Alagille syndrome (AGS; Online Mendelian Inheritance in Man no. 118450) is a multisystem autosomal dominant disorder with highly variable expression characterized by chronic cholestasis caused by a paucity of interlobular bile ducts, skeletal abnormalities, peculiar facies, ocular abnormalities, and cardiovascular disorders. AGS is diagnosed almost exclusively in children in the setting of predominant liver manifestations or, more rarely, in their adult relatives. We report 2 patients in whom AGS was diagnosed in adulthood during the workup of renal disease in the absence of a well-defined familial history. Renal disease caused by AGS probably is underdiagnosed in adult patients.

Alagille syndrome (ALGS) is a multisystem autosomal dominant disorder in which patients may have characteristic facial features and involvement of the liver, heart, vessels, bones, eyes, kidneys and central nervous system. As there is little published data on ALGS in Africa, our aim was to describe the presentation and outcomes of ALGS in South Africa. The study constitutes a retrospective analysis of 25 patient medical records diagnosed as ALGS at Chris Hani Baragwanath Academic Hospital Pediatric Gastroenterology clinic between January 1992 and January 2020.

Pediatric cholestatic liver diseases are rare conditions that can result from multiple specific underlying etiologies. Among the most common etiologies of pediatric cholestatic liver diseases are biliary atresia, Alagille syndrome (ALGS), and inherited disorders of bile acid transport. These diseases are characterized by episodic or chronic unremitting cholestasis.

Background: Alagille syndrome (ALGS) is a rare disease. The variable clinical manifestations make the diagnosis of ALGS difficult. This study aimed to provide a basis for the early diagnosis of ALGS patients whose clinical identification is difficult and to enrich the spectrum of genetic variants implicated in Chinese children with ALGS.

Alagille syndrome (ALGS) is a rare, cholestatic multiorgan disease associated with bile duct paucity, leading to cholestasis. Clinical symptoms of cholestasis include debilitating pruritus, xanthomas, fat-soluble vitamin deficiencies, growth failure, renal disease and impaired health-related quality of life (HRQoL). The main objective was to review the current literature on the epidemiological, clinical, psychosocial and economic burden of ALGS in view of the development of ileal bile acid transporter (IBAT) inhibitors.
