Establishment of a human-induced pluripotent stem cell line, KSCBi014-A, from a long QT syndrome type 2 patient harboring a KCNH2 mutation

초록

Long QT syndrome type 2 (LQT2) is a heart disorder caused by a loss-of-function mutation in the KCNH2 gene that is an essential factor in cardiac repolarization and affects the heart rate. This study has generated a human-induced stem cell line (KSCBi014-A) carrying the KCNH2 (c.453delC) mutation from an LQT2 patient. The non-integrative Sendai virus-mediated induced pluripotent stem cell (iPSC) reprogramming method was used for iPSC line generation. The KSCBi014-A line maintained stem cell-like morphology, normal karyotype, and pluripotency, and could differentiate into three germ layers in vitro.
