Living with COFS syndrome

A condition that mainly affects the brain, eyes, and spinal cord and is usually found at birth, with low muscle tone and distinct facial features.

Understanding COFS syndrome

Cerebro-oculo-facio-skeletal (COFS) syndrome is a degenerative disorder that mainly involves the brain, eyes, and spinal cord.

People have mild to severe intellectual disability, very low muscle tone, weak reflexes, vision problems, and involuntary eye movements. Children have distinct facial features, including low-set ears, small eyes, a small head, and a small jaw. Skull, limb, heart, and kidney differences can occur. It is often diagnosed at birth. GARD says the cause is often unknown.

Signs & symptoms

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

  • Small head size (microcephaly)
  • Very low muscle tone (hypotonia)
  • Cataracts and small eyes
  • Calcium deposits in the brain
  • Joint contractures present from birth
  • Small or underdeveloped cerebellum

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, cancer specialists, ear, nose, and throat specialists and eye disease specialists.

  3. Ask which tests can help

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