N1 - Funding Information:
HLA allele and carrier frequencies were determined by direct counting. Haplotype frequencies were computed using PyPop software, distributed by the authors (version 0.6.0; http://www .pypop.org). Odds ratios were determined using logistic regression (JMP software, version 7.0.02; SAS Institute). Time-to-event analysis was determined using Kaplan-Meier life-table methods with significance assessed using the log-rank tests. The study was conducted jointly by the Mbeya Regional AIDS Control Programme (Tanzanian Ministry of Health), the Department of Infectious Diseases and Tropical Medicine, Ludwigs-Maximillians University (Munich, Germany), and the US Military HIV Research Program (MHRP, Rockville, Maryland). Review boards of participating institutions approved the study protocols, and informed consent was obtained from all study participants.

N2 - Here we explore associations between HLA variation and human immunodeficiency virus type 1 (HIV-1) acquisition and disease progression in a community cohort in Mbeya, Tanzania, a region that, despite harboring high rates of HIV-1 infection, remains understudied. African-specific allele HLA-A*74:01 was associated with decreased risk of infection (odds ratio [OR], 0.37; 95% confidence interval [CI], 0.14-0.80; P = .011) and with protection from CD4+ cell counts <200 cells/uL in women (OR, 0.31; 95% CI, 0.07-0.91; P = .032) and men (OR, 0.15; 95% CI, 0.01-0.78; P = .020). These associations remained significant after adjustment for linkage disequilibrium with HLA-B and HLA-C alleles. This observation calls for additional investigation of mechanisms by which HLA-A*74:01 may influence HIV-1 acquisition and control of the infection.
