NS1643 enhances the activity of T1019PfsX38 and Q1070X hERG channels associated with long QT syndrome type 2
Type 2 long QT syndrome (LQT2) increases the risk of cardiac arrest and sudden death due to reduced rapid delayed rectifier potassium currents (IKr) in the heart. Caused by loss-of-function genetic variants in the hERG K+ channel, LQT2 might benefit from variant-targeted therapy approaches. T1019PfsX38 and Q1070X are L...
