[Congenital ciliary dyskinesia. Focus]

Abstract

Primary ciliary dyskinesia (PCD) is a rare autosomal recessive disease, caused by specific primary structural and/or functional abnormalities of the motile cilia. Prevalence, about 1/15,000 to 1/30,000, is probably underestimated, as diagnosis might not be evocated in absence of Kartagener syndrome. Diagnosis is confirmed in presence of abnormal ciliary motility as well as ciliary ultrastructure. Disease-causing mutations in at least 16 genes have already been identified; analysis will be guided by the type of ultrastructural abnormalities. An early and adequate diagnosis and therapy can theoretically improve the prognosis of the disease.
