We previously showed that Tau tubulin kinase 2 (TTBK2), a kinase causally mutated in the hereditary neurodegenerative disorder spinocerebellar ataxia type 11 (SCA11) (Houlden et al., 2007), is an essential regulator of ciliogenesis (Goetz et al., 2012). The gene discussed is TTBK2; the disease is spinocerebellar ataxia type 11.
