Ambry Genetics	RCV002372300	SCV002667379	uncertain significance	Familial thoracic aortic aneurysm and aortic dissection	2023-05-12	criteria provided, single submitter	clinical testing	The p.S225W variant (also known as c.674C>G), located in coding exon 4 of the NOTCH1 gene, results from a C to G substitution at nucleotide position 674. The serine at codon 225 is replaced by tryptophan, an amino acid with highly dissimilar properties. This amino acid position is highly conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear.
