Abstract |
Host genetic, environmental and viral factors are classified as three categories that determine clinical outcomes of hepatitis B virus (HBV) infection. The objective of this study was to detect the associations between polymorphisms rs346473 and rs346482 in Rho GTPase-activating protein 24 (ARHGAP24) gene and disease progression of HBV infection in Han Chinese population. These two SNPs were found by our DNA pooling using Affymetrix Genome-Wide Human Mapping SNP6.0 Array in HBV carriers, and verified by using TaqMan 7900HT Sequence Detection System with 758 progressed HBV carriers versus 300 asymptomatic HBV carriers (AsC) in a discovery phase and 971 progressed HBV carriers versus 328 AsC in a replication phase. Multivariable logistic regression revealed that individuals with genotype TT at variant rs346473 displayed remarkable correlations with disease progression of HBV infection both in the discovery phase (OR, 2.693; 95% CI, 1.928-3.760; P=6.2×10(-9); additive model) and the replication phase (OR, 1.490; 95% CI, 1.104-2.012; P=9.0×10(-3); additive model). These two SNPs were in strong linkage disequilibrium with D'=0.99 and r (2)=0.951, and haplotype TT disclosed an increased susceptibility to HBV progression (OR, 1.980; 95% CI, 1.538-2.545; P=8.1×10(-8)). These findings suggest that polymorphism rs346473 in the ARHGAP24 gene might be a part of the genetic variants underlying the susceptibility of HBV carriers to disease progression.
