RCV001841095 | SCV001357226 | uncertain significance | Cardiac arrhythmia | 2019-12-31 | criteria provided, single submitter | clinical testing | This missense variant replaces serine with asparagine at codon 1996 of the SCN5A protein. Computational prediction suggests that this variant may not impact protein structure and function (internally defined REVEL score threshold <= 0.5, PMID: 27666373). Splice site prediction tools suggest that this variant may not impact RNA splicing. To our knowledge, functional studies have not been performed for this variant. This variant has not been reported in individuals affected with cardiovascular disorders in the literature. This variant has been identified in 1/206324 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 | RCV002356857 | SCV002655715 | uncertain significance | Cardiovascular phenotype | 2020-05-28 | criteria provided, single submitter | clinical testing | The p.S1996N variant (also known as c.5987G>A), located in coding exon 27 of the SCN5A gene, results from a G to A substitution at nucleotide position 5987. The serine at codon 1996 is replaced by asparagine, an amino acid with highly similar properties. This amino acid position is well conserved in available vertebrate species. In addition, this alteration is predicted to be tolerated by in silico analysis. Since supporting evidence is limited at this time, the clinical significance of this alteration remains unclear. |
