January 31, 2020 UCD MOM PUBLISHES CHLDREN'S STORY: Based on her son's experiences with UCD, the illustrated book weaves a magical story of whimsical adventures in hopes of raising awareness of rare diseases and learning to live with a rare condition.
October 24, 2019 UREA CYCLE DISORDERS RESEARCH CONSORTIUM RECEIVES NEW 5-YEAR FUNDING:National Institutes of Health Rare Diseases Clinical Research Network has awarded the Urea Cycle Disorders Consortium (UCDC) $5 million funding to continue research for urea cycle disorders. Founded in 2003 by UCD clinical research experts and the National Urea Cycle Disorders Foundation (NUCDF), the UCDC was established and received its first 5-year funding as one of ten consortia to study rare diseases by the Office of Rare Disease Research.
Now co-led by principal investigators Dr. Andrea Gropman at Children's National Medical Center, Dr. Sandesh Nagamani at Baylor, and Cynthia Le Mons at NUCDF, the17-site international UCD Consortium of physicians, scientists, neuropsychologists, nurses, genetic counselors and researchers will continue to work in collaboration with UCD patients and families to conduct studies to improve the understanding of UCDs, long-term health outcomes, and accelerate the development of new treatments.
"It's gratifying that patients diagnosed with urea cycle disorder now are surviving, growing up, becoming young adults and starting families themselves. Twenty to 30 years ago, this never would have seemed conceivable," Dr. Gropman says. "We have collected many years of longitudinal clinical data, but with this new funding we can address critical questions about UCD that are meaningful on a day-to-day basis for UCD patients and families and improve long-term health and quality of life."

UCD International Patient-Reported Outcome Study:Report your own unique experiences as a parent or individual affected by UCD. Help increase the understanding of UCD, how many people have the disorder, and how diagnosis, treatment and outcomes can be improved. You can help identify under-recognized issues and areas that need more research. Details
1) Studies using MRI techniques are being conducted to investigate the effects of UCD on brain function. Details HERE. For more information or how to participate contact NUCDF.
2)Study of past MRIs: If your child (or an affected adult) has had an MRI or EEG in the past, sign a consent to release the data to Dr. Andrea Gropman at Children's National Medical Center for reinterpretation by new software in a special study of effects of UCD on brain function.
