-1 and/or acquired immunodeficiency syndrome disease progression in an African population reveals a genetic effect different from that reported elsewhere for African Americans and may impact therapeutic strategies targeting the RANTES pathway in HIV infection.
