Labcorp Genetics (formerly Invitae), Labcorp RCV005071971 SCV005697907 uncertain significance Fabry disease 2024-10-28 criteria provided, single submitter clinical testing This sequence change replaces tyrosine, which is neutral and polar, with serine, which is neutral and polar, at codon 216 of the GLA protein (p.Tyr216Ser). This variant is not present in population databases (gnomAD no frequency). This missense change has been observed in individual(s) with Fabry disease (PMID: 31860127). 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%. This variant disrupts the p.Tyr216 amino acid residue in GLA. Other variant(s) that disrupt this residue have been determined to be pathogenic (PMID: 19941952, 20367968, 27560961, 28756410). This suggests that this residue is clinically significant, and that variants that disrupt this residue are likely to be disease-causing. 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.
