Abstract: Moreover, one HBV strain in the schizophrenia group presented I126S vaccine escape mutation (5.88%), while three HBV isolates showed Q129H, M133L, and G145R vaccine escape mutations in the control group (6.81%).
[Variability of Reverse Transcriptase Gene and S Gene in Lamivudine-treated Chronic Hepatitis B Patients].
Result: Amino acid substitutions in the major hydrophilic region predicted from twelve clones of HBV from the father's sample include T115I, T116A, S117G
Result: Five of the twelve substitutions, including T118K, T123N, T131N, M133L and N 145A, are associated with antibody escape.
Result: Two clones have T118K and N145A substitutions, two other clones have T131N and the final clone has M133L (Fig 2).
Discussion: The remaining two also have detection escape mutations (T131N and M133L).

Abstract: Single or multiple amino acids substitutions were found in 5 of 34 samples (14.7%) which includes I110T, P120T, P/T127I, A128P, M133L and G159V.
[Clinical significance of hepatitis B virus S gene mutation for recurrence of hepatitis B after liver transplantation].
Abstract: Furthermore, the frequently occurring mutations in the major hydrophilic loop of the S gene include the T125M, A128V and M133I/L.
Discussion: Several amino acid substitutions within the major hydrophilic loop were observed in our study population which included Y100D, Q101R/H, M103V/I, T125M, A128V, M133L, D144E and G145S.
Occult hepatitis B virus infection in anti-HBs-positive infants born to HBsAg-positive mothers in China.
Discussion: Other common escape mutations, including G145R, D144A, P142S, Q129H, I/T126N/A and M133L, were not found in our OBI isolates.

Abstract: HBsAg resulted undetectable by 3 of the 8 samples, derived from patients with multiple mutations: T126I-T131A-C139Y-E/D144G, T126I-M133L, and P120Q-T126I.

1Abstract: RESULTS: Ten HBsAg mutants having single mutation within the ""a"" determinant including P120E, T123N, Q129H, M133L, K141E, P142S, D144A, G145R, N146S and C147S together with a wt form were successfully constructed and expressed in CHO cells."
