Abstract

Ultraviolet (UV)-induced DNA lesions are almost exclusively removed by the nucleotide excision repair (NER) pathway, which is essential for prevention of skin cancer development. Patients with xeroderma pigmentosum (XP) are extremely sun sensitive due to a genetic defect in components of the NER cascade. They present with first signs of premature skin aging at an early age, with a considerably increased risk of developing UV-induced skin cancer. XP belongs to the group of DNA repair defective disorders that are mainly diagnosed in the clinic and in hindsight confirmed at the molecular level. Unfortunately, there are no causative treatment options for this rare, autosomal-recessive disorder, emphasizing the importance of an early diagnosis. Subsequently, UV-protective measures such as the reduction of exposure to environmental UV and regular skin cancer screenings should be undertaken to substantially improve prognosis as well as the disease course.
