Xeroderma pigmentosum (XP) is a rare autosomal-inherited, skin and neurodegenerative disease in which exposure to sunlight can result in a high incidence of skin and mucous membrane cancer. XP is classified into eight genetic complementation groups by the present. In this inside, 7 groups from the XP-A group to the G group show the abnormality in nucleotide excision repair (NER). The symptoms of XP begin in early life. Severe sunburn and blistering occurs in a half of patients, and all show early extensive freckling. Cancer incidence for individuals with XP under 20 years of age is 2,000 times as high as incidence in the general population. Neurodegeneration can be correlated with mutations in specific XP genes (XPA, ERCC3, ERCC2 and ERCC5).
