BACKGROUND: Hepatocellular carcinoma (HCC) is a model of diverse spectrum of cancers, since it is induced by well-known etiologies, mainly Hepatitis C virus (HCV) and Hepatitis B virus (HBV). Here we aimed to identify HCV-specific mutational signature and explored the link between the HCV-related regional variation in mutations rates and HCV-induced alterations in genome-wide chromatin organization. METHODS: To identify an HCV-specific mutational signature in HCC, we performed high-resolution targeted sequencing to detect passenger mutations on 64 HCC samples from three etiology groups - HBV, HCV, or other...
