Alagille syndrome is a rare genetic disorder that primarily affects the liver and heart, but can also involve the eyes, skeleton, kidneys, and blood vessels. It is characterized by a reduced number of bile ducts inside the liver (bile duct paucity), which leads to impaired bile flow (cholestasis) and progressive liver damage. Affected individuals often present in infancy or early childhood with jaundice, itching, and growth failure, though the severity varies widely—even among members of the same family. The syndrome is named after the French pediatrician Daniel Alagille, who first described it in 1969. WikipediaMedlinePlus
In addition to liver involvement, Alagille syndrome frequently causes congenital heart defects—most commonly narrowing of the pulmonary valves or blood vessels leading from the heart (pulmonic stenosis) and, in some cases, tetralogy of Fallot. Distinctive facial features such as a broad forehead, deep-set eyes, and a pointed chin are often noted. Other manifestations can include butterfly-shaped vertebrae, posterior embryotoxon in the eyes, renal anomalies, and vascular irregularities in the brain and kidney. The clinical picture is multisystemic and highly variable, requiring a coordinated, multidisciplinary approach to diagnosis and management. MedlinePlus
Types
Alagille syndrome is classified into two genetic types based on the underlying mutation:
Type 1 (JAG1-related): Accounts for about 94–97% of cases and is caused by mutations or deletions in the JAG1 gene, which encodes the Notch signaling ligand Jagged1.
Type 2 (NOTCH2-related): Represents roughly 2–3% of cases and involves mutations in the NOTCH2 gene, which encodes the Notch receptor.
Both types follow an autosomal dominant inheritance pattern, though about 60% of cases arise from new (de novo) mutations rather than inheritance from an affected parent. Clinical variability is substantial, even among individuals with the same genetic variant. NaturePMC
Causes
1. JAG1 Gene Mutations
Most cases of Alagille syndrome result from pathogenic variants in the JAG1 gene on chromosome 20. These mutations disrupt the Jagged1 ligand, impairing Notch signaling necessary for the normal development of bile ducts, heart structures, and other organs. Nature
2. NOTCH2 Gene Mutations
A smaller subset of patients has mutations in the NOTCH2 gene, which encodes a receptor in the same pathway. These variants similarly impair Notch signaling and produce an overlapping clinical picture. Nature
3. Autosomal Dominant Inheritance
Alagille syndrome follows an autosomal dominant pattern, meaning a single copy of the mutated gene (from either parent) is sufficient to cause the disease. Affected parents have a 50% chance of passing the mutation to each child. Wikipedia
4. De Novo Mutations
Approximately 60% of cases arise from spontaneous (de novo) mutations that occur in the egg or sperm, without any family history of the disorder. Nature
5. Parental Germline Mosaicism
In a minority of families, an unaffected parent may carry the mutation in some of their germ cells (sperm or eggs) without showing symptoms, leading to more than one affected child despite no overt family history. Nature
6. Haploinsufficiency
Many pathogenic variants result in haploinsufficiency, where one normal copy of JAG1 or NOTCH2 is insufficient to maintain proper Notch signaling, leading to disease manifestations. Nature
7. Missense Mutations
Some JAG1 or NOTCH2 mutations change a single amino acid (missense), disrupting protein structure or receptor–ligand interactions essential for cell signaling. Nature
8. Nonsense Mutations
Variants that introduce a premature “stop” signal (nonsense mutations) truncate the Jagged1 or Notch2 protein, usually eliminating its function entirely. Nature
9. Frameshift Mutations
Insertions or deletions that shift the reading frame of the gene often produce nonfunctional proteins due to extensive missense translation and early termination. Nature
10. Splice‐Site Mutations
Mutations affecting the regions where the gene’s coding segments are joined (splice sites) can lead to improper mRNA processing and abnormal protein products. Nature
11. Large Gene Deletions
Rare cases involve larger deletions that remove part or all of the JAG1 gene, completely abolishing Jagged1 production. Wikipedia
12. Copy Number Variations
Submicroscopic duplications or deletions affecting JAG1 can also disrupt normal gene dosage and Notch pathway balance. Wikipedia
13. Modifier Gene Variants
Variations in other genes may modify the severity of Alagille features by enhancing or mitigating Notch pathway effects, contributing to the wide phenotypic range. Rare Disease Advisor
14. Epigenetic Changes
Alterations in DNA methylation or histone modification may influence how the JAG1 or NOTCH2 genes are expressed, potentially affecting disease severity. Nature
15. Environmental Factors
Although the core cause is genetic, in utero environmental exposures (e.g., maternal medications or toxins) might influence the development of organ systems already predisposed by Notch pathway defects. Nature
