RCV001841177 | SCV001360326 | pathogenic | Cardiac arrhythmia | 2019-10-14 | criteria provided, single submitter | clinical testing | This variant deletes 1 nucleotide in exon 2 (coding exon 1) of the SCN5A gene, creating a frameshift and premature translation stop signal. This variant is expected to result in an absent or non-functional protein product. 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 not been identified in the general population by the Genome Aggregation Database (gnomAD). Loss of SCN5A function is a known mechanism of disease. Based on the available evidence, this variant is classified as Pathogenic. |
| Invitae | RCV003688923 | SCV004433699 | pathogenic | not provided | 2023-09-25 | criteria provided, single submitter | clinical testing | This sequence change creates a premature translational stop signal (p.Lys63Asnfs*34) in the SCN5A gene. It is expected to result in an absent or disrupted protein product. Loss-of-function variants in SCN5A are known to be pathogenic (PMID: 20129283, 22789973). This variant is not present in population databases (gnomAD no frequency). 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: 928434). For these reasons, this variant has been classified as Pathogenic. |
