Abstract
Genotype G of hepatitis B virus (HBV) has only recently been discovered. This report describes the full-length sequence of genotype G HBV (designated 235/01) isolated in Germany from a chronic HBV carrier. The patient was hepatitis B e antigen-positive, had high HBV DNA levels of about 1010 copies/ml serum, lacked a measurable anti-HBc response, and was coinfected with human immunodeficiency virus type 1. Genome 235/01 showed characteristic genotype G-specific features: stop codons at codon 2 and 28 of the pre-C region and insertion of 36 nucleotides at the 5′ end of the C gene. It was nearly identical (≥99.7% identity) to both genotype G genomes (B1-89 and FR1 from France) described so far, suggesting either close epidemiological link among European genotype G isolates or high genetic stability of genotype G.
