Abstract

Although there have been many studies of gene variant association with different stages of HIV/AIDS progression in United States and European cohorts, few gene-association studies have assessed genic determinants in sub-Saharan African populations, which have the highest density of HIV infections worldwide. We carried out genome-wide association studies on 766 study participants at risk for HIV-1 subtype C (HIV-1C) infection in Botswana. Three gene associations (AP3B1, PTPRA, and NEO1) were shown to have significant association with HIV-1C acquisition. Each gene association was replicated within Botswana or in the United States–African American or United States–European American AIDS cohorts or in both. Each associated gene has a prior reported influence on HIV/AIDS pathogenesis. Thirteen previously discovered AIDS restriction genes were further replicated in the Botswana cohorts, extending our confidence in these prior AIDS restriction gene reports. This work presents an early step toward the identification of genetic variants associated with and affecting HIV acquisition or AIDS progression in the understudied HIV-1C afflicted Botswana population.

Significance

The search for genetic variants associated with resistance or susceptibility to HIV/AIDS already yielded insights that allowed developing therapeutics that contribute to dramatic reduction in AIDS-related comorbidities. Unfortunately, nearly all studies focused on European-descent populations, even though most infections happen in Africa. In this genome-wide association study we explored the genetic background of several hundred individuals from Botswana in search of associations with HIV infection. We discovered several genetic variant associations in genes implicated in HIV/AIDS pathogenesis. We also confirmed several associations reported in previous research. This study provides valuable data on the influence of human genetic variation on HIV-1C infection and pathogenesis in southern Africa, a region with the world’s largest number of HIV-1 infections.
