FTL gene


Gene (OMIM No.)
Function of gene/protein
  • Ferritin light chain
  • Involved in iron storage and detoxification
Clinical phenotype
(OMIM phenotype no.)
  • Autosomal dominant
Ocular features
  • Photosensitivity
  • Retinal degeneration
  • Cataracts
Visual function
  • Progressive vision loss
Systemic features
  • Movement disorders (e.g., chorea, dystonia)
  • Neurodegeneration
Key investigations
  • MRI: detection of brain iron accumulation
  • Genetic testing: identification of FTL mutations
  • Symptomatic treatment for movement disorders
  • Regular neurological and ophthalmological follow-up
