The SCN5A gene is associated with autosomal dominant Brugada syndrome (BrS) (MedGen UID: 468523), long QT syndrome (LQTS), type 3 (MedGen UID: 349087), dilated cardiomyopathy (DCM) (MedGen UID: 331341) and atrial fibrillation (MedGen UID: 462814). Other SCN5A-related conditions have been reported (OMIM: 600163).

Invitae tests that include this gene:
Pathogenic SCN5A variants cause 15%-30% of cases of BrS and 5% of cases of LQTS. Pathogenic SCN5A variants are a rare cause of DCM and are associated with an unknown percentage of atrial fibrillation.
The SCN5A gene encodes the alpha unit of the sodium channel protein type 5. Sodium channels control the flow of sodium ions in cardiac muscle cells. The electrical activity of cardiac muscle is controlled by the movement of potassium, sodium and calcium ions across cardiac muscle cell membranes. Mutations in genes that disrupt the function of a sodium channel are a common cause of inherited cardiac arrhythmias.
Invitae is a College of American Pathologists (CAP)-accredited and Clinical Laboratory Improvement Amendments (CLIA)-certified clinical diagnostic laboratory performing full-gene sequencing and deletion/duplication analysis using next-generation sequencing technology (NGS).
Our sequence analysis covers clinically important regions of each gene, including coding exons, +/- 10 base pairs of adjacent intronic sequence in the transcript listed below. In addition, analysis covers the select non-coding variants specifically defined in the table below. Any variants that fall outside these regions are not analyzed. Any specific limitations in the analysis of these genes are also listed in the table below.
Our analysis detects most intragenic deletions and duplications at single exon resolution. However, in rare situations, single-exon copy number events may not be analyzed due to inherent sequence properties or isolated reduction in data quality. If you are requesting the detection of a specific single-exon copy number variation, please contact Client Services before placing your order.
