Ciliary motility disorders are conditions that affect the movement of cilia, which are tiny hair-like structures on the surface of cells. Cilia play a crucial role in various bodily functions, including clearing mucus from the respiratory tract and aiding in the movement of eggs in the female reproductive system. When cilia do not function properly, it can lead to respiratory issues, fertility problems, and other health complications. These disorders can be caused by genetic mutations, infections, or environmental factors. Common examples include Primary Ciliary Dyskinesia (PCD), where cilia are immotile or move abnormally, leading to chronic respiratory infections and other symptoms. Diagnosis often involves imaging studies and genetic testing to identify the underlying cause.
