Diagnostic and Clinical Characterization of Patients With Unusual Genetic Disorders of the Airways

What this Trial Is About

This research focuses on primary ciliary dyskinesia (PCD), a genetic disorder that impairs the function of respiratory cilia, leading to lung disease. The study aims to identify key genes involved in normal ciliary function and understand how genetic mutations cause PCD and contribute to other common airway diseases like asthma and chronic obstructive pulmonary disease. The project seeks to improve diagnosis and insight into the genetic variability affecting ciliary function. The study is observational and involves identifying genetic mutations in patients with PCD, including those with unusual ciliary structures or functions. Researchers analyze the ultrastructure, wave form, and beat frequency of cilia to correlate genetic mutations with ciliary abnormalities. They study patients with typical and atypical PCD presentations, including those with normal ciliary ultrastructure but abnormal function, using family-based and proteomic approaches. Participants include people diagnosed with PCD or healthy volunteers with a family member diagnosed with PCD. The study involves detailed clinical characterization and genetic analysis but does not involve any treatment interventions. Researchers aim to understand the relationship between mutations and ciliary function, which may help diagnose PCD better and explore its role in other airway diseases. This study is ongoing, with participation involving genetic and clinical evaluations over time.
