Description

This sequence change replaces asparagine, which is neutral and polar, with serine, which is neutral and polar, at codon 493 of the DSG2 protein (p.Asn493Ser). This variant is present in population databases (rs375679311, gnomAD 0.03%). This missense change has been observed in individual(s) with arrhythmogenic right ventricular cardiomyopathy (PMID: 21606390). ClinVar contains an entry for this variant (Variation ID: 163212). 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) has been performed at Invitae for this missense variant, however the output from this modeling did not meet the statistical confidence thresholds required to predict the impact of this variant on DSG2 protein function. 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.
