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 c.4066C>T (p.R1356C) alteration is located in exon 25 (coding exon 25) of the NOTCH1 gene. This alteration results from a C to T substitution at nucleotide position 4066, causing the arginine (R) at amino acid position 1356 to be replaced by a cysteine (C). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -

A variant of uncertain significance has been identified in the NOTCH1 gene. The R1356C variant has been published in one European individual from a cohort of individuals with no known personal or family history indicative of a cancer predisposition syndrome who underwent whole genome sequencing (Bodian et al., 2014), although additional clinical details unrelated to cancer history were not described. The R1356C variant is also not observed in large population cohorts (Lek et al., 2016). The R1356C variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. In-silico analyses, including protein predictors and evolutionary conservation, support a deleterious effect. However, this variant has not been observed in a significant number of affected individuals, and it lacks both segregation and functional studies which would further clarify its pathogenicity. -
