Dilated cardiomyopathy 1Z

Dilated cardiomyopathy-1Z (CMD1Z) is characterized by severe reduction in cardiac function, with onset in infancy or early childhood in some patients but diagnosis as late as the fifth decade in others. Patients exhibit biventricular systolic dysfunction, with severely reduced left ventricular ejection fractions. Most affected individuals require transplantation for survival (Mogensen et al., 2004; Kaski et al., 2007; Pinto et al., 2011). For a general phenotypic description and a discussion of genetic heterogeneity of dilated cardiomyopathy, see CMD1A (115200). [from OMIM]
