Genetic variation of occult hepatitis B virus infection.

World journal of gastroenterology - 7 Apr 2016

Zhu Hui-Lan, Li Xu, Li Jun, Zhang Zhen-Hua

Abstract excerpt

Occult hepatitis B virus infection (OBI), characterized as the persistence of hepatitis B virus (HBV) surface antigen (HBsAg) seronegativity and low viral load in blood or liver, is a special form of HBV infection. OBI may be related mainly to mutations in the HBV genome, although the underlying mechanism of it remains to be clarified. Mutations especially within the immunodominant "α" determinant of S protein...
