Establishment of a human induced pluripotent stem cell line, KSCBi015-A, from a long QT syndrome type 1 patient harboring a KCNQ1 mutation

초록

Long QT syndrome type 1 (LQT1) is a genetic cardiac disorder caused by a loss-of-function mutation in the KCNQ1 gene. In this study, we generated a human induced stem cell line (KSCBi015-A) from an LQT1 patient with a heterozygous mutation located in the KCNQ1 gene, c.569G > A. The KSCBi015-A cell line showed the maintenance of stem cell-like morphology, normal karyotype, and pluripotency, and could differentiate into three germ layers in vitro.
