Invitae | RCV001309191 | SCV001498681 | uncertain significance | Brugada syndrome 8 | 2020-09-03 | criteria provided, single submitter | clinical testing | 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 with HCN4-related conditions. This variant is not present in population databases (ExAC no frequency). This sequence change replaces serine with threonine at codon 176 of the HCN4 protein (p.Ser176Thr). The serine residue is moderately conserved and there is a small physicochemical difference between serine and threonine. |
