Living with UV-sensitive syndrome

An inherited condition that makes skin very sensitive to sunlight, so even a little sun can cause sunburn.

Understanding UV-sensitive syndrome

UV-sensitive syndrome is a condition marked by sensitivity to the ultraviolet (UV) rays in sunlight.

Even a small amount of sun can cause sunburn. After repeated sun exposure, people may get freckles, dry skin, or color changes on sun-exposed skin. Some have small clusters of enlarged blood vessels (telangiectasia) on the cheeks and nose. GARD says their risk of skin cancer is not higher than in the general population.

Signs & symptoms

Symptoms vary from person to person. GARD describes these:

  • Sunburn after a little sun
  • Freckles on sun-exposed skin
  • Dry skin
  • Changes in skin color
  • Small clusters of blood vessels on the cheeks and nose

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 genetic specialists and skin, hair, and nail specialists.

  3. Ask which tests can help

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

  • Keep notes on symptoms, changes and questions for appointments
  • Ask about patient registries that help research
  • Look into financial aid and travel resources for care visits
