Affected Participants
Subjects who have suppurative lung disease without a known genetic diagnosis
|
Diagnostic Test: Genetic Testing for PCD or PID
Patients with high likelihood of a PID disorder or a high likelihood of PCD will initially undergo research genetic testing on a commercial approved panel for PID disorders or a panel of at least 37 PCD genes. |
Unaffected Family Members
Unaffected family members may be enrolled in the study for collection of DNA only
|
Other: Unaffected Family Member Genetic Testing
Unaffected family members will undergo genetic testing if genetic findings are identified in their affected family member. |
- Number of Participants with a Confirmed Diagnosis of PCD or PID [ Time Frame: Up to approximately 4 years ]A commercial genetic panel will be used to test for disease causing mutation in PCD or PID. If the commercial panel does not yield positive results, WES research testing will be used to identify disease causing mutations in PCD and PID in order to confirm the diagnosis.
- Prevalence of Neonatal Respiratory Distress Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of neonatal respiratory distress (occurs at birth).
- Prevalence of the Onset of Chronic Nasal Congestion Before Six Months of Age Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of the onset of chronic nasal congestion before age 6 months.
- Prevalence of the Onset of Daily Wet Cough Before Six Months of Age Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of the onset of daily wet cough before age 6 months.
- Prevalence of Laterality Defects Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of laterality defects (situs inversus/heterotaxy).
- Prevalence of Chronic/Recurrent Sinus Disease Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of chronic/recurrent sinus disease.
- Prevalence of Chronic/Recurrent Middle Ear Disease Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote presence or absence of chronic/recurrent middle ear disease.
- Prevalence of Recurrent Pneumonia/Sepsis Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote to denote presence or absence of recurrent pneumonia/sepsis (that is not bronchiectasis).
- Prevalence of Skin Infections/Abscesses Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Medical records will be reviewed to denote to denote presence or absence of skin infections/abscesses.
- Prevalence of Abnormal Nasal Nitric Oxide Values Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Nasal nitric oxide will be measured to determine the number of subjects who have an abnormal value, utilizing a cut-off of 77 nl/min.
- Prevalence of Abnormal Immunoglobulin G Values Seen in PCD and PID [ Time Frame: During a single 6-hour visit ]Immunoglobulin G will be measured to determine the number of subjects who have an abnormal value, utilizing the local laboratory age-defined cut-off ranges (United States: mg/dL; Canada: g/L).
- Prevalence of Abnormal Lymphocyte Markers Seen in PCD and PID (Laboratory Tests) [ Time Frame: During a single 6-hour visit ]Lymphocyte Markers will be measured to determine the number of subjects who have an abnormal value, utilizing the local laboratory age-defined cut-off ranges (% of lymphocytes).
- Mean FEV1 Percent Predicted Values in PCD and PID [ Time Frame: During a single 6-hour visit ]Forced expired volume in 1 second (FEV1) will be assessed by percentage of the predicted value (0-100%).
