Do you have symptoms of a lung disease (such as long-term wet cough, bronchiectasis, or recurrent pneumonia) with no genetic diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) or primary immune deficiency (PID), two conditions that can have similar symptoms. Researchers will combine information from genetic testing, lung imaging, and lung function tests to diagnose and tell the difference between these two conditions. Participants in this study must be 5 to 45 years old and must have symptoms of a serious lung disease but no diagnosis. This study is taking place at multiple locations in the United States and in Canada, including the NIH Clinical Center in Bethesda, Maryland.
