Cholestasis, benign recurrent intrahepatic, 2 (BRIC2)2 Publications

The disease is caused by mutations affecting the gene represented in this entry.

Disease descriptionA disorder characterized by intermittent episodes of cholestasis without progression to liver failure. There is initial elevation of serum bile acids, followed by cholestatic jaundice which generally spontaneously resolves after periods of weeks to months. The cholestatic attacks vary in severity and duration. Patients are asymptomatic between episodes, both clinically and biochemically.
