Screening and diagnosis

Indications for testing: as per SIGENP 2022 guidelines, test for Alagille syndrome using specific tests before any invasive diagnostic procedure in infants with cholestasis, as it may mimic biliary atresia.

Liver biopsy: as per EASL 2024 guidelines, do not perform routine liver biopsy to determine the prognosis or for the management of liver disease in patients with Alagille syndrome.

Liver donation
As per AASLD/AST/NASPGHAN 2014 guidelines:
Consider using living donation from a first-degree family member for patients with Alagille syndrome, but obtain a careful donor evaluation with liver biopsy and/or cholangiography to rule out bile duct hypoplasia.
Obtain a careful evaluation of the donor for bile duct hypoplasia and vascular anomalies if the potential donor and recipient share the same mutant JAG1 or NOTCH2 allele, but do not perform living-related liver transplantation in most circumstances.
