Urea Cycle Disorders (UCDs) are a group of rare, monogenic disorders that affect the ability of the urea cycle pathway to clear ammonia from the body and to maintain an efficient redox metabolism in the mitochondria. Ammonia is a toxic byproduct of protein metabolism, and alterations in the urea cycle can lead to its accumulation in the blood, resulting in hyperammonemia. Additionally, UCDs can lead to metabolic disturbances that cause lifelong complications. Our research aims at improving diagnosis and developing new therapeutic approaches for UCDs. Key areas of investigation include:
Urea Cycle Disorders Translational Center aims to change the landscape of research by translating innovative therapies from the laboratory bench to the clinic, focusing on providing new treatments perspectives that could help, give hope and improve the quality of life of patients suffering from any of the urea cycle disorders. The center has been stablished through the collaboration of the University of Zürich & Citrin Foundation, under the auspices of the UZH Foundation and hosted at the Children’s Research Center of the University Children’s Hospital Zurich.
The main goal of this study is to identify circulating biomarkers that are specific to Citrin Deficiency using both targeted and untargeted metabolomics, proteomics, lipidomics, and transcriptomics analysis of collected blood samples.

We are using CRISPR-based approaches, such as prime editing, to correct genetic mutations that cause Citrin Deficiency in liver cells. These studies pave the way for clinical trials that can lead to a cure for Citrin Deficiency.
It is unclear how nutrients are processed to produce energy in patients with Citrin Deficiency. Using stable isotope tracers in vivo, we are able to track how nutrients are metabolized in patients and how their liver metabolic functions are altered.
It is important to be able to measure the severity of Citrin Deficiency. For this purpose we are defining scoring systems that cover physical health and also Patient Reported Outcome Measures (PROMs). Patients’ perspectives are vital for providing patient-centered healthcare and interventions.
