MIR6756 and schizophrenia: However, TS identified several miRNA encoding genes that were missed by the other methods, such as MIR4256, MIR6756, MIR3652, MIR4700, and MIR624. Due to the growing evidence regarding miRNA involvement in psychiatric disorders, some of these genes may be relevant to schizophrenia etiology, and thus may warrant further research.
