Alagille syndrome

Abstract

Alagille syndrome is a rare disorder with low physician awareness. It affects multiple organs and thus patient management involves several medical specialties. It is an autosomal dominant disorder with significant intrafamilial variability. The most frequent clinical manifestations are neonatal jaundice, chronic cholestasis as well as cardiac, ocular and skeletal malformations associated with characteristic facial features. Inherited mutations affect the Notch pathway. Although the molecular basis of Alagille syndrome is well defined, no specific targeted therapy exists.
