RCV001550377 | SCV000291820 | uncertain significance | not provided | 2024-09-14 | criteria provided, single submitter | clinical testing | This sequence change replaces glutamic acid, which is acidic and polar, with lysine, which is basic and polar, at codon 1823 of the SCN5A protein (p.Glu1823Lys). This variant is present in population databases (rs760837591, gnomAD 0.01%). This variant has not been reported in the literature in individuals affected with SCN5A-related conditions. ClinVar contains an entry for this variant (Variation ID: 242204). An algorithm developed to predict the effect of missense changes on protein structure and function (PolyPhen-2) suggests that this variant is likely to be tolerated. 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. |

RCV001843006 | SCV001357073 | uncertain significance | Cardiac arrhythmia | 2023-06-08 | criteria provided, single submitter | clinical testing | This missense variant replaces glutamic acid with lysine at codon 1823 of the SCN5A protein. Computational prediction is inconclusive regarding the impact of this variant on protein structure and function (internally defined REVEL score threshold 0.5 < inconclusive < 0.7, PMID: 27666373). To our knowledge, functional studies have not been reported for this variant. This variant has not been reported in individuals affected with SCN5A-related disorders in the literature. This variant has been identified in 3/281038 chromosomes in the general population by the Genome Aggregation Database (gnomAD). The available evidence is insufficient to determine the role of this variant in disease conclusively. Therefore, this variant is classified as a Variant of Uncertain Significance. |

Ambry Genetics | RCV002347919 | SCV002653860 | uncertain significance | Cardiovascular phenotype | 2022-08-18 | criteria provided, single submitter | clinical testing | The p.E1823K variant (also known as c.5467G>A), located in coding exon 27 of the SCN5A gene, results from a G to A substitution at nucleotide position 5467. The glutamic acid at codon 1823 is replaced by lysine, an amino acid with similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be deleterious by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
