Color Diagnostics, LLC DBA Color Health RCV001841101 SCV001357534 likely pathogenic Cardiac arrhythmia 2020-02-12 criteria provided, single submitter clinical testing This variant deletes 1 nucleotide in exon 28 of the SCN5A gene, creating a frameshift and premature translation stop signal in the last exon. This mutant transcript is predicted to escape nonsense-mediated decay and be expressed as a truncated protein. To our knowledge, 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). Truncating variants occurring downstream of this variant have been reported in individuals affected with long QT syndrome (Clinvar). Loss of SCN5A function is a known mechanism of disease. Based on the available evidence, this variant is classified as Likely Pathogenic.
