LQT12; SNT1; TACIP1; dJ1187J4.5
The SNTA1 gene currently has no well-established disease association; however there is preliminary evidence supporting a correlation with autosomal dominant long QT syndrome (LQTS), type 12 (MedGen UID: 442824).

Invitae tests that include this gene:
Pathogenic SNTA1 variants are associated with an unknown percentage of clinical cases of LQTS.
The SNTA1 gene encodes the protein syntrophin, alpha 1, a scaffolding protein in both cardiac and skeletal muscle cells that interacts with an important cardiac sodium channel (SCN5A). The electrical activity of cardiac muscle is controlled by the movement of potassium, sodium, and calcium ions across cardiac muscle cell membranes. Pathogenic variants in genes that encode proteins that interact with sodium channels are known to cause 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.
