Species: Homo sapiens
About SCN5A
This gene has 11 transcripts (splice variants), 94 orthologues, 26 paralogues and is associated with 18 phenotypes. Restricted expression toward heart (RPKM 17.6).
Summary
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]
