Date not reportedResearchers intend on diagnosing and treating certain inborn errors of metabolism. By doing this researchers hope to expand their knowledge about these disorders and provide access to patients of interest for research, teaching, and clinical experience. Patients participating in this study will be examined and treated on an out patient basis, if practical. However, patients requiring specialized tests or treatments will be admitted to the NIH Clinical Center as necessary. Researchers will use only accepted medical procedures in diagnosing (medical history, physical examinations, X-ray studies, eye examinations, blood tests, and urine tests) and treating the patients involved in this study. Additional tests may be required on a case to case basis. Many patients seen in this study will go on to be enrolled in a specific disease-related research study.\<TAB\>...
