TRIM5alpha H43Y polymorphism and susceptibility to HIV-1 infection: A meta-analysis

Abstract

TRIM5alpha is an antiviral factor that can greatly limit HIV-1 infection. Although several researchers have investigated whether TRIM5alpha H43Y polymorphism influences the risk of HIV-1 infection, no definite conclusion has ever been drawn. In this research, we performed a meta-analysis to generate a more robust estimate of the association between TRIM5alpha H43Y and susceptibility to HIV-1 infection. In total, six studies including 1,713 HIV-1 patients and 1,814 controls were included. TRIM5alpha H43Y polymorphisms of all individuals were genotyped. Odds ratios (ORs) with 95% confidence intervals were presented as the result of analysis. ORs for the main analysis were 0.82 (95% CI: 0.63-1.08) in the allelic comparison, 0.57 (95% CI: 0.34-0.95) in the homozygote comparison, 0.82 (95% CI: 0.57-1.16) in the dominant model, and 0.56 (95% CI: 0.33-0.93) in the recessive model. In the subgroup analysis by ethnicity, significantly decreased risks of infection were detected in the Asian population (homozygote comparison: 0.50, 95% CI: 0.28-0.89; recessive model: 0.49, 95% CI: 0.28-0.87), whereas such effects were not observed in the non-Asian population. Our meta-analysis indicates that TRIM5alpha H43Y polymorphism is associated with a decreased risk of HIV-1 infection in the homozygote comparison and recessive model. This polymorphism may act as a protective factor against HIV-1 infection, especially in Asians.
