- Background: Congenital dyserythropoietic anemia type III (CDA III) can be caused by mutation in KIF23. CDA III differs from CDA I and II in the sense that secondary hemochromatosis has not been reported. However, we have observed elevated serum ferritin in a CDA III family. Since primary hemochromatosis is common in Northern Europe we decided to screen the family for HFE mutations. Aim: Study clinical appearance and prevalence of HFE gene mutations, C282Y and H63D, in a CDA III family. Methods: DNA from 37 CDA III patients and 21 non-affected siblings was genotyped. Iron status from EDTA plasma was measured in 32 of the CDA III patients and 18 of the non-affected siblings. Results: Out of 37 CDA III patients, 18 carried heterozygous HFE mutations and six were compound heterozygotes. Out of 21 CDA III negative siblings, nine had heterozygous HFE mutations, two were homozygous (one H63D and one C282Y), and two were compound heterozygous. None of the patients with wt HFE , regardless of CDA III status, suffered from iron overload. Four patients with HFE mutations needed treatment with phlebotomy to normalize ferritin and transferrin iron saturation; one CDA III negative patient with homozygous C282Y, two CDA III patients with heterozygous HFE mutations and one CDA III case with compound heterozygosity. Conclusion: HFE mutations were found in 65 % of CDA III patients and in 62 % of their CDA III negative siblings. Heterozygous HFE mutation, C282Y and even H63D, can cause iron overload when occurring concomitantly with CDA III.
