Long QT syndrome is one of the most common hereditary arrhythmias in clinic. Mutations in AKAP9 gene can lead to long QT syndrome type 11 (LQT11). In this study, a human induced pluripotent stem cell line ZZUSAHi004-A from a 3-year-old male patient with long QT syndrome carrying a heterozygous mutation in AKAP9 gene using non-integrative Sendai viral reprogramming technology. ZZUSAHi004-A showed normal male karyotype (46, XY), expressed pluripotency markers and could differentiate into all three germ layers in vitro. ZZUSAHi004-A can serve as a cell disease model in the understanding of LQT11 pathogenesis.
