Genes affected

DNAH17 (HGNC:2946): (dynein axonemal heavy chain 17) Dyneins are microtubule-associated motor protein complexes composed of several heavy, light, and intermediate chains. DNAH17 is a heavy chain associated with axonemal dynein (Milisav and Affara, 1998 [PubMed 9545504]).[supplied by OMIM, Mar 2008]
