Generation of human iPSC line from an arrhythmogenic cardiomyopathy patient with a DSP protein-truncating variant

[摘要] Arrhythmogenic cardiomyopathy is an inheritable heart disease characterized by lethal heart rhythms and abnormal contractile function. Mutations in desmoplakin (DSP), a protein linking the cardiac desmosome with intermediate filaments, are associated with arrhythmogenic cardiomyopathy. Here we generated a human induced pluripotent stem cell (hiPSC) line from a patient with a heterozygous protein-truncating variant in DSP (c.1386del Leu462Serfs*22). This line has a normal karyotype and expression of pluripotency markers, and can differentiate into all three germ layers. This line is well suited for in vitro mechanistic studies of mechanism of DSP protein-truncation mutations in the context of arrhythmogenic cardiomyopathy.
