Diagnosis of Alagille Syndrome—25 Years of Experience at King's College Hospital

Abstract

Clinical features of AGS are not as consistently informative as suggested in the literature. Hypercholesterolaemia is nonspecific but may be a helpful pointer. Histology is not characteristic in 25%; hepatobiliary iminodiacetic acid scan and ultrasound may suggest a false diagnosis of biliary atresia in 60% and 28%, respectively, supporting the concept that infants with liver disease warrant early referral to a specialist centre. The advent of genetic diagnosis will redefine the syndrome with likely effects on the prognosis of the defined group.
