(Press-News.org) The National Urea Cycle Disorders Foundation (NUCDF), the leading patient advocacy group for people affected by urea cycle disorders (UCDs), today announced the launch of a two-year national project to establish the multistakeholder NUCDF Partner Network and develop a roadmap for future research in these rare disorders. The project is funded through the Eugene Washington PCORI Engagement Award Program, an initiative of the Patient-Centered Outcomes Research Institute (PCORI).
Urea cycle disorders (UCDs) are eight related genetic disorders of protein metabolism that can lead to high ammonia resulting in coma, brain damage, and death.
Decades ago, a UCD diagnosis often meant fatal outcomes in infancy. If patients survived, they likely faced damage and high levels of illness. Today, thanks to years of research advances, UCDs have been transformed into complex but chronic illnesses for many patients, allowing them to achieve improved health outcomes and survive into adulthood.
Emerging gene therapies—such as the recent, promising individualized CRISPR gene editing treatment of a baby with a severe UCD called CPS1 deficiency—are both raising hope among UCD patients and complicating the UCD treatment landscape. Patients must choose between medical management, liver transplant, joining trials, or waiting for these potential new therapies to become broadly available.
“The UCD community now finds itself at a critical research juncture,” says Tresa Warner, NUCDF’s executive director. “While medical advances have led to multiple treatments, patients and clinicians have insufficient data to guide health care decisions. Patients are living longer than ever before and facing new challenges. We want to empower the broad UCD community to work together effectively to identify and prioritize patient needs in UCD research, consider emerging treatments, and build a sustainable infrastructure for multi-stakeholder engagement that continues beyond this project.”
Representatives of the UCD community will be invited to join the NUCDF Partner Network, which will include patients and caregivers, clinician-researchers, front-line providers, metabolic dietitians, and industry representatives. Network members will be trained in patient-centered research, help identify research needs, and work together to create a research roadmap.
NUCDF’s Warner, a UCD parent who has been a patient advocate for more than 25 years, will lead the project along with NUCDF deputy director Jill Willliams, a science writer, project manager and UCD family member. Anna Wexler, PhD, a UCD parent and bioethics researcher at the University of Pennsylvania, will guide the project’s qualitative research components.
Researchers with the Urea Cycle Disorders Consortium (UCDC) are among those who will join the project. NUCDF is the sole patient advocacy partner for this expert research network, which was funded since 2003 under the National Institutes of Health’s Rare Diseases Clinical Research Network.
This project, Building Capacity for Patient-Centered Comparative Effectiveness Research on Urea Cycle Disorders, is part of a portfolio of projects funded by PCORI to help develop a community of patients, caregivers, clinicians and other stakeholders who are better equipped to engage as partners in all phases of patient-centered comparative clinical effectiveness research (CER) and to disseminate results of PCORI-funded studies. Through its Engagement Award Program, PCORI is creating an expansive network of individuals, communities and organizations who can leverage their lived experience and expertise to influence research to be more patient-centered, relevant and useful.
PCORI is a nonprofit organization with a mission to fund research that will provide patients, their caregivers, and clinicians with the evidence-based information that is needed to make better-informed health care decisions.

About Urea Cycle Disorders (UCDs)
Urea cycle disorders are eight related disorders caused by genetic mutations that lead to deficiencies in enzymes or transporters crucial to removing ammonia, a toxic byproduct of protein metabolism, from the bloodstream. The specific mutation and degree of enzymatic function determine the onset and severity of UCDs. They are estimated to affect approximately 1 in 35,000 people. Ornithine transcarbamylase (OTC) deficiency is the most common type of UCD. Others include arginase deficiency, argininosuccinate lyase deficiency (ASL, also known as argininosuccinic aciduria or ASA), carbamoyl phosphate synthetase 1 (CPS1) deficiency, citrullinemia (also known as arginosuccinate synthase 1 deficiency or ASS1), and N-acetylglutamate synthase (NAGS). Additionally, there are secondary UCDs such as citrin deficiency and hyperammonemia-hyperornithinemia-homocitrullinuria (HHH) syndrome, also known as ornithine translocase deficiency.
About the National Urea Cycle Disorders Foundation (NUCDF)
NUCDF is a nonprofit organization dedicated to saving and improving the lives of children and adults affected by urea cycle disorders (UCDs) and raising awareness since 1988. Led exclusively by patients and families affected by UCDs, we are the driving force behind critical research to improve the understanding and management of UCDs, find new treatments, and ultimately create a cure. NUCDF serves as a lifeline to patients, families, and medical professionals worldwide seeking information, support, and hope. Visit www.nucdf.org or email info@nucdf.org.

HonorHealth Research Institute is helping give brain stroke victims a chance at improved recoveries thanks to data-driven medical care
2025-06-18
SCOTTSDALE, Ariz. — June 18, 2025 — More patients are surviving and recovering from the most common and severe form of brain stroke thanks to data-driven treatment methods based on the amassing of more than 1 million variables in an HonorHealth Research Institute program known as HALO, which stands for HonorHealth Acute neuroLogical Outcome.
Ischemic stroke, as opposed to bleeding caused by blunt force trauma, occurs when a blood vessel supplying oxygen to the brain is obstructed because of a blood clot — typically formed in the heart or an artery in the neck. Such blockages, responsible for 87% of all strokes, often result in permanent disability ...

Ear wax as a possible screening medium for Parkinson’s disease
2025-06-18
Most treatments for Parkinson’s disease (PD) only slow disease progression. Early intervention for the neurological disease that worsens over time is therefore critical to optimize care, but that requires early diagnosis. Current tests, like clinical rating scales and neural imaging, can be subjective and costly. Now, researchers in ACS’ Analytical Chemistry report the initial development of a system that inexpensively screens for PD from the odors in a person’s ear wax.
Previous research has ...
Credit scores of corporate executives may reveal their decisions
2025-06-18
COLUMBUS, Ohio – The personal credit scores of top-level corporate executives can help explain their decision making in the corporate environment, at least when it involves evaluating risk, a new study suggests.
Researchers at The Ohio State University conducted an experiment with a national sample of high-level executives and found that those with subprime credit scores tended to be “yes persons” – even when it was counterproductive.
In contrast, executives with prime ...
Neuroscientist explores ways to reduce seizures in children
2025-06-18
Humans have tens of thousands of genes, many of which produce proteins essential to basic bodily functions. The KCNT1 gene, for example, codes for a protein that maintains normal electrical activity in the brain and helps neurons communicate.
But genes don’t always function perfectly.
For many people, a mutation of the KCNT1 gene causes no symptoms. For others, it can lead to dysfunction of neuronal activity causing learning disabilities, difficulty communicating, and a lifetime of treatment-resistant seizures.
Epileptic disorders caused by mutations in KCNT1 affect ...
