Labcorp Genetics (formerly Invitae), Labcorp RCV003706318 SCV004490330 uncertain significance not provided 2022-12-31 criteria provided, single submitter clinical testing This sequence change replaces cysteine, which is neutral and slightly polar, with arginine, which is basic and polar, at codon 986 of the NOTCH3 protein (p.Cys986Arg). The frequency data for this variant in the population databases is considered unreliable, as metrics indicate poor data quality at this position in the gnomAD database. This missense change has been observed in individual(s) with CADASIL (PMID: 24840674). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt NOTCH3 protein function. 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.
