Mutations in cardiac sodium channels: clinical implications.

Abstract excerpt

Voltage-gated sodium channels (VGSCs) are critical transmembrane proteins responsible for the rapid action potential upstroke in most excitable cells. Recently discovered mutations in VGSCs, which underlie idiopathic clinical disease, have emphasized the importance of these channels in tissues such as skeletal muscle, nervous system, and myocardium. Mutations in the gene encoding the cardiac sodium channel...
