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.
Result: T1753A, A1761C, and G1764A mutations caused the conversion of Ile Asn at amino acid 127 (I127N), Lys Gln at amino acid 130 (K130Q), and Val Leu at amino acid 131 (V131L) of the X protein, respectively (S3 Fig).
Result: Of these, T1753A and A1761C mutations were detected in one sample (HB55); and G1764T/A, C1766G/T, and C1773T mutations were detected in two samples (HB35 and HB55).

Abstract: Cox regression analysis showed that independent predictors for mortality at week 24 of treatment in SAE patients were higher international normalized ratio, the presence of ascites, and T1753C/A/G mutations.
Abstract: The SAE patients with T1753C/A/G mutations had a higher rate of acute-on-chronic liver failure (P = 0.006) and higher MELD score (P = 0.018) than those without T1753C/A/G mutations.
Next generation sequencing identifies baseline viral mutants associated with treatment response to pegylated interferon in HBeAg-positive chronic hepatitis B.
Abstract: Based on NGS, the prevalence of T1753V (T1753C/A/G) and A1762T/G1764A variants were significantly lower in responders compared to non-responders (8.3% vs.
Hepatitis B virus mutations, expression quantitative trait loci for PTPN12, and their interactions in hepatocellular carcinoma.
Discussion: A1762T, G1764A, and T1753C/A mutations in the BCP region, and G1613A and C1653T mutations in the Enh II region were reported more frequent in HCC patients 27.
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 chronic HBV infection.12 In vivo studies suggest that the TA mutant increases the replication capacity of HBV and suppresses HBeAg serum levels.13 A1762T/G1764A mutations are also predictors of postoperative survival in patients with HBV-related HCC.14 A1762T/T1764A<

Abstract: METHODS: A HBx combination (combo) mutant with changes in the CP region that corresponded to A1762T/G1764A (TA), T1753A, and T1768A was constructed and expressed in L-02 and Hep3B cells.
Entecavir vs. lamivudine in chronic hepatitis B patients with severe acute exacerbation and hepatic decompensation.
Introduction: Over the past few years, we defined that a high prevalence of the HBV C1 genotype, pre-S deletion and pre-S2 start codon mutation, C1653T, T1753A/G, C1766T, and T1768A mutations in the BCP/EnhII region, and A2159G, A2189C, and G2203W in the core gene are associated with HCC in Qidong.
Discussion: Another possibility to explain the rationality of A987G is that this mutation may be in linkage disequilibrium with other well-defined PMID: 23886144

Abstract: The prevalences of T1753C/A/G and A1762T/G1764A mutations in the basal core promotor (BCP) region were significantly higher in the HCC group compared to the non-HCC group.
