Invitae RCV001868966 SCV002293303 uncertain significance Glycogen storage disease, type II 2022-03-18 criteria provided, single submitter clinical testing This sequence change replaces glutamic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 655 of the GAA protein (p.Glu655Gly). This variant is not present in population databases (gnomAD no frequency). This variant has not been reported in the literature in individuals affected with GAA-related conditions. ClinVar contains an entry for this variant (Variation ID: 596019). Advanced modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) performed at Invitae indicates that this missense variant is expected to disrupt GAA 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.
