How do I know if I have Primary ciliary dyskinesia?

TL;DR: Primary ciliary dyskinesia is a rare genetic condition where the microscopic, hair-like structures in your airways, sinuses, and ears do not move properly, leading to chronic respiratory and ear infections. If you experience a lifelong history of persistent wet cough, recurring sinus infections, and unexplained fertility issues, you should consult a pulmonologist or an ENT specialist for specialized testing.

What are the early signs and symptoms of Primary ciliary dyskinesia?

Because Primary ciliary dyskinesia affects the cilia (tiny, hair-like structures) throughout the body, the symptoms are often present from birth. A key indicator is respiratory distress in newborns that cannot be explained by other causes. As children and adults, individuals with Primary ciliary dyskinesia often experience a chronic, productive "wet" cough that persists regardless of the season. Other common patterns include:

• Chronic nasal congestion and recurring sinus infections (sinusitis).


• Frequent ear infections (otitis media) leading to potential hearing loss.


• Bronchiectasis, which is the permanent widening and scarring of the airways.


• Situs inversus, a condition where the major organs are mirrored in their placement (seen in approximately 50% of people with Primary ciliary dyskinesia).


• Fertility challenges, as cilia are also necessary for sperm motility and the movement of the egg through the fallopian tubes.

How can I perform a self-assessment for Primary ciliary dyskinesia?

While only a clinician can diagnose Primary ciliary dyskinesia, you can track your health patterns to prepare for an appointment. Look for symptoms that have been present since childhood, rather than those that appeared suddenly in adulthood. Ask yourself: Have I had a "wet" cough for as long as I can remember? Do I have a history of chronic ear tubes or recurring sinus surgeries? If you have had these issues, alongside a family history of similar respiratory problems, it is important to document these patterns in a symptom diary to share with your physician.

When should I see a doctor and what tests should I request?

If you suspect you have Primary ciliary dyskinesia, it is time to see a pulmonologist, preferably one who specializes in rare lung diseases or interstitial lung disease. Because this condition is often misdiagnosed as asthma or chronic bronchitis, you must be specific. Ask your doctor about the following diagnostic path:

1. Nasal Nitric Oxide (nNO) screening: A simple, non-invasive test where low levels of nasal nitric oxide strongly suggest the condition.


2. High-speed video microscopy: A biopsy of the nasal or bronchial lining to observe how the cilia move.


3. Genetic testing: A panel specifically looking for mutations in the genes known to cause Primary ciliary dyskinesia (such as DNAH5 or DNAI1).


4. Transmission electron microscopy (TEM): To look at the internal structure of the cilia.

What are the red flags that require urgent medical attention?

Seek medical care immediately if you experience significant shortness of breath, coughing up blood (hemoptysis), or signs of a severe lung infection such as high fever and chest pain. While Primary ciliary dyskinesia is a chronic condition, sudden changes in your respiratory baseline should always be evaluated by a medical professional to prevent further lung damage.

How can I advocate for myself if my concerns are dismissed?

Rare diseases are often overlooked in primary care settings. If you feel your concerns are not being heard, bring printed information from reputable sources like the NIH or the 66-member community at DiseaseMaps.org. Request a referral to a center of excellence that specializes in ciliary disorders. Remember, you are the expert on your own body; persistent advocacy is often necessary when dealing with rare conditions.

Next steps

• Start a symptom log detailing the duration and frequency of your respiratory and ear issues.


• Request a referral to a pulmonologist with experience in rare airway diseases.


• Connect with the Primary ciliary dyskinesia community at DiseaseMaps.org to share experiences with others who have navigated the diagnostic journey.


• Ask your doctor specifically about a nasal nitric oxide test as an initial screening tool.
