Abstract
Congenital long QT syndrome type 2 (LQT2) results from KCNH2 mutations that cause loss of Kv11.1 channel function which can lead to arrhythmias, syncope, and sudden death. Here, we generated three human-induced pluripotent stem cell (iPSC) lines from peripheral blood mononuclear cells (PBMCs) of two LQT2 patients carrying pathogenic variants (c.1714G>A and c.2960del) and one LQT2 patient carrying a variant of uncertain significance (c.1870A>T) in KCNH2. All lines show typical iPSC morphology, high expression of pluripotent markers, normal karyotype, and differentiate into three germ layers in vitro. These lines are valuable resources for studying the pathological mechanisms of LQTS caused by caused by KCNH2 mutations.
