Diagnostic Evaluation of Patients With Neuromuscular Diseases

The objectives of this protocol are to: 1) screen patients with various neuromuscular disorders and facilitate their entry into appropriate research protocols; 2) help resolve puzzling diagnostic neuromuscular problems and train fellows in the evaluation and treatment of Neuromuscular Diseases; and 3) provide follow up to patients who finished their participation in a previous study but they are not currently entered in another research protocol. No investigational treatments will be performed on this protocol but the tissues collected can be used for future research studies.
