  • Title: Raised serum ferritin concentration in hereditary hyperferritinemia cataract syndrome is not a marker for iron overload.
    Author: Yin D, Kulhalli V, Walker AP.
    Journal: Hepatology; 2014 Mar; 59(3):1204-6. PubMed ID: 24003015.
    Abstract:
    Hyperferritinemia and bilateral cataracts are features of the rare hereditary hyperferritinemia cataract syndrome (HHCS; OMIM #600886). HHCS is an autosomal dominant condition caused by mutations which increase expression of the ferritin light polypeptide (FTL) gene. We report a patient with HHCS who was misdiagnosed and treated as having hemochromatosis, in whom a heterozygous c.-160A>G mutation was identified in the iron responsive element (IRE) of FTL, causing ferritin synthesis in the absence of iron overload. This report demonstrates the need for clinical awareness of HHCS as a cause of hyperferritinemia in the absence of iron overload and provides a possible diagnostic schema.
