Invitae | RCV001367493 | SCV001563845 | uncertain significance | Brugada syndrome 8 | 2022-09-07 | 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 expected to disrupt HCN4 protein function. ClinVar contains an entry for this variant (Variation ID: 1058362). This variant has not been reported in the literature in individuals affected with HCN4-related conditions. This variant is present in population databases (rs745346676, gnomAD 0.006%). This sequence change replaces serine, which is neutral and polar, with leucine, which is neutral and non-polar, at codon 365 of the HCN4 protein (p.Ser365Leu). |

RCV003405614 | SCV004115701 | uncertain significance | HCN4-related condition | 2023-02-14 | criteria provided, single submitter | clinical testing | The HCN4 c.1094C>T variant is predicted to result in the amino acid substitution p.Ser365Leu. To our knowledge, this variant has not been reported in the literature. This variant is reported in 0.0033% of alleles in individuals of South Asian descent in gnomAD (http://gnomad.broadinstitute.org/variant/15-73635841-G-A). At this time, the clinical significance of this variant is uncertain due to the absence of conclusive functional and genetic evidence. |
