We also observe dephosphorylation and nuclear translocation of the nuclear factor of activated T cells (NFAT), with concordant RAC-α-serine/threonine protein kinase (Akt) phosphorylation but no change to extracellular signal‐regulated kinase activation in chronically paced cardiomyocytes expressing DCM mutations. The gene discussed is AKT1; the disease is familial dilated cardiomyopathy.
