Genes affected

JAG2 (HGNC:6189): (jagged canonical Notch ligand 2) The Notch signaling pathway is an intercellular signaling mechanism that is essential for proper embryonic development. Members of the Notch gene family encode transmembrane receptors that are critical for various cell fate decisions. The protein encoded by this gene is one of several ligands that activate Notch and related receptors. Two transcript variants encoding different isoforms have been found for this gene.

Dec 12, 2023

The c.3689A>G (p.N1230S) alteration is located in exon 26 (coding exon 26) of the JAG2 gene. This alteration results from a A to G substitution at nucleotide position 3689, causing the asparagine (N) at amino acid position 1230 to be replaced by a serine (S). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
