N = 19; RBFOX1, RBFOX2, RBFOX3, or CELF4 regulatory networks; genes whose mRNAs are bound by FMRP; synaptic genes; genes involved in neuronal morphogenesis; genes involved in neuron projection; genes associated with schizophrenia; genes involved in CNS neuron differentiation; genes encoding voltage‐gated calcium channels; genes involved in cytokine and immune response; genes known to bind to the retinoid X receptor. This evidence concerns the gene CELF4 and schizophrenia.
