Recombinant HBsAg of the Wild-Type and the G145R Escape Mutant, included in the New Multivalent Vaccine against Hepatitis B Virus, Dramatically Differ in their Effects on Leukocytes from Healthy Donors In Vitro.
Introduction: Across different genotypes, the most frequent substitutions were I/T126S (1.8%), G145R (1.2%), M133T (1.2%), Q129R (1.0%), I/T126A (0.8%), and P120T (0.8%).
Introduction: These major mutations were more common in genotypes A (P120T, 3.2%), B (I/T126A, 2.8%; Q129R, 2.2%), C (I/T 126S, 3.9%; M133T, 1.9%), and G (G145R, 5.0%).
Prevalence, genotype distribution and mutations of hepatitis B virus and the associated risk factors among pregnant women residing in the northern shores of Persian Gulf, Iran.
Discussion: P120T and G145R mutations in the S gene are associated with low responses to HBV vaccination and immunoglobulin therapy as well as failures of diagnostic tests.
Discussion: Nevertheless, P120T and G145R mutations associated with failure of HBsAg detection were not found in this sample.
Mutations in the HBV PreS/S gene related to hepatocellular carcinoma in Vietnamese chronic HBV-infected patients.
Abstract: The observed mutations were T115S (3/20, 15%), P120T/S (3/20, 15%), T126S (1/20, 5%), Q129R (2/20, 10%), M133T (2/20, 10%), S143L (5/20, 25%), D144E/A (3/20, 15%), and G145R/A (4/20, 20%).
Result: The following mutation pairs were observed: T115S (3/20, 15%), P120T/S (3/20, 15%), T126S (1/20, 5%), Q129R (2/20, 10%), M133T (2/20, 10%), S143L (5/20, 25%), D144E/A (3/20, 15%), and G145R/A
In silico functional and structural characterization of hepatitis B virus PreS/S-gene in Iranian patients infected with chronic hepatitis B virus genotype D.
Introduction: Also, mutations may occur in association with either vaccine-induced immune-escape (P120T, K122R, T126S, Q129H, G130N, M133L, and M133T) or in relation to the patients with occult HBV infection (Y100C, C124R, C124Y, K141E, and D144A).

Abstract: In particular, these mutations were sQ101H/K/R, sS114A/L/T, sT118A/K/M/R/S/V, sP120A/L/Q/S/T, sT/I126A/N/P/S, sM133I/L/T, sC137W/Y, sG145A/R, and sA159G/V.
Result: In particular, mutations were detected in 67/63
Comprehensive Analysis of Clinically Significant Hepatitis B Virus Mutations in Relation to Genotype, Subgenotype and Geographic Region.
Result: The most common substitutions were I/T126S (1.8%), G145R (1.2%), M133T (1.2%), Q129R (1.0%), I/T126A (0.8%), and P120T (0.8%).
Result: These major mutations were more frequent in genotypes A (P120T, 3.2%), B (I/T126A, 2.8%; Q129R, 2.2%), C (I/T126S, 3.9%; M133T, 1.9%), and G (G145R, 5.0%).
