Invitae RCV000226349 SCV000291189 uncertain significance Aortic aneurysm, familial thoracic 7 2016-02-15 criteria provided, single submitter clinical testing This sequence change replaces alanine with glycine at codon 467 of the MYLK protein (p.Ala467Gly). The alanine residue is weakly conserved and there is a small physicochemical difference between alanine and glycine. This variant is not present in population databases (ExAC no frequency) and has not been reported in the literature in individuals with a MYLK-related disease. 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: "Possibly Damaging"; Align-GVGD: "Class C0"). However, the glycine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. In summary, this is a novel missense change with uncertain impact on protein function. It has been classified as a Variant of Uncertain Significance.
