Event Type:  Grand Rounds (This is an NIH Science event)
Title:  When the Lifeguard for the Gene Pool Goes on Strike: DNA Repair Disorders Xeroderma Pigmentosum and Trichothiodystrophy
Description:  DNA repair plays a major role in protecting the genome by removing DNA damage caused by sun exposure. Xeroderma pigmentosum (XP) patients with defective DNA nucleotide excision repair (NER) have a 10,000 fold increase in sunlight induced cancers of the skin (basal cell carcinoma, squamous cell carcinoma, and melanoma) and eyes. Some XP patients also have progressive neurological degeneration. Trichothiodystrophy (TTD) patients have defects in some of the same NER genes as XP patients, but their phenotype is remarkably different. Children with TTD have developmental abnormalities including congenital cataracts, absent myelin in the brain, short stature, developmental delay, multiple infections, and bone abnormalities without increased cancer. This puzzling multisystem disorder can be diagnosed by examination of their short brittle hair with a polarizing microscope revealing “tiger tail” banding of the hair shafts.
