Occult hepatitis B virus (HBV) infection (OBI) is primarily characterized by the persistence of HBV‐DNA in the liver tissues and/or in the serum without detectable HBsAg. Human leukocyte antigen (HLA) polymorphisms have been found to be strongly associated with HBV in different ethnic backgrounds. The association of HLA‐DRB1‐DQB1 haplotypes with OBI has not been previously reported in China. The aim of this study was to identify the potential association of HLA‐DRB1‐DQB1 haplotypes that may be involved in OBI genetic susceptibility.
