Screening Protocol to Evaluate Patients for Approved Studies

This protocol is designed to screen patients with either diagnosed or undiagnosed conditions, and provides for determining eligibility for approved protocols within the Gene Therapy and Therapeutics Branch (GTTB), National Institute of Dental and Craniofacial Research. The purpose of the protocol is to allow evaluation of patients who do not meet the requirements for other screening protocols, such as the screening protocol for Sjogren's syndrome patients. Each subject will be evaluated to determine whether they are suitable candidates for inclusion in any protocols in the GTTB. The screening evaluation will include past and current medical history, and an appropriate physical examination. Further routine diagnostic tests may also be performed to determine eligibility for approved studies. The tests and procedures are of minimal risk. When the screening has been completed, subjects will be informed of the options available at the time for participation in available, approved research protocols.
