Living with Cataract 6 multiple types

An eye condition with cloudy lenses, caused by changes in the EPHA2 gene, that can come with nearsightedness.

Understanding Cataract 6 multiple types

Cataract 6 is a cataract (clouding of the eye's lens) caused by a change in the EPHA2 gene.

It can include several types of cataract. GARD lists cataract at the back of the lens (posterior polar cataract) and cloudy lenses present at birth among its signs. Some people are also nearsighted or have changes at the back of the eye.

Signs & symptoms

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

  • Cataract at the back of the lens (posterior polar)
  • Cloudy lens present at birth (developmental cataract)
  • Nearsightedness (myopia)
  • Thinning at the back of the eye (chorioretinal atrophy)

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 change in the EPHA2 gene causes this condition. It is inherited in an autosomal dominant way, so one changed copy of the gene can cause it.
