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.
Pathophysiology
This condition is inherited in an autosomal dominant pattern.
Epidemiology and Demographics
The estimated prevalence of Alagille syndrome is 1 in every 70,000 live births.
Natural History, Complications and Prognosis
Mortality is approximately 10%, with vascular accidents, cardiac disease, and liver disease accounting for most of the deaths. Vascular anomalies account for 34% of the mortality in this population [1].
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.
