INTRODUCTION: Hereditary Hyperferritinemia-Cataract Syndrome (HHCS, MIM #600886) is a rare autosomal dominant genetic disorder characterized by elevated serum ferritin levels and early-onset cataracts. This condition is caused by mutations in the iron-responsive element (IRE) within the 5' untranslated region (UTR) of the ferritin light chain ( CASE PRESENTATION: In this study, we performed sequence analysis of the ferritin L-chain ( CONCLUSION: Genetic factors, while rare, are a significant cause of hyperferritinemia. In cases where hyperferritinemia is accompanied by early-onset cataracts, genetic etiologies should be considered. Multidisciplinary evaluation of patients can help avoid unnecessary treatments and improve quality of life through timely interventions.
