Alagille syndrome is an inherited disorder in which a person has fewer than the normal number of small bile ducts inside the liver. It is a complex disorder that can affect other parts of the body including the heart, kidneys, blood vessels, eyes, face, and skeleton.[1] Symptoms, including jaundice, pale, loose stools, and poor growth, typically develop in the first 2 years of life.[1][2] Symptoms and symptom severity varies, even among people in the same family.[1] Alagille syndrome is caused by mutations in the JAG1 and NOTCH2 genes. It is inherited in an autosomal dominant pattern.[3] Treatment is symptomatic and supportive. In severe cases, liver transplant may be necessary.[1]
