Chronic hepatitis B is a serious infectious liver disease that often progresses to liver cirrhosis and hepatocellular carcinoma; however, clinical outcomes after viral exposure vary enormously among individuals1. Through a two-stage genome-wide association study using 786 Japanese chronic hepatitis B cases and 2,201 controls, we identified a significant association of chronic hepatitis B with 11 SNPs in a region including HLA-DPA1 and HLA-DPB1. We validated these associations by genotyping two SNPs from the region in three additional Japanese and Thai cohorts consisting of 1,300 cases and 2,100 controls (combined P = 6.34 × 10-39 and 2.31 × 10 -38, OR = 0.57 and 0.56, respectively). Subsequent analyses revealed risk haplotypes (HLA-DPA1 0202-DPB1 0501 and HLA-DPA1 0202-DPB1 0301, OR = 1.45 and 2.31, respectively) and protective haplotypes (HLA-DPA1 0103-DPB1 0402 and HLA-DPA1 0103-DPB1 0401, OR = 0.52 and 0.57, respectively). Our findings show that genetic variants in the HLA-DP locus are strongly associated with risk of persistent infection with hepatitis B virus.
