Living with Bohring-Opitz syndrome

A rare genetic condition that affects the development of many body parts, including learning, seizures, and the eyes.

Understanding Bohring-Opitz syndrome

Bohring-Opitz syndrome is a rare genetic condition that affects the development of many parts of the body.

Most people have profound to severe intellectual disability, developmental delay, and seizures. Some have a small head or a pointed forehead, and some have differences in brain structure. Eye problems that can affect vision are common. Features can start during pregnancy or in the newborn period.

Signs & symptoms

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

  • Severe intellectual disability
  • Seizures
  • Feeding difficulties in infancy
  • Low muscle tone
  • Small head (microcephaly)
  • Bulging eyes and other eye differences

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 bone and joint specialists, brain and nervous system specialists and genetic specialists.

  3. Consider genetic testing

    Changes in ASXL1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.

  4. Connect with expert centers

    ASXL Rare Research Endowment Foundation and World Craniofacial Foundation may keep lists of experts for this condition.
