Sequence analysis of the hepatitis D virus across genotypes reveals highly conserved regions amidst evidence of recombination.

ABSTRACT: Sequence diversity of the hepatitis D virus (HDV) may impact viral clearance, contributing to the development of chronic infection. T-Cell-induced selection pressure and viral recombination can induce diversity throughout the viral genome including coding and noncoding regions, with the former potentially impacting viral pathogenicity and the latter exerting regulatory functions. Here, we aim to assess sequence variations of the HDV genome within and across HDV genotypes. Sequences from 721 complete HDV genomes and 793 large hepatitis D antigen (L-HDAg) regions belonging to all eight genotypes and published through December 2023 were compiled. Most retrieved sequences belonged to Genotype 1, whereas for Genotype 8, the fewest sequences were available. Alignments were conducted using Clusta
