Distribution of Pre-S1 and Pre-S2 mutation sites in the amino acid sequence of the B and C genotypes in the low- and high-level HBsAg groups. (A) Mutation sites in the amino acid sequences of the Pre-S1 and Pre-S2 proteins in the B genotype in the low-level HBsAg group. (B) Mutation sites in the amino acid sequences of the Pre-S1 and Pre-S2 proteins in the B genotype in the high-level HBsAg group. (C) Mutation sites in the amino acid sequences of the Pre-S1 and Pre-S2 proteins in the C genotype in the low-level HBsAg group. (D) Mutation sites in the amino acid sequences of the Pre-S1 and Pre-S2 proteins in the C genotype in the high-level HBsAg group. HBsAg, hepatitis B virus surface antigen.
