LONGITUDINAL STUDY OF UREA CYCLE DISORDERS

这个子项目是许多研究子项目中的一个 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得了主要资金， 因此可以在其他CRISP条目中表示。所列机构为 研究中心，而研究中心不一定是研究者所在的机构。 本研究的目的是对尿素循环障碍（UCD）患者的自然史、发病率和死亡率进行纵向多学科调查。受试者总数为200例。每年将招募约30名参与者。年龄范围从1天到99岁。研究持续时间为20年。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. The purpose of this study is to conduct a longitudinal multidisciplinary investigation of the natural history, morbidity, and mortality in people with Urea Cycle Disorders (UCD). The total number of subjects will be 200. Approximately 30 participants will be enrolled per year. Age can range from 1day to 99 years. The duration of the study will be 20 years.
