RCV002923200 | SCV003268322 | uncertain significance | Early infantile epileptic encephalopathy with suppression bursts | 2022-10-15 | 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 KCNH5 protein function. This variant has not been reported in the literature in individuals affected with KCNH5-related conditions. This variant is present in population databases (no rsID available, gnomAD 0.001%). This sequence change replaces glutamine, which is neutral and polar, with lysine, which is basic and polar, at codon 956 of the KCNH5 protein (p.Gln956Lys). |
Ambry Genetics | RCV004983202 | SCV005600726 | uncertain significance | Inborn genetic diseases | 2024-10-16 | criteria provided, single submitter | clinical testing | The c.2866C>A (p.Q956K) alteration is located in exon 11 (coding exon 11) of the KCNH5 gene. This alteration results from a C to A substitution at nucleotide position 2866, causing the glutamine (Q) at amino acid position 956 to be replaced by a lysine (K). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. |
