Furthermore, some metabolic pathologies that could explain the symptoms and biological abnormalities were ruled out: serum ceruloplasmin, copper levels, urinary copper excretion, serum iron and ferritin, alpha-1 antitrypsin—all within normal limits—excluding hemochromatosis, alpha 1 antitrypsin deficiency, and Wilson’s disease. The gene discussed is SERPINA1; the disease is hemochromatosis.
