Natural History and Genetic Studies of Usher Syndrome Clinical Protocol support contract designed to attain extramural support for developing, designing, interpreting, and evaluating clinical trials, epidemiologic and natural history studies. In addition, it will provide for outcomes research involving eye diseases and visual disorders and some preclinical studies. The focus shall be on the design of studies and the collection, analysis, and interpretation of data emanating from these studies, as well as support, and monitoring patient safety and follow-up. Contractor shall also provide analytical and data management support, as described in the work statement, for specified clinical research data bases, cost-effectiveness and economic analyses, quality of life assessment and outcomes research. This will include, but not be limited to, the following areas: analysis of Medicare and other health care databases;evaluation of existing NEI databases such as, centralized NEI Intramural Research database, the Eye Disease Case Control Study, Early Treatment Diabetic Retinopathy Study, Framingham Eye Study, and intramural AIDS and uveitis databases. Objective of Clinical Protocol: This study will explore clinical and genetic aspects of Usher syndrome, an inherited disease causing deafness or impaired hearing, visual problems, and, in some cases, unsteadiness or balance problems. Patients with type 1 Usher syndrome usually are deaf from birth and have speech and balance problems. Patients with type 2 disease generally are hearing impaired but have no balance problems. Patients with type 3 disease have progressive hearing loss and balance problems. All patients develop retinitis pigmentosa, an eye disease that causes poor night vision and eventually, blindness.
