Jan 30, 2015 CLINICAL TRIAL FOR ASA/ASL TREATMENT OPEN FOR ENROLLMENT: The long awaited clinical trial "Nitric Oxide Supplementation as a Therapeutic Intervention in Argininosuccinic Aciduria (ASA)" is now open for enrollment at Baylor College of Medicine (one of the UCD Research Consortium clinical research sites) in Houston, Texas. A result of their pioneering discovery on the role of the urea cycle in regulating nitric oxide in the human body, the study is being conducted by Dr. Sandesh Nagamani and Dr. Brendan Lee to determine if supplementation of nitric oxide (NO) will lessen or correct the effects of NO deficiency in the arteries of individuals with ASA deficiency. The goal of the study is to better understand the role of NO deficiency in ASA and whether supplementation with NO is an effective treatment for ASA. DETAILS AND ELIGIBILITY

June 10, 2014 NUCDF 2014 FELLOWSHIP GRANT AWARDED TO LINDSAY BURRAGE, MD, PhD
The purpose of the NUCDF's Fellowship Grant is to improve the quality of care for urea cycle disorder-affected individuals by attracting promising new clinicians and researchers with interest in biochemical genetics to the field of urea cycle disorders. The NUCDF Fellowship helps support postdoctoral fellows specialize and focus on research, clinical treatment and coordination of multidisciplinary care of UCDs, while advancing the understanding and treatment of our disorders.
Our 2014 Fellowship has been awarded to Dr. Lindsay Burrage of Baylor College of Medicine. Dr. Burrage will be working under the direction of preeminent UCD scientist and clinician, Dr. Brendan Lee. Dr. Burrage is an outstanding candidate who will be conducting research studies to investigate whether a form of the arginase enzyme could be used to reduce blood arginine levels in an animal model of Arginemia. If her animal studies prove supportive, a clinical trial for enzyme replacement for arginase deficiency may be developed. Previous NUCDF Fellowship awardees include Oleg Shchelockov, MD (2009), Ayelet Arez, MD PhD (2008) and Sandesh Nagamani MD(2011), resulting in transformational research on the role of nitric oxide in ASA and an upcoming clinical trial for a new treatment for ASA.

UPDATE: NUCDF FELLOWSHIP RESEARCH TEAM LED BY BRENDAN LEE, MD, PhD LEADS TO TRANSFORMATIONAL SCIENTIFIC DISCOVERY
NUCDF is proud to announce that the work of Dr. Lee and three NUCDF Fellows has resulted in a major discovery in ASA deficiency that transforms human science. The research has been published in Nature Medicine, a preeminent scientific journal, and challenges long-held theories about the role of nitric oxide in the human body as a regulator of cardiovascular health. The discovery is the result of research spanning several years conducted by three consecutive NUCDF Fellowship awardees, Ayelet Erez, MD, PhD, Oleg Shchelochkov, MD, and Sandesh Nagamani, MD. Dr. Stephen Cederbaum says of Dr. Lee's work, "He has transformed treatment of this rare condition and illustrates what one creative mind in the hands of an excellent and persistent scientist can do." NUCDF and our families are delighted beyond words that our investment in these three promising young scientists and Dr. Lee's work has resulted in this life-changing discovery.
"These findings open a door into ways to explore the effect of nitric oxide on a host of disorders. We hope it transforms the field,” said Dr. Lee in a recent press release. A renowned UCD expert, beloved champion of UCD families, and member of NUCDF's Medical Advisory board for over a decade, Dr. Lee has received the prestigious NIH Director's Award for Transformative Research.
UPDATE ON ARGININE THERAPY FOR ARGININOSUCCINIC ACIDURIA AND ITS EFFECTS ON LIVER DYSFUNCTION:

HELP MOVE RESEARCH FORWARD FOR NEWBORN SCREEN FOR OTC AND CPS1 DEFICIENCIES: A study to validate a newborn screen for OTC deficiency, CPS1, and potentially NAGS is being conducted to help identify infants affected with the disorders at birth. The pilot study has been successful in identifying cases, but more samples are needed to fully validate the screen. If your child is affected with OTC, CPS1 or NAGS, please consider releasing their newborn screening card to this research study. Most states store the NBS cards for several months; many store indefinitely and these samples can be accessed with your consent. Newborn screening is already available in most states for ASA lyase, citrullinemia and arginase deficiency, making it possible to identify and treat affected children early, resulting in significantly improved outcomes. Imagine the lives that would be saved and the neurological disabilities that could be avoided if all newborns were screened at birth for all the urea cycle disorders. Your help can make the difference!
UPDATE: NUCDF has formed a Task Force of experts in UCD to prepare the application required for submission to the Health and Human Services Secretary's Advisory Committee on Heritable Disorders in Newborns to request the addition of OTC deficiency to the HHS recommended newborn screening panel. After a ten-year struggle to find a way to screen newborns for OTC, we have light at the end of the tunnel. The above study is ongoing for OTC, CPS1 and NAGS screens, so please consider participating.
For more study details and consent forms, please contact Cindy Le Mons, NUCDF Executive Director at OTC/CPS/NAGS Screen Study
