Coexistent Alpha-1 Antitrypsin Deficiency and Hereditary Hemochromatosis.

Alpha-1 antitrypsin (AAT) deficiency and hereditary hemochromatosis are systemic diseases inherited in an autosomal recessive fashion. The primary manifestation of AAT is early-onset pulmonary disease, while hemochromatosis primarily affects function of the liver, heart, and pancreas through excess iron deposition. No clear association between the two diseases has been delineated.
