Generation and genetic repair of two human induced pluripotent cell lines from patients with Epidermolysis Bullosa simplex and dilated cardiomyopathy associated with a heterozygous mutation in the translation initiation codon of KLHL24
Summary
Fibroblasts from two patients carrying a heterozygous mutation in the translation initiation codon (c.2 T > G) of the kelch-like protein 24 (KLHL24) gene were used to generate human induced pluripotent stem cells (hiPSCs), using non-integrating Sendai virus to deliver reprogramming factors. CRISPR-Cas9 editing was used for genetic correction of the mutation in the patient-hiPSCs. The top-predicted off-target sites were not altered. Patient and isogenic hiPSCs showed typical morphology, expressed pluripotency-associated markers, had the capacity for in vitro differentiation into the three germ layers and displayed a normal karyotype. These isogenic pairs will enable in vitro modelling of KLHL24-associated heart and skin conditions. Copyright © 2021 The Author(s). Published by Elsevier B.V. All rights reserved.
