Cilia are finger-like projections from cells that act as a cellular "antenna" to detect and respond to chemical or mechanical cues. One important cue is fluid flow during the process of establishing asymmetry during early embryogenesis, the formation of the kidney nephron, and the formation of other tubular structures such as the neural tube. A group of comparatively common inherited conditions called "ciliopathies" can arise when the structure or function of cilia are defective. For example, cystic kidney disease is a common feature of many ciliopathies, often leads to kidney failure, and is therefore a significant cause of childhood disease and death. The most severe ciliopathy ("Meckel-Gruber syndrome") also involves problems in the development of the brain and spinal cord (called "neural tube defects") that arise during growth of babies in the womb. Reduced or absent mucus clearance from the lungs is the main consequence in other ciliopathies ("primary ciliary dyskinesia"), which causes recurrent respiratory infections and progressive damage to the respiratory system. In many ciliopathies, there are disturbances in the patterns of left-right organization of the lungs and heart, which are also seen in congenital heart defects (CHD), the most common birth defect.This research proposes to identify many of the remaining disease genes that are defective ("mutated") in this group of ciliopathies. To achieve this aim, we will take advantage of recent exciting advances in genetic technology that allow us to analyze the entire coding parts of a patient's genome ("whole exome sequencing"). We are uniquely placed to do this work and have a proven track record of success in this field: we have formed excellent research partnerships with families and their clinicians in the local community to participate in gene identification studies, and we have the appropriate state-of-the-art technology, computer analysis tools and experience.The identification of a new ciliopathy gene provides two major benefits. Firstly, accurate genetic testing then becomes possible for patients and families, with improvements in diagnosis and genetic counselling. Secondly, important and often unexpected scientific insights are made into the disease mechanism of the ciliopathy and into the normal function of the disease gene, which can lead to new treatments. We also expect new insights into the causes of other, more common conditions such as polycystic kidney disease, spina bifida and congenital heart defects.

纤毛是细胞的手指状突起，充当细胞“天线”来检测化学或机械信号并做出反应。一个重要的线索是在早期胚胎发生、肾单位的形成以及其他管状结构（例如神经管）的形成过程中建立不对称性的过程中的液体流动。当纤毛的结构或功能有缺陷时，就会出现一组相对常见的遗传性疾病，称为“纤毛病”。例如，囊性肾病是许多纤毛病的共同特征，常常导致肾衰竭，因此是儿童疾病和死亡的重要原因。最严重的纤毛病（“梅克尔-格鲁伯综合征”）还涉及婴儿在子宫内生长过程中出现的大脑和脊髓发育问题（称为“神经管缺陷”）。肺部粘液清除减少或缺失是其他纤毛病（“原发性纤毛运动障碍”）的主要后果，导致反复呼吸道感染和呼吸系统进行性损伤。在许多纤毛病中，肺和心脏的左右组织模式出现紊乱，这在最常见的出生缺陷先天性心脏缺陷 (CHD) 中也可见到。这项研究旨在鉴定许多剩余的疾病基因在这组纤毛病中存在缺陷（“突变”）。为了实现这一目标，我们将利用遗传技术的最新进展，使我们能够分析患者基因组的整个编码部分（“全外显子组测序”）。我们在开展这项工作方面拥有得天独厚的优势，并在该领域拥有良好的成功记录：我们与当地社区的家庭及其临床医生建立了出色的研究合作伙伴关系，参与基因鉴定研究，并且我们拥有适当的状态-最先进的技术、计算机分析工具和经验。新纤毛病基因的鉴定有两大好处。首先，随着诊断和遗传咨询的改进，患者和家庭可以进行准确的基因检测。其次，对纤毛病的疾病机制和疾病基因的正常功能产生重要且常常出乎意料的科学见解，这可以带来新的治疗方法。我们还期望对其他更常见疾病（如多囊肾病、脊柱裂和先天性心脏缺陷）的病因有新的见解。
