ABSTRACT
We describe a new Italian family with 7 members affected by hereditary hyperferritinemia cataract syndrome (HHCS), an uncommon autosomal dominant disease caused by mutations of the iron-responsive element (IRE) of the ferritin light chain (FTL) gene determining its overexpression. The family diagnosis of HHCS took place after finding high ferritin levels in a 6-year-old girl. Seven members of the family had bilateral and symmetrical cataracts, normal iron, and hematological parameters except for high serum ferritin levels. About 160 families/unrelated cases with HHCS are known worldwide. This report documents a second Italian family, with a c.-168G>C mutation that is located in the highly conserved 3-nucleotide bulge structure of the FTL in the 5' untranslated region. This case shows how important the family history is in reaching a correct diagnosis and avoiding unnecessary and invasive analysis. HHCS should be considered in the differential diagnosis of childhood hyperferritinemia, especially in the presence of normal transferrin saturation.
