Living with 2q24 microdeletion syndrome

A chromosome condition that can bring seizures, eye differences, delayed development, and autism.

Understanding 2q24 microdeletion syndrome

2q24 microdeletion syndrome is a chromosome condition caused by a partial deletion of the long arm of chromosome 2.

Features depend on which region is deleted. They can include seizures, a smaller head, cleft palate, and eye differences such as coloboma, cataract, and small eyes. Slow growth, heart defects, limb differences, developmental delay, and autism can also occur. GARD lists onset as during pregnancy and as a newborn.

Signs & symptoms

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

  • Global developmental delay
  • Intellectual disability
  • Cleft palate
  • Clouding of the eye lens (cataract)
  • Small eyeball (microphthalmia)
  • Autistic behavior

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 brain and nervous system specialists and genetic specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    Dystonia Medical Research Foundation may keep lists of experts for this condition.
