This report describes general characteristics of the group of diseases classified as ciliary dyskinesia, primary (CILD). Primary ciliary dyskinesia is a genetically heterogeneous disorder, with multiple genes and mapped loci. A comprehensive list of CILD subtypes as defined by OMIM (which number over 40 to date) may be found by following the link in the "Related Diseases" section, "OMIM phenotypic series" subsection, below. A subset of these are listed in the table of related diseases, with links to more detailed reports for subtypes that have been investigated using fly models.

Primary ciliary dyskinesia is a disorder characterized by chronic respiratory tract infections, abnormally positioned internal organs, recurrent ear infections (especially in children) and infertility (especially in males). About 50 percent of people with primary ciliary dyskinesia have a mirror-image reversal of their internal organs (situs inversus).

Primary ciliary dyskinesia usually follows autosomal recessive genetic inheritance. [from Genetics Home Reference, primary ciliary dyskinesia; 2016.11.21]
Primary ciliary dyskinesia is a genetically heterogeneous autosomal recessive disorder.
Primary ciliary dyskinesia results from loss of function of different parts of the primary ciliary apparatus, most often dynein arms.
