The Alagille Syndrome (SAG), known as syndromic ductular paucity, is a multisystemic hereditary disorder of autosomal dominant transmission with a prevalence of 1/70000 live births. SAG is caused by a mutation in the Jagged1 gene (JAG1), a ligand encoding a Notch receptor that plays an important role in determining the fate of the developing cell.
