Hemochromatosis is an autosomal recessive syndrome that occurs in patients who carry two pathogenic or likely-pathogenic (P/LP) variants in HFE. HFE is included on some genetic testing panels used for patients with AF. Hemochromatosis causes cardiomyopathy due to iron overload in the ventricle; however, it is unknown whether AF can be an early manifestation that is identified by genetic te...
