Athena Diagnostics | RCV003482627 | SCV004229484 | pathogenic | not provided | 2023-08-30 | criteria provided, single submitter | clinical testing | This variant has been identified in at least one individual with clinical features associated with this gene. This variant has not been reported in large, multi-ethnic general populations (http://gnomad.broadinstitute.org). This variant alters a critical location within the protein, and is expected to severely affect function and cause disease. Greater than 90% of NOTCH3 pathogenic variants associated with CADASIL involve the gain or loss of a cysteine residue within the epidermal growth factor (EGF)-like repeat domain (PMID: 32457593, 20301673). |

RCV003482627 | SCV004565070 | likely pathogenic | not provided | 2023-03-31 | criteria provided, single submitter | clinical testing | The NOTCH3 c.1531T>A; p.Cys511Ser variant, to our knowledge, is not reported in the medical literature or gene specific databases. This variant is absent from the Genome Aggregation Database, indicating it is not a common polymorphism. Additionally, other amino acid substitutions at this codon (p.Cys511Arg, p.Cys511Phe, p.Cys511Tyr) have been reported in individuals with (CADASIL) and are considered pathogenic (Opherk 2004; Mosca 2011; Bianchi 2005). Computational analyses predict that this variant is deleterious (REVEL: 0.948). Most pathogenic NOTCH3 variants occur in exons 2-24 and either create or destroy a cysteine residue within an EGF-like domain (Rutten 2014), and thus the p.Cys511Ser variant is consistent with the predominant mechanism of disease in NOTCH3. Based on available information, this variant is considered to be likely pathogenic. References: Bianchi S et al. Gene symbol: Notch3. Disease: CADASIL. Hum Genet. 2005 Dec;118(3-4):546.
