| Athena Diagnostics | RCV000516189 | SCV000614248 | pathogenic | not provided | 2020-07-22 | criteria provided, single submitter | clinical testing | The frequency of this variant in the general population is consistent with pathogenicity (http://gnomad.broadinstitute.org). This variant has been identified in at least one individual with clinical features associated with this gene. This variant alters a critical location within the protein, and is expected to severely affect function and cause disease. Greater than 90% of pathogenic variants identified in NOTCH3 involve the gain or loss of a cysteine residue within the epidermal growth factor (EGF)-like repeat domain |

RCV000516189 | SCV003443220 | uncertain significance | not provided | 2022-05-28 | criteria provided, single submitter | clinical testing | This sequence change replaces glycine, which is neutral and non-polar, with cysteine, which is neutral and slightly polar, at codon 667 of the NOTCH3 protein (p.Gly667Cys). This variant is present in population databases (no rsID available, gnomAD 0.0009%). This missense change has been observed in individual(s) with cerebral arteriopathy with subcortical infarcts and leukoencephalopathy 1 (CADASIL) (PMID: 22664156). ClinVar contains an entry for this variant (Variation ID: 447805). Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Possibly Damaging"; Align-GVGD: "Class C15"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance. |
