When many people hear Primary Ciliary Dyskinesia (PCD), they picture a child with chronic infections, constant congestion, or a persistent wet cough.

But PCD doesn't end when childhood does.

PCD is a lifelong genetic condition, and adults make up a substantial part of the PCD population. Some adults were diagnosed in childhood and have spent decades managing the disease. Others reach adulthood after years of being told their symptoms were asthma, allergies, recurrent bronchitis, chronic sinusitis, or simply “getting sick a lot.”

That makes adult PCD an important—and

PCD is not one uniform condition.

More than 50 different genes have been associated with PCD, and these genes can affect the structure, assembly, or movement of cilia in different ways.

As a result, two people with PCD may have very different symptoms, disease severity, and complications.

One person may have severe respiratory problems beginning shortly after birth, while another may

For people living with Primary Ciliary Dyskinesia (PCD), keeping mucus moving is a daily part of protecting the lungs.

PCD is a genetic condition that affects the tiny, hair-like structures called cilia that normally help move mucus, bacteria, and other particles out of the respiratory tract. When those cilia don't work properly, mucus can remain trapped in the airways, contributing to

When people think about Primary Ciliary Dyskinesia (PCD), they often think of chronic cough, recurrent respiratory infections, sinus problems, and the daily work required to keep mucus moving.

PCD is a lifelong genetic condition in which abnormal or dysfunctional cilia interfere with the body's ability to clear mucus, bacteria, and other particles from the respiratory tract.

But there is a lesser-known phenomenon described within
