XPO1 and familial dilated cardiomyopathy: Furthermore, the two pathologies shared 6 altered genes: XPO1 (Exportin 1), ARL4 (ADP-ribosylation factor-like 4A), NFKB2 (Nuclear factor of kappa light polypeptide gene enhancer in B-cells 2), FHL3 (Four and a half LIM domains 3), RANBP2 (RAN binding protein 2), and RHOU (Ras homolog family member U) that showed an identical trend in expression in both ICM and DCM.
