Xeroderma pigmentosum (XP) is a rare genetic disorder that affects the skin’s ability to repair DNA damage caused by ultraviolet (UV) light. This condition is characterized by an increased sensitivity to UV radiation, leading to an increased risk of skin cancers and other skin problems.
Symptoms
Common symptoms of XP include:
- Increased sensitivity to UV radiation, leading to sunburn and blistering
- Premature aging of the skin, including wrinkles and age spots
- Increased risk of skin cancers, including melanoma and non-melanoma skin cancers
- Eye problems, including cataracts and conjunctivitis
- Neurological problems, including seizures and developmental delays
Causes
XP is caused by a mutation in one of several genes that are responsible for repairing DNA damage caused by UV radiation. This mutation can be inherited from one’s parents or can occur spontaneously.
Types of XP:
- Classic XP: This is the most common form of XP and is characterized by an increased sensitivity to UV radiation and an increased risk of skin cancers.
- Variant XP: This form of XP is characterized by a milder sensitivity to UV radiation and a lower risk of skin cancers.
- Xeroderma pigmentosum-Cockayne syndrome: This is a rare form of XP that is characterized by an increased sensitivity to UV radiation and an increased risk of skin cancers, as well as neurological problems.
Diagnosis
Diagnosing XP typically involves a physical exam, medical history, and laboratory tests, such as:
- Skin biopsy: A skin biopsy can be used to examine the skin for signs of XP.
- Genetic testing: Genetic testing can be used to identify the mutation that is causing XP.
- UV radiation testing: This test can be used to measure the skin’s sensitivity to UV radiation.
Treatment Options
Treatment for XP typically involves avoiding UV radiation and using protective measures, such as:
- Sunscreen: Using a broad-spectrum sunscreen with a high SPF can help protect the skin from UV radiation.
- Clothing: Wearing protective clothing, such as long-sleeved shirts and pants, can help protect the skin from UV radiation.
- Eye protection: Wearing sunglasses that provide UV protection can help protect the eyes from UV radiation.
- Avoiding UV radiation: Avoiding UV radiation from sources such as tanning beds and welding equipment can help reduce the risk of skin cancers.
