  • Ciliary dyskinesia, primary, 9 (CILD9) [MIM:612444]: A disorder characterized by abnormalities of motile cilia. Respiratory infections leading to chronic inflammation and bronchiectasis are recurrent, due to defects in the respiratory cilia; reduced fertility is often observed in male patients due to abnormalities of sperm tails. Half of the patients exhibit randomization of left-right body asymmetry and situs inversus, due to dysfunction of monocilia at the embryonic node. Primary ciliary dyskinesia associated with situs inversus is referred to as Kartagener syndrome. {ECO:0000269 PubMed:18950741, ECO:0000269 PubMed:25186273}. Note=The disease is caused by mutations affecting the gene represented in this entry.
