Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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\>
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
We propose to characterize the etiology and natural history of rare inborn errors of metabolism and other genetic disorders, both known and yet-to-be discovered. In so doing, we will expand our knowledge about these disorders and provide access to patients of interest for research, teaching, and clinical experience.
Objectives:
The overall aim of this protocol is to advance our knowledge of genetic disorders.

Eligibility Criteria
Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.
Inclusion Criteria
Examples of disorders that will be under this protocol include inherited developmental defects or diatheses toward infections, cancer, or an environmentally induced disease. The principal investigator, along with consulting specialists, will review the medical records of prospective participants and offer admission based upon the potential to help the individual, to learn from the participant, or to initiate clinical or basic research suggested by the participant s workup. This protocol is not intended to serve as an umbrella protocol for small studies of specific disorders. In general, no more than 5 families known to have the same disorder will be investigated under this protocol.
Some participants will be relatives of patients with known diagnoses, and their specimens will be obtained for the purpose of heterozygote testing or to serve as controls to help diagnose the proband. All participants shall be seen as inpatients, outpatients or via Telehealth at the discretion of the principal investigator, based upon particular research interests and expertise. Normal adult volunteers aged 18 years or older will be enrolled to provide control blood and urine specimens.
Exclusion Criteria
* Participants over two years of age will not be admitted if they are medically unstable and do not require admission to the Clinical Center for diagnosis.
* Pregnant women are excluded.
