The potential role of miRNAs in psychiatric disorders has recently been highlighted by GWS association findings with SNPs within miR‐137 and SCZ.13 Several reports have implicated microRNAs in BD, both genetically and biologically.11, 23, 25, 26, 39, 40 The PGC‐BD group performed a combined analysis of GWAS data that identified a GWS intronic variant in ODZ4 (TENM4), rs12576775.9 This association has been confirmed by two other independent studies.10, 11. The gene discussed is TENM4; the disease is psychiatric disorder.
