Analysis of the complete genome of hepatitis B virus subgenotype C2 isolate NHB17965 from a patient with uncomplicated chronicity

The number of chronic cases of hepatitis B virus (HBV) is increasing rapidly in the world. Herein, we report a complete genome of HBV subgenotype C2 (HBV/C2) with current common amino acid substitutions from a patient with chronic HBV without liver complications. Complete genome analysis revealed that the isolated strain was a non-recombinant wild type and had several regular substitutions in the reverse transcriptase domain and small surface proteins of HBV. The isolated complete sequence could be considered as a chronic reference strain of HBV/C2 in Bangladesh. This study may help clinicians and scientists gain in-depth knowledge on common substitutions of HBV/C2 genome and to identify potential therapies against chronic HBV infections.
