Alagille syndrome (ALGS) is a multi-system hereditary disorder characterized by hepatic bile duct paucity and cardiovascular malformations including pulmonic stenosis/ peripheral pulmonary stenosis and tetralogy of Fallot. Affected individuals show typical facies and abnormal butterfly vertebrae as well. Mutations in the Notch pathway cause ALGS.
