Please read more information about your appointment at our clinic. Xeroderma pigmentosum (XP) is one of more than 10 different disorders that are characterized by skin that is damaged by ultraviolet light because of defective nucleotide excision repair or NER. You can come to this clinic with your family or a friend until you feel confident to come on your own. You and your family can meet both the adult and children's XP teams together in 1 clinic.

Background The frequency of cancer, neurologic degeneration and mortality in xeroderma pigmentosum.neurological signs (14 to 40% of patients): mental retardation, pyramidal syndrome, peripheral neuropathia more severe central nervous system (CNS) disorders are observed when mutations occur in XPA DNA binding site Xeroderma pigmentosum (XP) is a rare autosomal recessive disorder characterized by marked sun sensitivity, defective DNA repair, and a > 1000fold increased frequency of skin cancers at an early age.
photophobia, often the first sign, before cutaneous lesions followed by bilateral cataract increased risk of ocular benign and malign tumors.Although the specific cellular defect is as yet unknown, recent studies seem to indicate an enzymatic deficiency.
