XPO1, a nucleocytoplasmic transport-related genes, had a potent relationship with left ventricular function parameters and could distinguish differentiation at the transcriptome level between dilated cardiomyopathy and ischemic cardiomyopathy and provide a basis for the therapeutic selection.[28] In ischemic cardiomyopathy patients, XPO1 was high expressed and inversely correlated with left ventricular function. The gene discussed is XPO1; the disease is dilated cardiomyopathy.
