The Urea Cycle Disorders Consortium's Administrative Unit coordinates all UCDC activities and is led by UCDC principal investigator/director, Mark L, Batshaw, MD. Co-principal investigators have spefic roles to ensure that the Consortium operates smoothly. Dr. Mendel Tuchman serves as Administrative Director and Co-PI, leading the the consortium when Dr, Batshaw is unable to do so, assisting Dr. Batshaw with Consortium administration and directing the clinical and pilot projects, Co-Pl Marshall Summar is responsible for industry and international relationships,assists Dr. Batshaw withUCDC administration and with Dr. Brendan Lee co-directs the training program: Co-Pl Cynthia LeMons is the executive director of the National Urea Cycle Disorders Foundation and serves as an advisor to the UCDC leadership, representing patients'interests in major UCDC decisions. She will also direct external communications from the UCDC to the patient community. Dr. Robert McCarter from Biostatistics and Study Design Unit at Children's Medical Center and Dr. Jeffrey Krischer from the Data Management and Coordinating Center at University of South Florida will advise the UCDC leadership on study design and results analysis. In addition to the directors. Dr. Brendan Lee at Baylor College of Medicine directs the training program, project manager Jennifer Seminara is responsible for UCDC operations, and Arlene Gendron assists with administrative duties. The UCDC holds monthly conference calls and one annual in-person meeting: The DMCCs audit program ensures quality data and is supplemented by a monitoring program directed by the UCDC project manager.
