Living with Giant axonal neuropathy

An inherited condition of the nerves that begins in early childhood with walking problems and slowly gets worse.

Understanding Giant axonal neuropathy

Giant axonal neuropathy is an inherited condition with abnormally large, poorly working nerve fibers called giant axons.

Symptoms start in the peripheral nerves, which connect the brain and spinal cord to muscles and sensory cells, and the central nervous system is affected too. Signs usually begin in early childhood and get worse over time. Most people first have trouble walking. Some people have a milder form that begins later in life.

Signs & symptoms

Symptoms vary from person to person. GARD describes these:

  • Trouble walking
  • Loss of feeling, strength, and reflexes in the limbs
  • Poor coordination (ataxia)
  • Curved spine (scoliosis)
  • Very kinky hair
  • Constipation, heat intolerance, and reduced sweating

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

    Your doctor may refer you to a specialist who knows rare conditions.

  3. Ask which tests can help

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