Pathogenic Novel Heterozygous Variant c.1076c>T p. (Ser359Phe) chr1: 120512166 in NOTCH2 Gene, Type 2 Alagille Syndrome Causing Neonatal Cholestasis: A Case Report.

ABSTRACT: BACKGROUND Alagille syndrome (ALGS) is a multisystem hereditary illness with a dominant pattern and partial penetrance. Multiple organ abnormalities can be caused by mutations in the Jagged canonical Notch ligand 1 (JAG1) gene. Notch receptor 2 (NOTCH2) gene mutations are also uncommon. ALGS is also characterized by deformed or narrowed bile ducts and is notoriously difficult to diagnose due to the wide range of symptoms and absence of unambiguous genotype-phenotype connections. Little is known about ALGS patients who have NOTCH2 mutations. We present a patient who developed progressive liver failure due to a unique pathogenic heterozygous variation of the NOTCH2 gene, c.1076c>T p. (Ser359Phe) chr1: 120512166, resulting in type 2 ALGS.
