Living with Oculootoradial syndrome

A very rare genetic condition with arm and hand differences, eye movement problems, and hearing loss from birth.

Understanding Oculootoradial syndrome

Oculootoradial syndrome, also called IVIC syndrome, is a very rare genetic condition affecting the arms, eye muscles, and hearing.

People have differences in the upper limbs, such as thumb and forearm bone differences and fused wrist bones. Eye movement problems and hearing loss that is present from birth and does not worsen 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:

  • Underdeveloped forearm bone (radius)
  • Short or unusually shaped thumb
  • Fused wrist bones or forearm bones
  • Crossed eyes (strabismus)
  • Hearing impairment
  • Short stature and scoliosis

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, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in SALL4 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
