Abstract

Objective: This study aimed to investigate the role of Human Leukocyte Antigen (HLA)-G in the susceptibility to HIV-1 infection through the analysis of the HLA-G 3' untranslated region (UTR) polymorphisms 14. bp insertion/deletion (rs66554220) and +3142C>G (rs1063320). Design: We analyzed 582 HIV-1 infected patients and 626 uninfected individuals from Brazil and Italy in a case-control study. Methods: HLA-G polymorphisms were genotyped using PCR, PCR-RFLP assays or direct sequencing. All analyses were stratified by ethnicity. Genotypic, allelic and diplotypic frequencies were compared between HIV-1 infected subjects and controls using Chi-square or Fischer exact tests. Also, haplotypic frequencies were estimated using MLocus software. Results: African-derived HIV-infected individuals presented a higher frequency of the 14bp insertion allele as compared to non-infected individuals (0.468 versus 0.373, respectively; pBonf=0.010). A higher frequency of the 14bp insertion +3142G (insG) haplotype (0.456 versus 0.346, p
