Conditions We Treat
Alagille syndrome is a genetic disorder. It causes problems throughout the body, but one of the common signs is liver damage due to problems with the liver’s bile ducts. Instead of transporting bile away from the liver to other parts of the body, these problems cause bile to build up in the liver and damage it.
