Overview
Alagille syndrome is a multisystem genetic disorder that affects the liver, heart, eyes,face, skeleton, kidneys and vascular system. Problems associated with the disorder generally become evident in infancy or early childhood. The patients have a characteristic facial appearance. The disorder is inherited in an autosomal dominant pattern, and the estimated prevalence of Alagille syndrome is 1 in every 70,000 live births. The clinical features are highly variable even within the family.
Alagille syndrome can be associated with congenital heart disease, particularly Tetralogy of Fallot. The kidneys and central nervous system may also be affected. Cases of unilateral coronal craniosynostosis have also been described in association with this syndrome.
Diagnosis
The diagnosis is primarily clinical.
Treatment
There is no known cure for Alagille's Syndrome. Most of the treatments available are aimed at improving the functioning of the heart, and reducing the effects of impaired liver function.
