GeneDx RCV000484104 SCV000572510 uncertain significance not provided 2024-04-04 criteria provided, single submitter clinical testing Not observed at significant frequency in large population cohorts (gnomAD); In silico analysis indicates that this missense variant does not alter protein structure/function; Has not been previously published as pathogenic or benign to our knowledge
Labcorp Genetics (formerly Invitae), Labcorp RCV003631124 SCV004372732 uncertain significance Arrhythmogenic right ventricular dysplasia 10 2023-07-03 criteria provided, single submitter clinical testing This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with serine, which is neutral and polar, at codon 319 of the DSG2 protein (p.Gly319Ser). This variant has not been reported in the literature in individuals affected with DSG2-related conditions. 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. 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 not expected to disrupt DSG2 protein function. ClinVar contains an entry for this variant (Variation ID: 422911).
