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 NOTCH1 p.Cys359Cys variant was not identified in the literature nor was it identified in ClinVar or LOVD 3.0. The variant was identified in dbSNP (ID: rs202235419) and ClinVar (classified as a variant of uncertain significance by Invitae for Adams-Oliver syndrome 5). The variant was identified in control databases in 5 of 246920 chromosomes at a frequency of 0.00002025 (Genome Aggregation Database March 6, 2019, v2.1.1). The variant was observed in the following populations: East Asian in 3 of 18082 chromosomes (freq: 0.000166), South Asian in 1 of 30592 chromosomes (freq: 0.000033) and Latino in 1 of 34456 chromosomes (freq: 0.000029), but was not observed in the African, Ashkenazi Jewish, European (Finnish), European (non-Finnish), or Other populations. The p.Cys359Cys variant is not expected to have clinical significance because it does not result in a change of amino acid and is not located in a known consensus splice site, however 4 of 4 in silico or computational prediction software programs (SpliceSiteFinder, MaxEntScan, NNSPLICE, GeneSplicer) predict a greater than 10% difference in splicing and the creation of a new 5' splice site. However, this has not been confirmed through RNA analysis and is not predictive enough to assume pathogenicity. In summary, based on the above information the clinical significance of this variant cannot be determined with certainty at this time. This variant is classified as a variant of uncertain significance. -
