Mutations in the HBV PreS/S gene related to hepatocellular carcinoma in Vietnamese chronic HBV-infected patients.

PMID: 35390033 2022 PloS one

Abstract: Most of S point-mutations were presented with low rates such as T47A/E/V/K (9.3%), P120S/T

Abstract: On multivariable analysis, males (OR = 4.51, 95%CI 1.78-11.4, p = 0.001), age>=40 (OR = 5.5, 95%CI 2.06-14.68, p = 0.001), W4P/R/Y on PreS1 (OR = 11.56, 95%CI 1.99-67.05, p = 0.006) and 4 S point-mutations as: T47A/E/V/K (OR = 3.67, 95%CI 1.19-11.29, p = 0.023), P120S/T (OR = 3.38, 95%CI 1.09-10.49, p = 0.035), S174N (OR = 29.73, 95%CI 2.12-417.07, p = 0.012), P203R (OR = 8.45, 95%CI 1.43-50.06, p = 0.019) were associated with HCC.

Abstract: Most OBI strains were wild-type HBV, but some substitutions V168A, S174 N, V177A, Q129R/L/H, G145A/R in S region of genotype B (OBIB) and T47K/V/A, P49H/L, Q101R/H/K, S174 N, L175S, V177A, T118 M/R/K, G145R/A/K/E, R160K/N in S region of genotype C (OBIC) strains were identified in high frequency.

Effects of amino acid substitutions in hepatitis B virus surface protein on virion secretion, antigenicity, HBsAg and viral DNA.

PMID: 27650283 2017 Journal of hepatology

Result: revealed previously identified immune escape mutations within the 'a' determinant region (sS117T, sK122R, sI126N/S/T, and sG145R), carboxyl terminal truncation mutations (sC69* and sW182*) and additional rarely described mutations (sE2G, sL21S, sR24K, sT47K/A

Molecular evolution of hepatitis B vaccine escape variants in China, during 2000-2016.

PMID: 28939157 2017 Vaccine

Abstract: Four sites (A5T/S, L21S, T/A126S and T/N131I/A) and 13 sites (N3S, T5A, G10Q/R/E, L21S, T47K/A/V, L98V/P, I/S126N/V/T, Q129H/R/L, T131P/I/N/A, G145A/R, L175S/F, L213I/S, V224A/G) were found to be under positive selection in genotype B and C HBV vaccine escape strains, re

Single-nucleotide substitution of Hepatitis B virus in intrauterine infection.

PMID: 25351410 2015 Journal of viral hepatitis

Abstract: Most of the mutations were synonymous in pre-S1/S2/S region, while mutations of C2990T, T3205A, A167G, C407A, A667T and A680C resulted in amino acid substitution of A90V, S162T, T47A, P127T, L213F and I218L, respectively.

Amino acid similarities and divergences in the small surface proteins of genotype C hepatitis B viruses between nucleos(t)ide analogue-naive and lamivudine-treated patients with chronic hepatitis B.

Abstract: With little influence on immune escape-associated mutation frequencies within 'a' determinant, LMV-monotherapy significantly induced classical LMVr-associated mirror changes sE164D/rtV173L, sI195M/rtM204V and sW196L/S/rtM204I, as well as non-classical ones sG44E/rtS53N, sT47K/A/rt

A multicentre molecular analysis of hepatitis B and blood-borne virus coinfections in Viet Nam.

PMID: 22720022 2012 PloS one

Result: Sixty-four specimens had mutations in the T cell epitope (including N40N/S, L42L/P, G44D/E/G, A45T, P46H, T47A/E/K/T).

Hepatitis B viral surface mutations in patients with adefovir resistant chronic hepatitis B with A181T/V polymerase mutations.

PMID: 20119580 2010 Journal of Korean medical science

Result: In Group C, there was one case of each of the following mutations: G10stop, L15V, I28V, W36L, F41S, T47A, Q51L, N59H, C69stop, L87V, F93L, V96G, L97P, G102C, T131P, Y200F, and C221Y.
