Common questions in this guide

What is Alagille syndrome?
Alagille syndrome (ALGS) is a rare, multisystem genetic disorder. It primarily affects the development and function of the liver, heart, kidneys, and blood vessels.
Which specialists should be on my child's Alagille syndrome care team?
Because ALGS is a multisystem disorder, your child will need a multidisciplinary team. This typically includes a primary pediatrician, a hepatologist for liver care, a cardiologist for the heart, a nephrologist for the kidneys, and a medical geneticist.
Why does Alagille syndrome cause severe itching?
Severe itching, also known as pruritus, is a common symptom in children with Alagille syndrome. It is caused by liver involvement and reduced bile flow, and there are specific treatments available to help manage this discomfort.

This guide provides educational information about Alagille syndrome for parents and caregivers. Always consult your child's pediatric specialists for medical advice and personalized treatment decisions.
