Genes affected
NEK4 (HGNC:11399): (NIMA related kinase 4) The protein encoded by this gene is a serine/threonine protein kinase required for normal entry into replicative senescence. The encoded protein also is involved in cell cycle arrest in response to double-stranded DNA damage. Finally, this protein plays a role in maintaining cilium integrity, and defects in this gene have been associated with ciliopathies. [provided by RefSeq, Jan 2017]

Ciliopathy Pathogenic:1
Likely pathogenic, no assertion criteria providedresearchDepartment Of Translational Genomics (developmental Genetics Section), King Faisal Specialist Hospital & Research Centre-Loss of function, autozygosity mapping. NEK4 interacts with the known ciliopathy protein RPGRIP1L (mutations in RPGRIP1L are causative for Joubert and Meckel syndrome), is localized to the basal body in ciliated cells and its deficiency impairs cilium assembly (Coene et al. 2011). -
