Computational Study to Identify the Effects of the KCNJ2 E299V Mutation in Cardiac Pumping Capacity.

Abstract excerpt

The KCNJ2 gene mutations induce short QT syndrome (SQT3) by directly increasing the I K1 current. There have been many studies on the electrophysiological effects of mutations such as the KCNJ2 D172N that cause the SQT3. However, the KCNJ2 E299V mutation is distinguished from other representative gene mutations that can induce the short QT syndrome (SQT3) in that it increased I K1 current by impairing the inward...
