Association of Mal/TIRAP S180L variant polymorphism with decreased infection risk in patients with advanced HIV-1 infection
چکیده انگلیسی

ObjectivesMyD88 adaptor-like (Mal/TIRAP) is an adaptor protein bridging activation of Toll-like receptors 2 and 4 after stimulation by exogenous and endogenous ligands. We investigated the association between the presence of the S180L SNP of Mal and the risk of severe infection in individuals with human immunodeficiency virus (HIV)-1 infection.MethodsThe SNP S180L was determined in a cohort of 179 HIV-1 infected Greek patients. Analysis of the prevalence of this SNP in relation to the infectious complications was evaluated.ResultsOne hundred and thirty-two (73.3%) patients were bearing the wild type haplotype, 43 (24%) were heterozygous for the SNP, and four (2.2%) were homozygous for the variant allele. The individuals with a nadir CD4 count <200 cells/mm3 who carried the 180L variant demonstrated a 4-fold decrease in the odds ratio (OR) for any serious infection compared with those who carried the wild-type 180S genotype (OR 0.58 vs OR 2.6, p = 0.016).ConclusionsThis study suggest a protection effect of the Mal S180L SNP against serious infections in HIV-1 infected individuals with low CD4 cell counts.

► Genotyping for TIRAP/Mal was performed in a Greek cohort of HIV-1 infected individuals. ► Association of S180L SNP of Mal and risk of infection was assessed. ► Individuals with a nadir CD4 count <200 cells/mm3 were studied separately. ► The S180L variant was associated with a 4-fold decrease in the odds ratio for infection. ► This study suggests a protection effect of the Mal S180L SNP against serious infections.
