Living with Xeroderma pigmentosum variant type

A milder form of xeroderma pigmentosum with sun-sensitive skin and a higher chance of skin cancer, often noticed in the teen or adult years.

Understanding Xeroderma pigmentosum variant type

Xeroderma pigmentosum variant type is a milder form of xeroderma pigmentosum (XP) with severe sun sensitivity and a higher risk of skin cancer.

It is a rare genetic condition of sun sensitivity. GARD lists onset in the teen and adult years. It affects the skin and eyes, including dry skin, freckles in sun-exposed areas, changes in skin color and eye sensitivity to light.

Signs & symptoms

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

  • Skin that burns easily in sunlight
  • Freckles in sun-exposed areas
  • Dry skin
  • Patchy darker or lighter skin
  • Extreme eye sensitivity to light
  • Skin cancers, including melanoma

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 cancer specialists, eye disease specialists, genetic specialists and skin, hair, and nail specialists.

  3. Consider genetic testing

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