Genetic Factors Influencing Lung Disease Development Including Cystic Fibrosis, Asthma, and Pulmonary Fibrosis An Observational Study with Optional CT Scan Sub-study

What this Trial Is About

Researchers are evaluating genetic factors involved in the development of various lung diseases such as alpha 1-antitrypsin deficiency, asthma, chronic obstructive pulmonary disease, cystic fibrosis, sarcoidosis, and others. The study aims to understand how genetic variations affect respiratory function by comparing gene expression in lung cells from patients and healthy individuals. The research focuses on identifying the distribution of specific gene variants related to lung disease among affected patients and age- and sex-matched healthy volunteers. Participants include those with lung diseases or possible pulmonary conditions and healthy controls. An optional CT sub-study is offered to some adults and children aged 9 and older with cystic fibrosis, comparing standard CT scans with low dose radiation CT scans to evaluate an alternative method for monitoring lung abnormalities. This may involve one additional low dose CT scan during participants next annual imaging. During the study, participants undergo genetic testing and assessments related to lung function, including chest x-rays and pulmonary function tests. Some participants may take part in the CT scan sub-study with additional imaging. Researchers will monitor hereditary factors over one year and continue assessing CT scan techniques. Participation includes evaluations of lung disease symptoms, imaging, and gene analysis, aiming to improve understanding of lung disease development over time.
