Ambry Genetics	RCV002354983	SCV002648281	uncertain significance	Familial thoracic aortic aneurysm and aortic dissection	2024-05-05	criteria provided, single submitter	clinical testing	The p.T194I variant (also known as c.581C>T), located in coding exon 4 of the NOTCH1 gene, results from a C to T substitution at nucleotide position 581. The threonine at codon 194 is replaced by isoleucine, an amino acid with similar properties. This amino acid position is not well 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.
