Involvement in diseasei

Ciliary dyskinesia, primary, 13 (CILD13)3 Publications
The disease is caused by mutations affecting the gene represented in this entry.
Disease descriptionA 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. At ultrastructural level, CILD13 is characterized by a marked reduction or absence of both dynein arms from the patients cilia.
