- hepatic hemosiderosis in hemochromatosis


- classical primary hemochromatosis (HFE1) (MIM.235200): HFE mutations at 6p21.3 (MIM.235200)

- juvenile hemochromatosis (HFE2s) (MIM.602390)

  • HFE2A: HJV mutations (hemojuvelin) (MIM.608274)
  • HFE2B: HAMP mutations (hepcidin antimicrobial peptide) (MIM.606464)

- hemochromatosis type 3 (HFE3) (MIM.604250) is an autosomal recessive disorder. It is caused by mutation in the gene encoding transferrin receptor-2 (TFR2) (MIM.604720), which maps to 7q22.

- hemochromatosis type 4 (HFE4) (MIM.606069) is an autosomal dominant disorder. It is caused by mutation in the SLC40A1 gene (MIM.604653), which encodes ferroportin and maps to 2q32.


- HFE1: HFE gene mutations
- HFE2A: HJV (hemojuvelin) (MIM.608274)
- HFE2B: HAMP mutations (MIM.606464)
- HFE3: transferrin receptor-2 (TFR2) (MIM.604720) at 7q22.
- HFE4: SLC40A1 gene (MIM.604653) encoding ferroportin at 2q32.
