This edited iPS cell line (rs199473662 (KCNQ1 c.568C>T; p.Arg190Trp) is a causal variant for Long QT Syndrome Type 1 (LQT1). It can be differentiated into iPSC-derived cardiovascular cells (iPSC-CVPC) for studying LQT1 syndrome, used in drug screens (including in drug induced LQT), and in gene therapy. Additional clone (UCSD242i-LQT1-1) is available from WiCell.
