Ferroportin Q248H and low iron stores are both associated with lower circulating tumor necrosis factor-alpha, while only ferroportin Q248H is associated with lower circulating macrophage migration inhibitory factor. Whether the reduced production of tumor necrosis factor-alpha observed in ferroportin Q248H heterozygotes may be of significance in anemia of chronic disease is yet to be determined.
