Living with Ataxia-photosensitivity-short stature syndrome

A rare genetic syndrome with balance problems, sun sensitivity, short stature, and intellectual disability.

Understanding Ataxia-photosensitivity-short stature syndrome

Ataxia-photosensitivity-short stature syndrome is a rare genetic syndrome with balance problems, sensitivity to sunlight, short height, and intellectual disability.

The ataxia looks like a problem in the cerebellum, the part of the brain that coordinates movement. Sun sensitivity mainly affects the face and trunk. Other features can include a curved pinkie finger, a single crease across the palm, a high palate, enlarged calves, and heart valve differences. It begins in infancy and childhood. GARD notes there have been no further descriptions in the medical literature since 1983.

Signs & symptoms

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

  • Poor balance and coordination (ataxia)
  • Sensitivity to sunlight (photosensitivity)
  • Short stature
  • Intellectual disability
  • Crossed eyes (strabismus)
  • Dry skin and hives

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 and genetic specialists.

  3. Ask which tests can help

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

  4. Connect with expert centers

    National Ataxia Foundation may keep lists of experts for this condition.
