Broad Range of Hepatitis B Virus (HBV) Patterns, Dual Circulation of Quasi-Subgenotype A3 and HBV/E and Heterogeneous HBV Mutations in HIV-Positive Patients in Gabon.
Abstract: A significant number of mutations (Thr118Val, Thr
Result: Several mutations were observed in 'a' determinant region of S gene such as, T118V, T125M, T126I, P127T, A128V and T/S143L/M according to different genotypes of HBV (Table 1).
Table: Thr126Ile
Discussion: Furthermore, Sequences of genotype C were found to have Thr126Ile and Thr131Ser mutations, and genotype A sequences have only Thr131Asn mutation in 'a' determinant region.
Virological Characteristics of Acute Hepatitis B in Eastern India: Critical Differences with Chronic Infection.
Abstract: Thirteen amino acid substitutions were identified: T126S, P127S, Q129R, T131N, M133T, and Y161S in the HBsAg-positive group; P120T, T126I, G145S, Y161F, E164V, and V168F in the occult-HBV group; and T143S in both groups.
[Clinical significance of hepatitis B virus S gene mutation for recurrence of hepatitis B after liver transplantation].
Abstract: Mutations in the S region (100%) were found especially in loop 1 of the major hydrophilic loop (MHL) at positions I110L, T114S, T126I and S113T, whereas mutations in the C region (65%) were within the basal core promoter region (position A1762T/G1764A) and precore region (position G1896A).
Molecular epidemiology and genotyping of hepatitis B virus of HBsAg-positive patients in Oman.
5Result: Within the ""a"" determinant, one (N131T) substitution was detected in all isolates and three additional variants (T126I, T143S, and G145A) were found in subject Y5 (Table 3)."
8Discussion: We did not find the most important and best-documented G145R mutation, but we found a G145A mutation and other substitutions (T126I, N131T, and T143S) within the ""a"" determinant."

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.
