Alagille Syndrome (ALGS) – Market Outlook, Epidemiology, Competitive Landscape, and Market Forecast Report – 2023 To 2033

Alagille syndrome (ALGS), identified by OMIM 118450, is an autosomal dominant disorder linked to Notch signaling pathway abnormalities. It affects various systems, including the liver, heart, skeleton, eyes, kidneys, and central nervous system, often exhibiting distinct facial features. Most cases (about 97%) stem from JAG1 gene haploinsufficiency on 20p11.2-20p12 (encoding JAGGED1), caused primarily by mutations or deletions. A smaller fraction (<1%) arises from NOTCH2 mutations, which may lead to more frequent renal malformations. New mutations (approximately 60%) are common, and germline mosaicism rates are relatively high. Key clinical features of ALGS encompass bile duct paucity in liver biopsy, cholestasis, congenital heart defects (mainly pulmonary artery involvement), butterfly vertebrae, ophthalmic anomalies (most commonly posterior embryotoxon), and distinct facial characteristics. Additional manifestations may include renal irregularities, growth failure, development...
