We are investigating the role of DNA repair in prevention of cancer and in human development. We perform clinical, molecular, and translational investigations of two rare genetic disorders with defective DNA repair: xeroderma pigmentosum (XP) with clinical and cellular hypersensitivity to ultraviolet radiation and a 10,000-fold increased risk of skin cancer and trichothiodystrophy, a disorder with developmental abnormalities and defects in some of the same genes as XP without increased cancer risk. We recently found that the molecular changes in skin melanomas from the XP patients were closely related to sun exposure and different from the general population.
