Living with CODAS syndrome

A rare syndrome with brain, eye, tooth, ear, and bone differences.

Understanding CODAS syndrome

CODAS syndrome is a multiple congenital anomalies syndrome with Cerebral, Ocular, Dental, Auricular (ear), and Skeletal differences.

GARD lists onset in the newborn period and infancy. It can include cataracts, tooth enamel differences, spine and hip bone differences, and crumpled ears.

Signs & symptoms

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

  • Cataracts
  • Differences in tooth shape and enamel
  • Differences in spine bones
  • Differences in the hip bones
  • Crumpled ears
  • Differences at the ends of long bones

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, eye disease specialists and genetic specialists.

  3. Consider genetic testing

    Changes in LONP1 are linked to this condition. Genetic testing and counseling can help confirm a diagnosis and explain what it means for your family.
