Defective intracellular transport and processing of JAG1 missense mutations in Alagille syndrome

Abstract excerpt

Jagged1 (JAG1) is a cell surface ligand in the Notch signaling pathway and mutations in this gene cause Alagille syndrome (AGS). JAG1 mutations have been identified in 60-70% of AGS patients studied, and these include total gene deletions ( approximately 6%), protein-truncating mutations (insertions, deletions and nonsense mutations) (82%) and missense mutations (12%). Based on the finding that total JAG1...
