PreS1 Mutations Alter the Large HBsAg Antigenicity of a Hepatitis B Virus Strain Isolated in Bangladesh.

PMID: 31952213 2020 International journal of molecular sciences

Abstract: Clinically significant mutations, such as preS1 C2964A, reverse transcriptase domain I91L, and small HBsAg N3S, were identified.

Result: However, some mutations (H9Y, N13H, I91L, I269L, and V278I) were found in the RT domain that are not associated with drug resistance, according to Geno2pheno:hbv.

Result: Only one putative NA-resistant mutation, I91L, was found, and no primary, secondary, pre-treatment, or drug-resistant mutations were observed in the RT domain of

Method: A total of 26 types of RT mutations, including rtS53N, rtT54N, rtL82M, rtV84M, rtS85A, rtI91L, rtY126C, rtT128I/N, rtN139D, rtW153Q, rtF166L, rt

Abstract: T54N, L80I/V, I91L/V, L180M, M204I/V, Q215P/S, and F221Y/S showed the highest number of mutations in all groups with different frequencies.

Characterization of antiviral resistance mutations among the Eastern Indian Hepatitis B virus infected population.

Introduction: Recently, HBVrt domain mutations which have been reported in the literature as supposed drug resistant mutations but are not verified experimentally were classified as putative NA resistant (NAr) mutations (such as S53N, T54N, L82M, V84M, S85A, I91L, Y126C, T128I, T128N, N139D, W153Q, F166L).

Result: All the isolates having rtI91L were associated with rtV103I.

Result: Analysis of pol

Abstract: Considerable prevalence of differential BCP (1752C, 1753C, 1762T/1764A, 1753C+1762T/1764A, 1773C, and 1814C) and reverse transcriptase (rt) gene (rtI91L, rtL93P, rtS106C, rtR110G, rtN118T, rtS119T, rtY126H, rtG127W/R, rtC136R, and
