Labcorp Genetics (formerly Invitae), Labcorp RCV001364597 SCV001560754 uncertain significance Succinyl-CoA acetoacetate transferase deficiency 2020-04-06 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 sequence changes on RNA splicing suggest that this variant may create or strengthen a splice site, but this prediction has not been confirmed by published transcriptional studies. Algorithms developed to predict the effect of missense changes on protein structure and function are either unavailable or do not agree on the potential impact of this missense change (SIFT: "Deleterious"; PolyPhen-2: "Benign"; Align-GVGD: "Class C0"). This variant has been observed in individual(s) with clinical features of SCOT deficiency (https://journals.sagepub.com/doi/full/10.1177/2326409816651281#bibr9-2326409816651281). This variant is not present in population databases (ExAC no frequency). This sequence change replaces methionine with valine at codon 515 of the OXCT1 protein (p.Met515Val). The methionine residue is weakly conserved and there is a small physicochemical difference between methionine and valine.
