Polymorphism of UGT1A1*28 (TA)7 and liver damage in hepatitis B virus-positive patients in Albania
Hepatitis B virus (HBV) is the infectious agent of both acute and chronic hepatitis. HBV exists in multiple genotypic variants that differ in their capacity to become persistent chronic infections and in their clinical manifestations, including hepatocellular carcinoma. The 8 genotypes (A-H) of HBV show a specific worldwide geographic distribution and are correlated with different disease course, severity, and response to therapy.
