Ultrasensitive quantification of hepatitis B virus A1762T/G1764A mutant by a SimpleProbe PCR using a wild-type-selective PCR blocker and a primer-blocker-probe partial-overlap approach.

Abstract excerpt

Hepatitis B virus (HBV) carrying the A1762T/G1764A double mutation in the basal core promoter (BCP) region is associated with HBe antigen seroconversion and increased risk of liver cirrhosis and hepatocellular carcinoma (HCC). Quantification of the mutant viruses may help in predicting the risk of HCC. However, the viral genome tends to have nucleotide polymorphism, which makes it difficult to design...
