GeneDx RCV000492876 SCV000582265 uncertain significance not provided 2017-04-28 criteria provided, single submitter clinical testing A variant of uncertain significance has been identified in the NOTCH1 gene. The R938W variant has not been published as pathogenic or been reported as benign to our knowledge. This variant is observed in 0.1-0.2% of alleles from individuals of South Asian ancestry in large population cohorts (Lek et al., 2016; 1000 Genomes Consortium et al., 2015; Exome Variant Server). The R938W variant is a non-conservative amino acid substitution, which is likely to impact secondary protein structure as these residues differ in polarity, charge, size and/or other properties. Moreover, in silico analysis predicts this variant is probably damaging to the protein structure/function. Nevertheless, this substitution occurs at a position that is not conserved.
Ambry Genetics RCV000143939 SCV000739363 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2017-06-23 criteria provided, single submitter clinical testing The p.R938W variant (also known as c.2812C>T), located in coding exon 18 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 2812. The arginine at codon 938 is replaced by tryptophan, an amino acid with dissimilar properties. This amino acid position is poorly conserved in available vertebrate species. 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.
