PY - 2019 T2 - Fitzpatrick's Dermatology, 9e AB - AT-A-GLANCEGenome instability characterizes a large group of inherited disorders with prominent cutaneous abnormalities; many have an increased cancer risk.Genome instability is caused by impaired repair and/or maintenance of DNA.Xeroderma pigmentosum is a prototype with impaired repair of environmentally induced DNA damage and a greatly increased frequency of sunlight-induced cancer.Although these disorders are rare, heterozygous carriers of affected genes, which may comprise several percent of the general population, may carry an increased cancer risk as well.
