Mutation spectrum in Australian pedigrees with hereditary hyperferritinaemia-cataract syndrome reveals novel and de novo mutations.
Hereditary hyperferritinaemia-cataract syndrome (HHCS) (OMIM #600886) is a rare autosomal dominant condition identified by high serum ferritin levels with normal iron saturation and distinctive bilateral cataract. It may be misdiagnosed as haemochromatosis and such patients become anaemic as a result of inappropriate venesection. The elevated serum ferritin is due to a mutation in the iron-responsive element (IRE) of the l-ferritin gene, resulting in excessive l-ferritin production. We report the identification of three Australian pedigrees; one with a previously described mutation at position 40, a pedigree with a novel mutation at position 39 and an individual with a de novo mutation at position 32 of the l-ferritin IRE.
