Ambry Genetics | RCV002315088 | SCV000739426 | uncertain significance | Familial thoracic aortic aneurysm and aortic dissection | 2016-05-24 | criteria provided, single submitter | clinical testing | The p.Y319C variant (also known as c.956A>G), located in coding exon 6 of the NOTCH1 gene, results from an A to G substitution at nucleotide position 956. The tyrosine at codon 319 is replaced by cysteine, an amino acid with highly dissimilar properties. This variant was not reported in population based cohorts in the following databases: Database of Single Nucleotide Polymorphisms (dbSNP), NHLBI Exome Sequencing Project (ESP), and 1000 Genomes Project. In the ESP, this variant was not observed in 6496 samples (12992 alleles) with coverage at this position. This amino acid position is well 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 variant remains unclear. |
