Specific Disorders:

Arginase 1 Deficiency (ARG1D)

Argininosuccinate Synthase Deficiency (Citrullinemia I)

Argininosuccinate Lyase (ASL) Deficiency (Argininosuccinic Aciduria)

Carbamyl Phosphate Synthetase Deficiency (CPSD)

N-Acetylglutamate Synthase (NAGS) Deficiency

Ornithine Transcarbamylase (OTC) Deficiency


Past Studies (no longer accruing)

For All Urea Cycle Disorders Studied by the UCDC:

Argininosuccinate Lyase Deficiency (Argininosuccinic Aciduria)

Ornithine Transcarbamylase (OTC) Deficiency

Argininosuccinate Synthetase Deficiency (ASSD) (Citrullinemia I)

 

Please Note: The Rare Diseases Clinical Research Network will make every effort to enroll all the patients we can, but we cannot make any guarantees that we will be able to enroll everyone in a particular study who wants to participate.

 

Other urea cycle disorders research conducted outside of the UCDC

ClinicalTrials.gov, a service of the U.S. National Institues of Health, is a registry and results database of publicly and privately supported clinical studies of human participants conducted around the world.  Patients and families can use the website to search for clinical studies for a particular disorder or in a particular geographic region.  It can also be used to learn more about clinical studies.  Researchers use the site to register studies and to share results.  To find other clinical studies, type "urea cycle disorders" and/or your specific disorder (e.g. OTC, ornithine transcarbamylase deficiency, arginanse deficiency, etc.) in the "Search for Studies" field.
