Citrin deficiency
MONDO:0016602Citrin deficiency is a rare autosomal recessive urea cycle defect characterized clinically by recurring episodes of hyperammonemia and associated neuropsychiatric symptoms in the adult-onset form (citrullinemia type II), and by transient cholestasis and variable hepatic dysfunction in the neonatal form (neonatal intrahepatic cholestasis due to citrin deficiency).

One-Time gene fix could free kids from lifelong diet and meds
Disease control Recruiting nowThis early-phase trial tests a single intravenous dose of a gene editing therapy called LNP.UCD.ABE in 7 children with severe urea cycle disorders. The therapy aims to correct the genetic defect using a lipid nanoparticle to deliver a base editor. The main goal is to check safety…

New hope for kids with rare metabolic disease: 5-Year trial launches
Disease control Recruiting nowThis study is testing a drug called glycerol phenylbutyrate in 40 Chinese children with urea cycle disorders, a rare genetic condition that causes dangerous ammonia buildup. The drug aims to help control ammonia levels over 5 years. Researchers will monitor safety and effectivene…

Simple test could unlock better monitoring for rare metabolic disorders
Diagnosis Recruiting nowThis study is testing a new way to measure how well the urea cycle works in healthy people and in patients with urea cycle disorders (UCDs). Participants receive a safe, non-radioactive tracer, and blood samples are taken over a few hours. The goal is to develop a better tool for…

Brain scans reveal how urea cycle disorder affects driving ability
Knowledge-focused Recruiting nowThis study uses a brain imaging technique called functional near-infrared spectroscopy (fNIRS) to observe brain activity in people with urea cycle disorder (UCD) while they perform driving tasks of varying difficulty. Researchers compare these brain patterns to those of healthy v…
