Interestingly, MIR137, which encodes a microRNA, regulates several other schizophrenia risk genes, notably ZNF804A (http://www.genecards.org/cgi-bin/carddisp.pl?gene=ZNF804A) and TCF4 (http://www.genecards.org/cgi-bin/carddisp.pl?gene=TCF4) (Kim et al., 2012, Guella et al., 2013, Kwon et al., 2013, Wright et al., 2013). The gene discussed is TCF4; the disease is schizophrenia.
