Derivation and characterization of two human induced pluripotent stem cell lines (NUIGi004-A) and (NUIGi012-A) from two patients with LQT2 disease


Long QT syndrome type 2 (LQT2) is associated with KCNH2, which encodes the α subunit of the ion channel that controls the K+ current in the heart. Mutations of KCNH2 cause loss of Kv11.1 channel function by disrupting subunit folding, assembly, or trafficking of the channel to the cell surface. Here we generated two induced pluripotent stem cell (iPSC) lines from two patients carrying mutation in KCNH2 gene. These iPSCs express the pluripotent markers and have the capacity of differentiation into other cell types. These patient-derived iPSCs are useful for investigating the disease pathology and identifying the therapeutic target. Copyright © 2021 The Authors. Published by Elsevier B.V. All rights reserved.
