Discussion: This result is consistent with a previous study demonstrating that the HBx with A1762T/G1764A (K130M/V131I) mutation (the same as M1-HBx in our study) had a stronger tumorigenic effect than its WT counterpart in a SB mouse model.
Differences in HBV Replication, APOBEC3 Family Expression, and Inflammatory Cytokine Levels Between Wild-Type HBV and Pre-core (G1896A) or Basal Core Promoter (A1762T/G1764A) Mutants.
Discussion: The A1762T/G1764A mutations are responsible for the K130M/V131I mutations found in the HBx.

Abstract: The frequency of aminoacid substitution in proapoptotic domain was higher in HBeAg negative participants including I127V (34%), K130M (34%), V131I (40%).
Abstract: The frequency of double mutation (K130M+V131I) and triple mutation (I127V+K130M+V131I) were found to be higher (32% and 36%) in HBeAg negative participants.

Abstract: In addition, the double mutation K130M/V131I and the triple mutation N88V/K130M/V131I were associated with a 2.5 times higher risk of advanced liver disease.
HBx-K130M/V131I Promotes Liver Cancer in Transgenic Mice via AKT/FOXO1 Signaling Pathway and Arachidonic Acid Metabolism.
Abstract: IMPLICATIONS: Our findings suggested that HBx-K130M/V131I-mutant variant promoted HCC progression by activating AKT/FOXO1 pathway and inducing stronger inflammation in liver via AA metabolism.
Abstract: Taken together, the increased rate of HCC observed in chronic hepatitis B patients with K130M/V131I-mutated X protein, may be due to changes in AA metabolism and AKT/FOXO1 signaling.
Abstract: To compare the potential tumorigenic effects of K130M/V131I (Mut) and wild-type (WT) HBx on PMID: 31565220

Abstract: Multinomial regression analysis revealed that the K130M/V131I mutations were correlated with CLD progression (OR, 7.629; 95% CI, 1.578-36.884).
Abstract: Significant differences in viral load were found in HBV-infected patients who had X gene mutations, such as R87W/G, I127L/T/N/S and K130M/V131I mutations (P<0.05).
Abstract: The presence of K130M and V131I mutations may be predictive for the progression of HBV-associated CLD in Indonesia.
Result: Multinomial regression analysis confirmed that K130M/V131I mutati

Introduction: Mutations within the X gene, including V5M, I127T, K130M, and V131I/L, are risk factors for HCC and may promote the progression of liver degradation (Kim et al.,).
Hepatitis B virus (HBV) X gene mutations and their association with liver disease progression in HBV-infected patients.
Abstract: H94Y and K130M mutations were also significantly associated with severe liver disease.
Abstract: One double mutation (K130M+V131I) and two triple mutations (I127T+K130M+V131L and K130M+V131I+F132Y) were observed, with significant rising prevalence through progressive clinical phases of liver disease to HCC.

HBx-K130M/V131I Promotes Liver Cancer in Transgenic Mice via AKT/FOXO1 Signaling Pathway and Arachidonic Acid Metabolism.
Abstract: Hepatitis B virus (HBV) genomic mutations A1762T, G1764A and AG1762/1764TA cause production of HBV X protein (HBx) mutants, namely K130M, V131I and KV130/131MI.
HBx mutations promote hepatoma cell migration through the Wnt/beta-catenin signaling pathway.
Introduction: A1762T/G1764A (TA) mutations in the core promoter, which overlap with the HBx gene, are found commonly in HCC and are independent risk factors for the progression of HCC during Introduction: 127 (isoleucine to asparagine/serine/threonine), 130 (lysine to methionine), 131 (valine to isoleucine), and 132 (phenylalanine to tyrosine), which might affect the biological activity of HBx.18, 19 However, the potential role of HBx Combo mutations in hepatocarcinogenesis is largely unknown.
