PKP2 and arrhythmogenic right ventricular cardiomyopathy: Khudiakov et al. (56) obtained an iPSC line carrying 2 mutations in the PKP2 gene from a 14-year-old female with severe ARVC, and detected high OCT4, NANOG, and SOX2 mRNA levels after reprogramming and transducing them with Sendai virus vectors, confirming the pluripotency of the iPSC line.
