Primary ciliary dyskinesia (PCD) is a genetically heterogeneous disorder characterized by abnormally functioning cilia. The main clinical signs are recurrent or persistent respiratory infections because of the lack of effective ciliary motility causing abnormal mucociliary clearance.[1] The dysfunction of the monocilia of the embryonic node might also lead to the randomization of the left-right body asymmetry and transposition of the thoracic and abdominal organs in 50% of the cases called the Kartagener's syndrome.[2] Male fertility can be impaired because of defects of the spermatozoa flagella. Disorders such as hydrocephalus or serous otitis have occasionally been reported. (from Merveille et al, 2014)
