Brief Summary
The investigators will utilize a systematic approach for the diagnostic evaluation of patients to identify characteristics which may distinguish between Primary Immunodeficiency (PID) disorders versus Primary Ciliary Dyskinesia (PCD).

Outcome Measures
Primary Outcomes (13)
Number of Participants with a Confirmed Diagnosis of PCD or PID
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.
Up to approximately 4 years
Prevalence of Neonatal Respiratory Distress Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of neonatal respiratory distress (occurs at birth).
During a single 6-hour visit
Prevalence of the Onset of Chronic Nasal Congestion Before Six Months of Age Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of the onset of chronic nasal congestion before age 6 months.
During a single 6-hour visit
Prevalence of the Onset of Daily Wet Cough Before Six Months of Age Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of the onset of daily wet cough before age 6 months.
During a single 6-hour visit
Prevalence of Laterality Defects Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of laterality defects (situs inversus/heterotaxy).
During a single 6-hour visit
Prevalence of Chronic/Recurrent Sinus Disease Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of chronic/recurrent sinus disease.
During a single 6-hour visit
Prevalence of Chronic/Recurrent Middle Ear Disease Seen in PCD and PID
Medical records will be reviewed to denote presence or absence of chronic/recurrent middle ear disease.
During a single 6-hour visit
Prevalence of Recurrent Pneumonia/Sepsis Seen in PCD and PID
Medical records will be reviewed to denote to denote presence or absence of recurrent pneumonia/sepsis (that is not bronchiectasis).
During a single 6-hour visit
Prevalence of Skin Infections/Abscesses Seen in PCD and PID
Medical records will be reviewed to denote to denote presence or absence of skin infections/abscesses.
During a single 6-hour visit
Prevalence of Abnormal Nasal Nitric Oxide Values Seen in PCD and PID
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.
During a single 6-hour visit
Prevalence of Abnormal Immunoglobulin G Values Seen in PCD and PID
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).
During a single 6-hour visit
Prevalence of Abnormal Lymphocyte Markers Seen in PCD and PID (Laboratory Tests)
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).
During a single 6-hour visit
Mean FEV1 Percent Predicted Values in PCD and PID
Forced expired volume in 1 second (FEV1) will be assessed by percentage of the predicted value (0-100%).
During a single 6-hour visit
Study Arms (2)
Affected Participants
Subjects who have suppurative lung disease without a known genetic diagnosis
Unaffected Family Members
Unaffected family members may be enrolled in the study for collection of DNA only
Interventions
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 will undergo genetic testing if genetic findings are identified in their affected family member.
Eligibility Criteria
Subjects who have suppurative lung disease but without a defined genetic diagnosis.
You may qualify if:
- General Criteria
- Age 5-45 years
- Male and Female Subjects
- All races and ethnicities
- Major Clinical Criteria
- \- Bronchiectasis in \> 1 lobe
- Minor Clinical Criteria, Lung
- Neonatal respiratory distress (in term neonates with O2 requirement)
- Chronic wet cough (year-round for at least 12 months)
- Recurrent episodes of bacterial bronchitis
- Recurrent pneumonia (confirmed on chest x-ray)
- Respiratory non-tuberculous mycobacteria (NTM) (documented respiratory NTM culture)
- Minor Clinical Criteria, Other
- Chronic nasal congestion
- Recurrent/chronic paranasal sinusitis
- +4 more criteria
You may not qualify if:
- Anyone who has a confirmed genetic diagnosis of PCD or PID
- Cystic Fibrosis
- Alpha-antitrypsin deficiency in adults (18 years and older)
- Congenital upper or lower airway anomalies
- Post-lung or heart transplant, or other conditions requiring immunosuppression therapy
- Other confounding features, such as lung disease due to prematurity (born \< 28 weeks gestation) or HIV
- Neurological compromise and evidence of recurrent aspiration
- Conditions known to be commonly associated with bronchiectasis, such as prior mycobacterium tuberculosis
- Have not had standard clinical evaluation to address other potential causes of chronic oto-sino- pulmonary disease, particularly cystic fibrosis, aspiration or airway anatomic abnormalities.
