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.

DNA Repair in Human Cancer-Prone Genetic Diseases
We are investigating the role of DNA repair in prevention of cancer and in human development. The approach involves integrated clinical, molecular, and translational investigations of disorders with defective DNA repair. Current studies are focusing on two rare genetic diseases: xeroderma pigmentosum (XP) a cancer-prone genetic disease with cellular hypersensitivity to ultraviolet radiation (UV) and defective DNA repair and trichothiodystrophy (TTD) a disorder with developmental abnormalities and defects in some of the same genes as XP without increased cancer risk.
The long-term goals are to: 1) define the molecular defects in these diseases, 2) characterize their clinical abnormalities and extent of phenotypic heterogeneity, 3) correlate the molecular defects with clinical abnormalities, 4) assess the altered molecular function, 5) identify and characterize the underlying mechanisms (pathophysiology) and how they lead to clinical disease, and 6) influence these processes by exploring methods of cancer prevention.
Collaborators on our research include Margaret Tucker, Human Genetics Program, Division of Cancer Epidemiology and Genetics, NCI; Brian Brooks, National Eye Institute (NEI); and Carmen Brewer, National Institute on Deafness and Other Communication Disorders (NIDCD).

Services for Children with Disabilities
Are Special Education Services Required in the Time of COVID-19? - Link to the American Bar Association statement on special education services and COVID-19. Contains suggestions for parents of special needs children who are experiencing disruption of services.
Responsibilities of local educational districts to children with special needs - This is a statement from the Federal Department of Education describing the responsibilities of local educational districts to children with special needs.
Center for Parent Information & Resources - Online center for parents who have children with disabilities. Provides information on COVID-19 and special education needs. We understand that social isolation, reduction in physical activity, unpredictability and changes in routine can all contribute to increasing stress. People living with DNA repair conditions often have some aspects of physical distancing. However, missing out on school activities, therapies or being required to attend school classes and work from home can feel isolating.
