Alagille syndrome (AGS) is an autosomal dominant disorder caused by mutations in Jagged1 (JAG1), a ligand in the evolutionarily conserved Notch signaling pathway. Previous studies have demonstrated that a wide spectrum of JAG1 mutations result in AGS. These include total gene deletions, protein trun

Abstract
Congenital cardiac defects such as peripheral pulmonary stenosis are well described in Alagille syndrome (AGS), which is transmitted in an autosomal dominant inheritance. Haploinsufficiency of the Jagged1 (JAG1) gene has been shown to cause AGS. Abdominal coarctation is an uncommon vascular congenital anomaly which has been described only three times in AGS. Recently, expression of the Jagged1 gene has been found in the developing heart and in multiple associated vascular structures, including the descending aorta. Mutation analysis of the Jagged1 gene in this fourth reported patient with coarctation of the abdominal aorta in AGS and right subclavian stenosis identified a mutation deletion (1485 Del CT). This agrees with the Jagged1 expression studies and suggests that coarctation of aorta may be a component of AGS. Β© 2002 WileyβLiss, Inc.

Mutations in the human JAGGED1 gene cause Alagille syndrome, an autosomal dominant developmental disorder. The gene encodes a transmembrane protein which is a ligand of Notch receptors. We report 23 mutations in previously undescribed probands, including 15 novel mutations and 8 recurrent mutations.
