Invitae | RCV001233390 | SCV001405981 | pathogenic | Glycogen storage disease, type II | 2023-10-14 | criteria provided, single submitter | clinical testing | This sequence change replaces aspartic acid, which is acidic and polar, with glycine, which is neutral and non-polar, at codon 404 of the GAA protein (p.Asp404Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Pompe disease (PMID: 24384324). In at least one individual the data is consistent with being in trans (on the opposite chromosome) from a pathogenic variant. It has also been observed to segregate with disease in related individuals. ClinVar contains an entry for this variant (Variation ID: 959950). 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 variant disrupts the p.Asp404 amino acid residue in GAA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 16433701, 22658377). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. For these reasons, this variant has been classified as Pathogenic. |
