Accordingly, the frequency of the CXCL1 rs4074 A allele was significantly higher in the cirrhotic patients than in the subjects without cirrhosis (41.4% vs. 33.9%, OR=1.38, 95% CI:1.14-1.66, p=0.001).
Enhanced production of CXCL1 in response to HCV antigens in carriers of the rs4074 A allele together with its increased frequency in cirrhotic patients with hepatitis C suggest the CXCL1 rs4074 A allele as a genetic risk factor for cirrhosis progression in hepatitis C.
