In rare circumstances, however, ferritin levels may be primarily elevated due to a genetic cause. We report a case of a three-year-old male patient with incidentally detected hyperferritinemia who was found to harbor the c.-168G>T mutation in the FTL gene, confirming hereditary hyperferritinemia-cataract syndrome (HHCS). This evidence concerns the gene FTL and hereditary hyperferritinemia with congenital cataracts.
