Human induced pluripotent stem cell line ZZUNEUi027-A generated from a long QT syndrome patient with a heterozygous KCNH2 (c. 128 A > G) mutant.

Long QT syndrome is one of the most common hereditary arrhythmias. Mutations in KCNH2 can cause long QT syndrome type 2 (LQT2). In this study, we generated a human induced pluripotent stem cell line ZZUNEUi027-A from a LQT2 female patient with c. 128A → G in KCNH2 gene using non-integrative Sendai viral reprogramming technology. This cell line expresses pluripotency markers, exhibits a normal female karyotype (46, XX) and could differentiate into all three germ layers in vitro. ZZUNEUi027-A can serve as a cell disease model in the understanding of LQT2 pathogenesis.
