Mutated SCN5A activates BrS. 2 / 2
| 2

reach
"The primary pathophysiological mechanism underlying BrS is driven by SCN5A mutations, resulting in the loss of function (LoF) of the late cardiac sodium current (INa)."

reach
"For instance, SCN5A mutations can cause not only LQT3 and BrS, but also cardiac conduction disease, sick sinus syndrome, atrial fibrillation, or dilated cardiomyopathy."
