Labcorp Genetics (formerly Invitae), Labcorp RCV002877500 SCV003239517 pathogenic Glycogen storage disease, type II 2022-10-13 criteria provided, single submitter clinical testing For these reasons, this variant has been classified as Pathogenic. 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. This missense change has been observed in individual(s) with Pompe disease (Invitae). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces proline, which is neutral and non-polar, with arginine, which is basic and polar, at codon 457 of the GAA protein (p.Pro457Arg).
