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. The gene discussed is ARL4A; the disease is familial dilated cardiomyopathy.
