Hepatitis C virus Genotype 1a core gene nucleotide patterns associated with hepatocellular carcinoma risk.

ABSTRACT: Specific sequence changes in codons 70 and 91 of the hepatitis C virus genotype 1b (HCV GT1b) core gene have been associated with increased risk of hepatocellular carcinoma (HCC). Essentially all previous studies were conducted in Asian populations with a wide range of liver disease, and none were conducted specifically in GT1a-infected individuals. We conducted a pilot study in a multiethnic population in the USA with HCV-related cirrhosis to determine if this association extended to GT1a-infected individuals and to determine if other sequence changes in the HCV core gene were associated with HCC risk. HCV core gene sequences from sera of 90 GT1 HCV carriers with cirrhosis (42 with HCC) were analysed using standard RT-PCR-based procedures. Nucleotide sequence data were compared with refer
