Invitae RCV001065418 SCV001230374 uncertain significance Adams-Oliver syndrome 5 2022-03-03 criteria provided, single submitter clinical testing 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 not expected to disrupt NOTCH1 protein function. ClinVar contains an entry for this variant (Variation ID: 859334). This variant has not been reported in the literature in individuals affected with NOTCH1-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces arginine, which is basic and polar, with cysteine, which is neutral and slightly polar, at codon 1082 of the NOTCH1 protein (p.Arg1082Cys). 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.
Ambry Genetics RCV003283949 SCV004008091 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2023-04-28 criteria provided, single submitter clinical testing The p.R1082C variant (also known as c.3244C>T), located in coding exon 20 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 3244. The arginine at codon 1082 is replaced by cysteine, an amino acid with highly dissimilar properties. This amino acid position is conserved. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
