Management of Steatorrhea in Children and Young Adults With Alagille Syndrome After Liver Transplantation

The goal of this clinical trial is to learn if PERTZYE® works to treat steatorrhea in children and adults with Alagille Syndrome (ALGS) post liver transplant. It will also learn about the safety of PERTZYE®. The main questions it aims to answer are: * Does PERTZYE improve dietary fat absorption? * Does PERTZYE improve stool frequency and consistency? * Does PERTZYE improve abdominal signs and symptoms? * What medical problems do participants have when taking PERTZYE? Researchers will compare the results when participants are taking and stop taking PERTZYE. During the study, participants will: * Consume a high fat diet * Take PERTZYE every day with meals and snacks for up to 4 weeks * Have scheduled checkups by phone or video by clinical staff * Keep a diary of their symptoms and PERTZYE dosing * Collect stool for laboratory testing
