Core Tip

Core Tip: We describe two patients from consanguineous parents who had liver cirrhosis, were completely blind, and had familial mutations in the cytochrome P450 4V2 (CYP4V2) gene. The four other siblings of these patients were night-blind, and one also had cirrhosis. CYP4V2 functions in hepatic lipid metabolism and inflammatory responses. We suggest that this CYP4V2 gene mutation affects hepatic lipid metabolism and inflammatory responses, which leads to chronic liver injury and may subsequently progress to liver fibrosis and cirrhosis.
