Zusammenfassung
Xeroderma pigmentosum ist eine seltene autosomal-rezessiv vererbte Genodermatose, die durch Mutationen in Genen, verantwortlich für die Reparatur UV-induzierter DNA-Schäden, verursacht wird. Die Erkrankung ist charakterisiert durch erhöhte UV-Lichtsensitivität und eine Poikilodermie, Augenbeteiligung und bei manchen Patienten durch ausgeprägte Sonnenbrände und neurologische Mitbeteiligung. Es besteht ein erhöhtes Risiko für die Entwicklung von Augen- und Hauttumoren an sonnenexponierten Arealen. Derzeit besteht keine kurative Therapie. Als protektive Maßnahme wird ein absoluter Lichtschutz vor allen UV-Strahlungen dringend empfohlen.
Abstract
Xeroderma pigmentosum is a rare autosomal recessive disorder which is caused by germinal mutations responsible for the repair of ultraviolet (UV) radiation-induced DNA lesions. It is characterized by hypersensitivity to UV radiation, poikiloderma, ocular surface disease, and in some patients pronounced sunburn and neurological disease. Patients have a very high risk of developing ocular and skin cancer on exposed body sites. No cure is available for these patients except complete protection from all types of UV radiation.
