Abstract: Furthermore, the mutations sY100C, sQ101R/K, sS114A, sP120T, sT/I126A/N/S, sQ129R, sM133L/T/S and sG145R/A were prevalent in at least one genotype, with a frequency higher than 1%, which indicated that these mutations were relatively common.
HBV genotypes and drug resistance mutations in antiretroviral treatment-naive and treatment-experienced HBV-HIV-coinfected patients.
Method: The sequences were examined for known vaccine escape mutations (sG145R/A, sP142S, sI/T126A/N/I/S, sQ129H/R, sM133L, sD144A/E, sP120S/E, sK141E, sP134I, and sT116N), immunoprophylaxis escape mutations (
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.
[The panels of serums, containing various subtypes and mutant forms of HBsAg, to evaluate the diagnostics sensitivity of kits oa reagents detecting HBsAg].
Abstract: The testing of reagents kits to detect HBsAg using twi panels containing recombinant and native variants of HBsAg, demonstrated that these kits enable to detect various sero-vatriants of HBsAg (ayw2, adw2, ayw3varA, ayw3varB, adrq-) in concentration 0.1-0.01 IU/l and the so called elusive mutant forms of HBsAg of recombinant and native origin (G145R, Q129R, Q129H, Q129L, T143K, T126N, T126S, D144A, M133L, K141E and P142S).

Method: Mutations at 10 S envelope protein positions were considered possible vaccine-escape mutations, including sP120T, sI/T126N/A, sQ129H, sM133L, sK141E, sP142S, sD144A, sG145R, sF158Y, and s PMID: 19212700

Abstract: Interestingly, Thr123Ala and Gly145Arg were observed only in failure-group mothers, whereas Thr126Asn, Thr126Ser, Thr143Asn, Asp144Gly, and Asp144Ala were seen in the success group.
Molecular epidemiological study of hepatitis B virus in Thailand based on the analysis of pre-S and S genes.
1Abstract: Regarding the ""a"" determinant, 2/43 (4.65%) and 2/104 (1.92%) samples of vaccinated and non-vaccinated subjects, respectively, displayed mutations, all ofwhich were Thr126Asn."

Abstract: Four out of these six cases had a point mutation within the 'a' determinant; they were Gly-145-Ala, and Ile/Thr-126-Asn/Ser.
Prevalence of naturally occurring surface gene variants of hepatitis B virus in nonimmunized surface antigen-negative Chinese carriers.
1Abstract: These changes involved 11 positions inside and 5 outside of the historical first and second loops of the ""a"" determinant, and included the following: Q101K, T115A, K122N, T123A, T126N, Q129N, G130R, T131I, M133T, F134L, C138Y, K141E, P142S, G145R, N146S, and C147F/R."
