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.S417L variant (also known as c.1250C>T), located in coding exon 7 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 1250. The serine at codon 417 is replaced by leucine, an amino acid with dissimilar properties. This amino acid position is conserved. 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. -

NOTCH1 NM_017617.4 esxon 7 p.Ser417Leu (c.1250C>T): This variant has not been reported in the literature but is present in 0.008% (9/106554) of European alleles in the Genome Aggregation Database (https://gnomad.broadinstitute.org/variant/9-139412594-G-A). This variant is present in ClinVar (Variation ID:544189). Evolutionary conservation suggests that this variant may not impact the protein, but computational predicitve tools predict a deleterious effect. In summary, data on this variant is insufficient for disease classification. Therefore, the clinical significance of this variant is uncertain. -
