Abstract:
Alagille syndrome is an embryofoetopathy, due to mutations in the gene JAG1. It is autosomic dominant with variable expressivity, or sporadic. Neonatal cholestasis is a main feature, due to the paucity of intrahepatic bile ducts. It can rarely develop into cirrhosis, but be responsible for a disabling pruritus and xanthomas. The other features are a peculiar facies, cardiac abnormalities, butterfly vertebrae, and ocular embryotoxon. The prognosis depends on the severity of the liver and heart diseases. Hepatocarcinoma has been reported.

Gastritis can stem from various causes, each...
