Labcorp Genetics (formerly Invitae), Labcorp RCV001898924 SCV002175069 uncertain significance Glycogen storage disease XV; Polyglucosan body myopathy type 2 2022-04-23 criteria provided, single submitter clinical testing This sequence change replaces alanine, which is neutral and non-polar, with proline, which is neutral and non-polar, at codon 310 of the GYG1 protein (p.Ala310Pro). This variant is present in population databases (no rsID available, gnomAD 0.004%). This variant has not been reported in the literature in individuals affected with GYG1-related conditions. 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 proline amino acid residue is found in multiple mammalian species, which suggests that this missense change does not adversely affect protein function. 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.
