Sequence analysis of amino acid differences in the HCV E2 glycoproteins of H77c and variants outside HVR1^a

^aType 1 (yellow), 2002 residues that are identical, with H91, H92, and H95 variants, but with an exception in one 1991 variant (A/T) at position 713; type 2 (purple), mutations in specific variants but not in the 2002 variant or mutations in both 2002 and other variants; type 3 (green), 2002-specific mutations, but with H77c being different from H91, H92, and H95 variants at residues 444 and 446; type 4 (red), 2002-specific mutations.
