Effect of CCR5-32 heterozygosity on HIV-1 susceptibility: A meta-analysis

So far, many studies have investigated the distribution of CCR5 genotype between HIV-1 infected patients and uninfected people. However, no definite results have been put forward about whether heterozygosity for a 32-basepair deletion in CCR5 gene (CCR5-32) can affect HIV-1 susceptibility. We performed a meta-analysis of 18 studies including more than 12000 subjects for whom the CCR5-32 polymorphism was genotyped. Odds ratio (OR) with 95% confidence interval (CI) were employed to assess the association of CCR5-32 polymorphism with HIV-1 susceptibility. Compared with the wild-type CCR5 homozygotes, the pooled OR for CCR5-32 heterozygotes was 1.02 (95%CI, 0.88–1.19) for healthy controls (HC) and 0.95 (95%CI, 0.71–1.26) for exposed uninfected (EU) controls. Similar results were found in stratified analysis by ethnicity, sample size and method of CCR5-32 genotyping. The meta-analysis indicated that HIV-1 susceptibility is not significantly affected by heterozygosity for CCR5-32.
