Invitae RCV001050282 SCV001214381 uncertain significance Brugada syndrome 8 2022-08-29 criteria provided, single submitter clinical testing ClinVar contains an entry for this variant (Variation ID: 846869). 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 HCN4 protein function. This variant has not been reported in the literature in individuals affected with HCN4-related conditions. This variant is not present in population databases (gnomAD no frequency). This sequence change replaces glycine, which is neutral and non-polar, with arginine, which is basic and polar, at codon 83 of the HCN4 protein (p.Gly83Arg).
