Generation of a CRISPR/Cas9-edited Plakoglobin (JUP) knock-out (JMUi001-A-4) iPSC line to model the cardiac phenotype of arrhythmogenic cardiomyopathy.

Arrhythmogenic cardiomyopathy (ACM) represents the cardiac phenotype of Naxos disease, an autosomal recessive disease with an additional cutaneous phenotype. ACM is mainly caused by mutated desmosomal proteins, which are part of cardiac adherens junctions and provide mechanical and electrical stability. Here, we generated a knock-out (KO) of the junctional protein Plakoglobin (JUP-KO; JMUi001-A-4) using the CRISPR/Cas9 system in healthy control induced pluripotent stem cells (iPSCs, (JMUi001-A). JUP-KO iPSCs maintained pluripotency, differentiation potential and genomic integrity and provide an in vitro system modelling ACM when differentiated into cardiomyocytes.
