Furthermore, Nek1 and Cep104 are involved in the stabilization of the ciliary axoneme or in cilia formation and elongation (Jiang et al., 2012, Satish Tammana et al., 2013, Shalom et al., 2008, Thiel et al., 2011, Wang et al., 2014), and mutations in both cause ciliopathies (El Hokayem et al., 2012, Monroe et al., 2016, Srour et al., 2015, Thiel et al., 2011). Here, CEP104 is linked to ciliopathy.
