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. DESCRIPTION (provided by applicant): The overall goal of this application is to establish a Rare Disease Clinical Research Center (RDCRC) at the University of North Carolina (UNC), and an associated Network of geographically-dispersed Airways Research Centers (ARCs), to study rare diseases of the airways. These 4 sites (UNC; Washington Univ., St. Louis; Univ. of Colorado, Denver; and Univ. of Washington, Seattle) will collaborate in diagnostic, genetic, and other studies in patients with genetic impairments in mucociliary clearance, specifically primary ciliary dyskinesia (PCD), variant forms of cystic fibrosis (CF), and pseudohypoaldosteronism (PHA). Patients with these unusual disorders with increased morbidity and mortality often have delayed (or incorrect) diagnoses, because diagnostic tests are not readily available. The two central hypotheses of this application are that: 1) a broad-based, systematic approach to the diagnostic evaluation of these patients will yield more precise diagnostic criteria and better diagnostic techniques, including genetic testing; and 2) systematic evaluation of specific cohorts of these patients with state-of-the-art methodologies and rigorous cross-sectional and longitudinal study designs will provide better understanding of the clinical pathogenesis of these disorders. In a five-year longitudinal study of 300 patients with PCD, we will use innovative techniques, including measurement of PFTs and HRCTs of the chest in infants, to define early onset and progression of pulmonary disease in PCD. In addition, 10 geographically-dispersed sites will serve as PCD Clinical Centers, to assist in the follow-up care of PCD patients in the longitudinal study. This collaborative effort will improve care by defining clinical practice guidelines for PCD. Our Pilot projects in PCD are designed to develop better diagnostic tools and biomarkers, characterize the respiratory pathobiology, evaluate novel therapeutic agents, and develop screening tests for PCD. We will extend our training programs in rare airways diseases to established and young investigators at UNC, and to investigators at other sites. Finally, we will work with the DTCC to coordinate and expand current websites to provide information to the lay public, patients, and medical professionals for education, referral, and recruitment of study subject

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。 描述（由申请人提供）：本申请的总体目标是在北卡罗来纳州大学（University of North Carolina，简称北卡罗莱纳）建立一个罕见病临床研究中心（RDCRC），以及一个地理上分散的气道研究中心（ARC）的相关网络，以研究气道的罕见病。这4个研究中心（美国;华盛顿大学，圣路易斯;科罗拉多大学，丹佛;和华盛顿大学，西雅图）将在诊断，遗传学和其他研究中合作，在患者的遗传损伤，粘膜纤毛清除，特别是原发性纤毛运动障碍（PCD），变异形式的囊性纤维化（CF），和假性醛固酮减少症（PHA）。这些不寻常的疾病患者的发病率和死亡率增加，往往延误（或不正确）的诊断，因为诊断测试是不容易获得。本申请的两个中心假设是：1）对这些患者进行诊断评估的基础广泛的系统方法将产生更精确的诊断标准和更好的诊断技术，包括基因检测;和2）用最先进的方法和严格的交叉研究对这些患者的特定队列进行系统评价，分段和纵向研究设计将提供对这些疾病的临床发病机制的更好理解。在对300例PCD患者进行的为期5年的纵向研究中，我们将使用创新技术，包括测量婴儿胸部的PFT和HRCT，以确定PCD中肺部疾病的早期发作和进展。此外，10个地理位置分散的研究中心将作为PCD临床中心，以协助纵向研究中PCD患者的随访护理。这种合作努力将通过定义PCD的临床实践指南来改善护理。我们的PCD试点项目旨在开发更好的诊断工具和生物标志物，表征呼吸道病理生物学，评估新型治疗药物，并开发PCD的筛选试验。我们将把我们在罕见气道疾病方面的培训计划扩展到在芝加哥大学的成熟和年轻的研究人员，以及其他研究中心的研究人员。最后，我们将与DTCC合作，协调和扩展现有网站，为非专业公众、患者和医疗专业人员提供教育、转诊和招募研究受试者的信息
