Primary ciliary dyskinesia

Primary ciliary dyskinesia (PCD), also immotile ciliary syndrome or Kartagener syndrome, is a rare, ciliopathic, autosomal recessive genetic disorder that causes defects in the action of cilia lining the respiratory tract (lower and upper, sinuses, Eustachian tube, middle ear) and fallopian tube, as well as in the flagella of sperm cells. The phrase "immotile ciliary syndrome" is no longer favored as the cilia do have movement, but may be inefficient or unsychronized.
