EML6 and schizophrenia: EML6 is a Microtubule Associated Protein [60, 61] potentially related to cilium organization and movement [94] and, while the role of midbrain ependymal cells in modulating the number of calbindin neurons in schizophrenia is not clear, the beating of ependymal cilia along the lateral ventricle is probably involved in neurogenesis [95].
