  • Title: A common HLA-DPA1 variant is a major determinant of hepatitis B virus clearance in Han Chinese.
    Author: An P, Winkler C, Guan L, O'Brien SJ, Zeng Z, HBV Study Consortium.
    Journal: J Infect Dis; 2011 Apr 01; 203(7):943-7. PubMed ID: 21402545.
    Abstract:
    A recent genome-wide study showed that the single nucleotide polymorphisms (SNPs) in the HLA-DP region were associated with chronic hepatitis B virus (HBV) infection in Japanese and Thai persons. We tested the effects of HLA-DP SNPs for all major HBV outcomes in Han Chinese (n = 1742): HBV resistance, clearance, chronic infection, cirrhosis, and hepatocellular carcinoma. HLA - DPA1 rs3077 T was strongly associated with decreased risk of chronic HBV infection (odds ratio, .62; P = .001), consistent with the previous report. We showed for the first time to our knowledge that it is a predictor for HBV clearance (odds ratio, 2.41; P < .001). However, rs3077 was not associated with the development of cirrhosis or hepatocellular carcinoma.
