Invitae RCV001058144 SCV001222691 uncertain significance Dilated Cardiomyopathy, Recessive 2020-02-10 criteria provided, single submitter clinical testing 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. Algorithms developed to predict the effect of missense changes on protein structure and function output the following: SIFT: "Tolerated"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0". The threonine amino acid residue is found in multiple mammalian species, suggesting that this missense change does not adversely affect protein function. These predictions have not been confirmed by published functional studies and their clinical significance is uncertain. This variant has not been reported in the literature in individuals with PLEKHM2-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces alanine with threonine at codon 298 of the PLEKHM2 protein (p.Ala298Thr). The alanine residue is moderately conserved and there is a small physicochemical difference between alanine and threonine.
