Abstract: Known mutants Y100C, P127T and P120A associated to Y134H and S143T and new S mutants, which may potentially affect HBsAg expression and secretion and anti-HBs binding, were detected in baseline sera persisting up to the end of 9 years follow-up.
Mutation profiling of the hepatitis B virus strains circulating in North Indian population.
Abstract: Moreover, several mutations (sP105A, sI110S/L, sS136Y and sP127T/L) with significant differences in the frequency were identified in the S region of both cohorts.

Abstract: In the NUC therapy group the prevalence was 8.5% (12/142), with the following patterns: sY100C+sI110V, sL109I, sP120T, sP127T, sG130R+sG145X, sS132A+sY134N, sY134N+sG145R, s

Abstract: RESULTS: Of 47 serum samples from patients with chronic HBV infection, amino acid mutation in 'a' determinant occurred in 12 samples (25.53%,12/47), correlating with T126A, I126T/S, P127T, T131N, M133L, M133T and T140I; high proportion of mutation clustered in first loop of 'a' determinant (92.86%,13/14), rtV207I mutation in C domain of reverse transcription occured in one sample.
Analysis of hepatitis B surface antigen mutations in Mongolia: molecular epidemiology and implications for mass vaccination.
Abstract: Pro127Thr and Thr118Ala were the most common substitutions, which occurred in 6 (10.5%) and 3 (5.3%) subjects, respectively; none had Gly145Arg.
