Familial thoracic aortic aneurysm and aortic dissection Uncertain:1

Ambry Genetics
Significance:Uncertain significance
Review Status:criteria provided, single submitter
Collection Method:clinical testing

The p.T472I variant (also known as c.1415C>T), located in coding exon 4 of the SLC2A10 gene, results from a C to T substitution at nucleotide position 1415. The threonine at codon 472 is replaced by isoleucine, an amino acid with similar 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. -
