Abstract
The differential diagnosis for hyperferritinemia is wide, including malignancy, infections, autoimmune disorders, hemophagocytic lymphohistiocytosis, hyperthyroidism, chronic kidney disease, and, most commonly, iron overload. As an acute-phase reactant, ferritin is usually elevated due to secondary causes. 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 case is distinguished by a unique four-generation family history of early-onset cataracts and elevated ferritin levels, underscoring the hereditary and novel nature of this disorder.
