Abstract

Long QT syndrome (LQTS), an inherited cardiac ion channelopathy, is associated with ventricular arrhythmias and risk of sudden death. LQTS sub-type 2 (LQT2) is caused by pathogenic variants in KCNH2 encoding the α-subunit of Kv11.1, thus affecting the rapid component of delayed rectifier K+ current (IKr) channel during the action potential. In this study, non-integrational Sendai reprogramming method was used to generate an induced-pluripotent-stem-cell (iPSC) line carrying the KCNH2 c.2464G>A (p.Val822Met) pathogenic variant from a LQT2 patient. This patient-specific iPSC line NUIGi003-A harbouring the c.2464G>A variant expressed pluripotency markers and demonstrated the differentiation potential to all three germ layers.
