Entrez Gene Summary for DNAI2 Gene

  • The protein encoded by this gene belongs to the dynein intermediate chain family, and is part of the dynein complex of respiratory cilia and sperm flagella. Mutations in this gene are associated with primary ciliary dyskinesia type 9. Alternatively spliced transcript variants encoding different isoforms have been noted for this gene. [provided by RefSeq, Mar 2010]

GeneCards Summary for DNAI2 Gene

DNAI2 (Dynein, Axonemal, Intermediate Chain 2) is a Protein Coding gene. Diseases associated with DNAI2 include ciliary dyskinesia, primary, 9, with or without situs inversus and primary ciliary dyskinesia 9: dnai2-related primary ciliary dyskinesia. Among its related pathways are Respiratory electron transport, ATP synthesis by chemiosmotic coupling, and heat production by uncoupling proteins.. GO annotations related to this gene include microtubule motor activity. An important paralog of this gene is WDR63.

Disorders for DNAI2 Gene

(1) OMIM Diseases for DNAI2 Gene (605483)


  • 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.
