8Discussion: According to the reports, the ""a"" determinant of OBI patients contains Gly145Arg/Ala/Ile/Trp/Glu (G145R/A/I/W/E), Leu109Arg (L109R), Gly119Arg (G119R), Pro120Thr (P120T), Lys122Ile (K122I), Thr126Asn (T126N), Thr127Arg (T127R), Gln129Asn (Q129N), Thr131Asn (T131N
Amino acid substitutions at positions 122 and 145 of hepatitis B virus surface antigen (HBsAg) determine the antigenicity and immunogenicity of HBsAg and influence in vivo HBsAg clearance.
Abstract: Genetic immunization in mice demonstrated that the priming of anti-HBs antibody response was strongly impaired by the substitutions K122I, G145R, and others, like G145I, G145W, and G145E.
