Labcorp Genetics (formerly Invitae), Labcorp RCV005199156 SCV005842301 likely pathogenic Fabry disease 2024-11-14 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 93 of the GLA protein (p.Asp93Gly). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individuals with Fabry disease (PMID: 8875188; external communications). Invitae Evidence Modeling of protein sequence and biophysical properties (such as structural, functional, and spatial information, amino acid conservation, physicochemical variation, residue mobility, and thermodynamic stability) indicates that this missense variant is expected to disrupt GLA protein function with a positive predictive value of 80%. Experimental studies have shown that this missense change affects GLA function (PMID: 21972175). This variant disrupts the p.Asp93 amino acid residue in GLA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 15712228, 15806320, 16595074, 18205205). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. In summary, the currently available evidence indicates that the variant is pathogenic, but additional data are needed to prove that conclusively. Therefore, this variant has been classified as Likely Pathogenic.
