Wild-type levels of pregenomic RNA and replication but reduced pre-C RNA and e-antigen synthesis of hepatitis B virus with C(1653) --> T, A(1762) --> T and G(1764) --> A mutations in the core promoter.

Abstract excerpt

Hepatitis B virus (HBV) isolates with A-1762 to T and G-1764 to A mutations in the core promoter have been associated with active hepatitis, severe liver disease following liver transplantation, hepatocellular carcinoma and acute fulminant courses--in the latter case combined with a C-1653 to T mutation. In this study, a mutant core promoter region containing the T-1653, T-1762 and A-1764 mutations was placed...
