ATFB13; BRGDA5; GEFSP1
The SCN1B gene is associated with autosomal dominant genetic epilepsy with febrile seizures (GEFS+) (MedGen UID: 348994). Additionally, the SCN1B gene has preliminary evidence supporting a correlation with autosomal dominant Brugada syndrome (BrS) (MedGen UID: 411607), atrial fibrillation (MedGen UID: 334469), cardiac conduction disease (PMID: 18464934) and autosomal recessive early infantile epileptic encephalopathy (PMID: 19710327).

Pathogenic variants in SCN1B gene are associated with <5% of generalized epilepsy with febrile seizures, plus. Pathogenic SCN1B variants are also associated with an unknown percentage of clinical cases of BrS.
The SCN1B gene encodes the beta subunit of the sodium channel, voltage-gated, type I. Sodium channels control the flow of sodium ions in both muscle cells and neuronal 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 associated with inherited cardiac arrhyhtmias and inherited epilepsy/seizure disorders.
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.
