Do you or your child have primary ciliary dyskinesia (PCD) or primary immune deficiency (PID)? This study aims to identify genes that cause these two conditions, which can have similar symptoms. The results from this study will help researchers find new ways to treat breathing and hearing problems caused by these two conditions in a cross-sectional cohort of patients with PCD and PID. Participants in this study must be 5 to 45 years old. This study is taking place at multiple locations in the United States and in Canada.

Do you or your child have symptoms of a serious lung disease but no diagnosis? This study aims to develop new ways to diagnose primary ciliary dyskinesia (PCD) and 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 ant tell the difference between these two conditions. Participants in this study must be 5 to 45 years old. This study is taking place at multiple locations in the United States and in Canada.

Are you a woman who is postmenopausal or a man older than 65? This study will investigate the effects of oral progesterone for older women and testosterone for older men on QT intervals. QT intervals that are increased by medicine can lead to dangerous heart rhythm problems. Researchers hope to learn more about why this happens and how to deliver safer doses. This study is located in Indianapolis, Indiana.
