Laboratory evaluation revealed markedly elevated serum ferritin levels with normal transferrin saturation and no evidence of systemic iron overload.

The coexistence of FTL mutation and HFE H63D homozygosity appears to be incidental and should be interpreted cautiously. Recognition of this condition is essential to prevent unnecessary investigations and inappropriate treatment.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1155\/crpe\/7970734","type":"journal-article","created":{"date-parts":[[2026,7,14]],"date-time":"2026-07-14T08:21:34Z","timestamp":1784017294000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Hereditary Hyperferritinemia Cataract Syndrome Mimicking Iron Overload in a Pediatric Patient With Coexisting HFE H63D Homozygosity"],"prefix":"10.1155","volume":"2026","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0255-1266","authenticated-orcid":false,"given":"Ye\u015fim","family":"Yi\u011fit","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5218-7880","authenticated-orcid":false,"given":"Hamide Bet\u00fcl Gerik","family":"\u00c7elebi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,7,14]]},"reference":[{"key":"e_1_2_9_1_2","article-title":"Hereditary Hyperferritinemia Cataract Syndrome: A Case Report","volume":"10","author":"Neofytou A.","year":"2025","journal-title":"Journal of Pediatric Hematology\/Oncology"},{"key":"e_1_2_9_2_2","article-title":"Hereditary Hyperferritinemia Cataract Syndrome: Physiopathology and New Cases","volume":"22","author":"Nos F.
