JAG1

The jagged 1 protein encoded by JAG1 is the human homolog of the Drosophilia jagged protein. Human jagged 1 is the ligand for the receptor notch 1, the latter a human homolog of the Drosophilia jagged receptor notch. Mutations that alter the jagged 1 protein cause Alagille syndrome. Jagged 1 signalling through notch 1 has also been shown to play a role in hematopoiesis. [provided by RefSeq]

JAG1

Ligand for multiple Notch receptors and involved in the mediation of Notch signaling (PubMed:18660822, PubMed:20437614).
May be involved in cell-fate decisions during hematopoiesis (PubMed:9462510).
Seems to be involved in early and late stages of mammalian cardiovascular development. Inhibits myoblast differentiation (By similarity).
Enhances fibroblast growth factor-induced angiogenesis (in vitro).

Alagille syndrome 1 (ALGS1):
A form of Alagille syndrome, an autosomal dominant multisystem disorder. It is clinically defined by hepatic bile duct paucity and cholestasis in association with cardiac, skeletal, and ophthalmologic manifestations. There are characteristic facial features and less frequent clinical involvement of the renal and vascular systems.
Tetralogy of Fallot (TOF):
A congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. In this condition, blood from both ventricles (oxygen-rich and oxygen-poor) is pumped into the body often causing cyanosis.
Deafness, congenital heart defects, and posterior embryotoxon (DCHE):
An autosomal dominant disease characterized by mild to severe combined hearing loss, congenital heart defects, and posterior embryotoxon, a corneal abnormality consisting of a central collagen core surrounded by a thin layer of Descemets membrane and separated from the anterior chamber by a layer of endothelium. Congenital heart defects include tetralogy of Fallot, ventricular septal defect, or isolated peripheral pulmonic stenosis.
