Xeroderma pigmentosum (XP) service

We're the only dedicated national service in the UK for xeroderma pigmentosum (XP). 

XP is a rare, genetic condition. The body is unable to repair damage to the DNA in the skin, caused by ultraviolent radiation (UVR) present during daylight. 

People with XP are more likely to:

  • sunburn easily
  • develop abnormal freckles
  • develop eye problems due to damage from UVR
  • develop skin cancers

XP can also cause problems with the nerves or brain.

You'll be cared for by a range of health professionals with expertise in different areas. They'll work together to give you the best care. 

At our 'one stop' clinics, you'll see a variety of specialists. We can carry out biopsies and tests on the same day.

We also work with your local services to provide support between visits.

Our specialist nurses can visit you at your home, school or workplace to provide support and advice.

We also provide a service to help people move from our children's XP service to our adult service.

Our team includes:

  • consultants
  • clinical nurse specialists
  • an XP imaging practitioner
  • administration staff
