Many GWASs conclude that the genetic variants in the HLA region (HLA-DP, HLA-DQ, HLA-DR and MICA), KIF1B, DEPDC5 and PNPLA3 influence HBV infection, its clinical course and the response to hepatitis B vaccination.
This study was conducted to determine whether polymorphisms near or in interferon-lambda (IFN-λs) genes and their receptor genes such as interleukin 28 receptor, alpha (IL28RA) and interleukin 10 receptor, beta (IL10RB) as well as p21-activated kinases 4 (PAK4) and iron/zinc purple acid phosphatase-like protein (PAPL), which are locate upstream of IFN-λs, and lastly the DEPDC5 gene are associated with hepatitis B virus-related liver disease in Han Chinese.
