On the other hand‚ too much iron is detrimental and can cause various significant diseases. C282Y and H63D are mutations found on the HFE gene and are the major cause of inherited iron overload (hereditary hemochromatosis). As a result‚ iron regulation is disrupted and too much iron is absorbed from a strong
