Background & Aims: A single nucleotide polymorphism (rs12979860 C/T) 3 kb upstream of the interleukin 28B (IL-28B) gene was shown to be associated with hepatitis C clearance. We verified whether this association also translates into a different genotype distribution at the end of the disease trajectory.Methods: A RFLP-PCR technique was used to genotype 412 patients with cirrhosis due to hepatitis C (n = 199), hepatitis B (n = 75), alcohol (n = 110), and other causes (n = 28), of whom 256 underwent liver transplantation (OLT). Hepatocellular carcinoma (HCC) was demonstrated in the native liver of 85 OLT patients, 52 with viral cirrhosis, and 33 with non-viral cirrhosis respectively. A group of 292 patients (235 HCV and 57 HBV positive) with mild chronic hepatitis and 344 healthy subjects served as controls.Results: A significant difference (p = 0.0005) was observed in IL-28B rs12979860 genotype frequencies between patients with viral cirrhosis (C/C = 99, C/T = 137, T/T = 38) and those with non-viral cirrhosis (C/C = 72, C/T = 58, T/T = 8). Patients with HCV related cirrhosis carried more frequently the T/T genotype in comparison to mild hepatitis C or HBV-related cirrhosis. IL-28B rs12979860 genotype frequencies were C/C = 23, C/T = 50, T/T = 12 among OLT patients with cirrhosis complicated by HCC, and C/C = 79, C/T = 78, T/T = 14 among patients with cirrhosis not complicated by HCC (p
