| Summary: | CTNNA3, first reported in association with arrhythmogenic right ventricular cardiomyopathy in 2003, is an unique component of both desmosomes and adherens junctions. Using Sendaivirus-mediated reprogramming, we generated an induced pluripotent stem cell (iPSC) line from the peripheral blood mononuclear cells of a child with arrhythmia. The iPSCs exhibited stable amplification, expressed pluripotent markers, and differentiated spontaneously into three germ layers in vitro. Additionally, this iPSC line was found to maintain a normal karyotype and retain the pathogenic mutation in CTNNA3, facilitating a platform to study the disease mechanisms of arrhythmia and dysfunctions related to CTNNA3 mutations.
