Living with Hereditary hyperferritinemia with congenital cataracts

An inherited condition with high ferritin in the blood and clouding of the eye lenses from infancy.

Understanding Hereditary hyperferritinemia with congenital cataracts

Hereditary hyperferritinemia with congenital cataracts is an inherited condition with extra ferritin, an iron storage protein, in the blood and tissues.

The ferritin buildup starts early in life and leads to cataracts, usually in infancy rather than after age 60. Cataracts that are not removed cause vision to get dimmer and blurrier. The high ferritin does not usually cause other health problems, but it can be mistaken for liver disorders. People with this condition do not have extra iron, so repeated blood draws can lead to anemia.

Signs & symptoms

Symptoms vary from person to person. GARD lists these among the most common:

  • Clouding of the eye lens (cataract)
  • High ferritin level on blood tests

Not everyone has every symptom. GARD's list comes from the Human Phenotype Ontology.

Diagnosis

  1. Talk with your doctor

    Share the symptoms you've noticed, when they started and your family health history. Notes and photos can help.

  2. See a specialist

    Specialists who may be involved include eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in FTL are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  • Connect with rare disease patient organizations for support
  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
Bring these questions to your next doctor visit
Could genetic testing for the FTL gene confirm the diagnosis?
How can we avoid unneeded tests or treatments for high ferritin?
How often should the eyes be checked for cataracts?

Quick facts

Symptoms usually startany time in life
InheritanceAutosomal Dominant
GenesFTL

It is caused by changes in the FTL gene. It is autosomal dominant, so one changed copy of the gene is enough.
