A Mouse Model of Cardiomyopathy Induced by Mutations in the Hemochromatosis HFE Gene.

Background: The heart is 1 of the organs most affected by hereditary hemochromatosis (HH). The clinical impact of cardiomyopathy in patients with HH requires a particular diagnosis and less invasive treatments. We developed a model of cardiomyopathy in knockout (KO) mice for the high-Fe (HFE) gene and assessed left ventricular (LV) function and structure from 7-20 months.
