Uncertain significance, criteria provided, single submitterclinical testingLabcorp Genetics (formerly Invitae), LabcorpMay 25, 2022In 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 valine amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. This variant has not been reported in the literature in individuals affected with SGPL1-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.008%). This sequence change replaces alanine, which is neutral and non-polar, with valine, which is neutral and non-polar, at codon 11 of the SGPL1 protein (p.Ala11Val). -
