Genes affected

CDCA7L (HGNC:30777): (cell division cycle associated 7 like) Acts upstream of or within positive regulation of cell population proliferation. Located in cytosol; fibrillar center; and nucleoplasm. [provided by Alliance of Genome Resources, Apr 2022]

DNAH11 (HGNC:2942): (dynein axonemal heavy chain 11) This gene encodes a ciliary outer dynein arm protein and is a member of the dynein heavy chain family. It is a microtubule-dependent motor ATPase and has been reported to be involved in the movement of respiratory cilia. Mutations in this gene have been implicated in causing Kartagener Syndrome (a combination of situs inversus totalis and Primary Ciliary Dyskinesia (PCD), also called Immotile Cilia Syndrome 1 (ICS1)) and male sterility.
