Living with Cataract 4 multiple types

An eye disease that can cause several different types of cataract, caused by a problem in the CRYGD gene.

Understanding Cataract 4 multiple types

Cataract 4 is a disease of the eyes that can cause many different types of cataracts (clouding of the eye's lens).

GARD lists several types, including crystalline, frosted, needle-shaped, lamellar, and punctate cataracts. People in the same family may have different types. Some people also have smaller than normal corneas (microcornea).

Signs & symptoms

GARD doesn't list specific symptoms for this condition yet. Its summary describes these features:

  • Cloudy lens of the eye (cataract)
  • Different cataract types, even within one family
  • Smaller than normal corneas (microcornea) in some people

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

    Your care team will decide which exams and tests can confirm the diagnosis.

Quick facts

InheritanceAutosomal Dominant

A problem in the CRYGD gene causes this condition. It is passed through families in an autosomal dominant way, so one changed copy of the gene can cause it.

Also known as: cataract (disease) caused by mutation in crygd; cataract 4 multiple types with or without microcornea; cataract 4 with microcornea; cataract 4, aculeiform; cataract 4, central nuclear; cataract 4, crystalline
