Genes affected
SCN5A (HGNC:10593): (sodium voltage-gated channel alpha subunit 5) The protein encoded by this gene is an integral membrane protein and tetrodotoxin-resistant voltage-gated sodium channel subunit. This protein is found primarily in cardiac muscle and is responsible for the initial upstroke of the action potential in an electrocardiogram. Defects in this gene have been associated with long QT syndrome type 3 (LQT3), atrial fibrillation, cardiomyopathy, and Brugada syndrome 1, all autosomal dominant cardiac diseases. Alternative splicing results in several transcript variants encoding different isoforms. [provided by RefSeq, May 2022]

Brugada syndrome Pathogenic:1
Pathogenic, criteria provided, single submitter | clinical testing | Invitae | Dec 19, 2015 | This sequence change deletes 13 nucleotides and inserts 11 nucleotides in exon 17 of the SCN5A mRNA (c.3142_3154delCCCATCGCTGTGinsTCTGACTGTGT) causing a frameshift at codon 1048. This creates a premature translational stop signal (p.Pro1048Serfs*10) and is expected to result in an absent or disrupted protein product. While this particular variant has not been reported in the literature, truncating variants in SCN5A are known to be pathogenic (PMID: 20129283, 22789973). For these reasons, this variant has been classified as Pathogenic. - |
