Genes affected

NOTCH3 (HGNC:7883): (notch receptor 3) This gene encodes the third discovered human homologue of the Drosophilia melanogaster type I membrane protein notch. In Drosophilia, notch interaction with its cell-bound ligands (delta, serrate) establishes an intercellular signalling pathway that plays a key role in neural development. Homologues of the notch-ligands have also been identified in human, but precise interactions between these ligands and the human notch homologues remains to be determined. Mutations in NOTCH3 have been identified as the underlying cause of cerebral autosomal dominant arteriopathy with subcortical infarcts and leukoencephalopathy (CADASIL).

Uncertain significance, criteria provided, single submitter	clinical testing	ARUP Laboratories, Molecular Genetics and Genomics, ARUP Laboratories	Apr 28, 2022	The NOTCH3 c.2437G>A; p.Glu813Lys variant (rs375873637), to our knowledge, is not reported in the medical literature in an affected individual, but is reported in ClinVar (Variation ID: 447811). This variant is found in the African/African-American population with an allele frequency of 0.06% (14/24,936 alleles) in the Genome Aggregation Database. The glutamic acid at codon 813 is highly conserved, occurs in an EGF-like domain, and computational analyses predict that this variant is deleterious (REVEL: 0.89). In support of this prediction, computational modeling indicates this vriant may alter the protein structure (Vlachakis 2014). Most pathogenic NOTCH3 variants occur in exons 2-24 and either create or destroy a cysteine residue within an EGF-like domain (Rutten 2014). However, there are several amino acid substitutions not involving cysteine that may be disease-associated (Muino 2017). Due to limited information, the clinical significance of the p.Glu813Lys variant is uncertain at this time. References: Muino E et al.
