Abstract: HBsAg production was significantly lower and the replication capacity was significantly higher, without a significant difference in LAM/ETV susceptibility, in sA159V-containing LAM/ETV-resistant mutants than in their sA159V-lacking counterparts.
Abstract: Among these, sA159V was detected in 1.95% (136/6982) of patients with resistance mutations and 1.08% (134/12,458) of patients lacking resistance mutations (P < 0.05).
Abstract: Phenotypic analyses were performed to evaluate HBsAg production, replication capacity, and drug-induced viral inhibition of patient-derived drug-resistant mutants with or without the coexistence of sA159V

1Abstract: Decreased binding to ""a"" determinant-specific monoclonal antibody was observed for variants Pro120 to Ser120, Ala159 to Val159, and Phe183 to Cys183."
Abstract: These include Asn116 to Thr116, Val118 to Ala118, Pro120 to Ser120, Ala159 to Val159, Phe183 to Cys183, and Val184 to Ala184.
