Invitae RCV000706529 SCV000835586 uncertain significance Familial thoracic aortic aneurysm and aortic dissection 2018-04-27 criteria provided, single submitter clinical testing This variant has not been reported in the literature in individuals with TGFBR1-related disease. This sequence change replaces alanine with proline at codon 480 of the TGFBR1 protein (p.Ala480Pro). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and proline. This variant is not present in population databases (ExAC no frequency). Algorithms developed to predict the effect of missense changes on protein structure and function do not agree on the potential impact of this missense change (SIFT: "Tolerated"; PolyPhen-2: "Probably Damaging"; Align-GVGD: "Class C0"). In summary, the available evidence is currently insufficient to determine the role of this variant in disease. Therefore, it has been classified as a Variant of Uncertain Significance.
