correspondence Haptoglobin polymorphism and serum ferritin concentration in ageing subjects.

The article reports on haptoglobin polymorphism and serum ferritin concentration in ageing subjects. In randomly selected control subjects, in blood donors homozygous for the HFE C282Y mutation, and in first-time blood donors lacking the HFE mutations, it was found that their was no influence of Hp type on transferrin saturation and serum ferritin concentration. It was found that the influence of Hp type on serum iron status was exclusively present in males aged 18-50 years. The influence of Hp 2-2 type on serum ferritin concentrations cannot be observed in subjects aged >50 years.
