  1. Abstract:

    Chronic hepatitis B virus (HBV) infection is a major health issue, especially in Asia. A recent genome-wide association study (GWAS) implicated genetic variants in the human leukocyte antigen (HLA)-DP locus associated with chronic hepatitis B in Japanese and Thai populations. To confirm whether the polymorphisms at the HLA-DP genes are associated with persistent chronic HBV infection in Han Chinese, we conducted an independent casecontrol study using 521 persistent chronic HBV carriers and 819 controls that included 571 persons with HBV natural clearance and 248 never HBV-infected (healthy) individuals. Eleven single nucleotide polymorphisms (SNPs) in a region including HLA-DPA and HLA-DPB and an adjacent SNP in strong linkage disequilibrium (LD) with a neighboring HLA-DR13 locus were genotyped using the TaqMan SNP genotyping assay. Eleven variants at HLA-DP showed a strong association with persistent chronic HBV carrier status (P = 1.82 X 10(-12) to 0.01). We also stratified the analysis by HBV clearance status to test the association between these polymorphisms and HBV natural clearance; similar results were obtained (P = 2.70 x 10(-1)1 to 0.003). Included SNPs define highly structured haplotypes that were also strongly associated with HBV chronic infection (block 1: odds ratio [OR] = 0.54, P = 8.73 x 10(-7); block 2: OR = 1.98, P = 1.37 x 10(-10)). These results further confirm that genetic variants in the HLA-DP locus are strongly associated with persistent HBV infection in the Han Chinese population. (HEPATOLOGY 2011;53:422-428)
