Result: The sA159V-positive patients had higher rates of coexisting drug-resistance mutations than the sA159V-negative patients.
Result: Three
Result: Three sA159V-containing resistant mutants had significantly higher replication capacities than their sA159V-lacking counterparts (M2 vs M3, M4 vs M5, M6 vs M7, all P < 0.05) (Figure 4).
Discussion: In addition, the sA159V mutation alone was detected before the emergence of the resistance mutation and was recovered after the sA159V-containing resistant mutants were effectively suppressed by rescue therapy.

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.
