Genes affected

NOTCH1 (HGNC:7881): (notch receptor 1) This gene encodes a member of the NOTCH family of proteins. Members of this Type I transmembrane protein family share structural characteristics including an extracellular domain consisting of multiple epidermal growth factor-like (EGF) repeats, and an intracellular domain consisting of multiple different domain types. Notch signaling is an evolutionarily conserved intercellular signaling pathway that regulates interactions between physically adjacent cells through binding of Notch family receptors to their cognate ligands. The encoded preproprotein is proteolytically processed in the trans-Golgi network to generate two polypeptide chains that heterodimerize to form the mature cell-surface receptor. This receptor plays a role in the development of numerous cell and tissue types. Mutations in this gene are associated with aortic valve disease, Adams-Oliver syndrome, T-cell acute lymphoblastic leukemia, chronic lymphocytic leukemia, and head and neck squamous cell carcinoma.

The p.R2313Q variant (also known as c.6938G>A), located in coding exon 34 of the NOTCH1 gene, results from a G to A substitution at nucleotide position 6938. The arginine at codon 2313 is replaced by glutamine, an amino acid with highly similar properties. This alteration was reported in an individual with hypoplastic left heart syndrome and classified as variant of unknown significance (Kerstjens-Frederikse WS et al. Genet. Med., 2016 Sep;18:914-23). This amino acid position is well conserved in available vertebrate species; however, glutamine is the reference amino acid in other vertebrate species. In addition, the in silico prediction for this alteration is inconclusive. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. -
