This miRNA has previously been associated with depression, whereby it was found to be downregulated in PBMCs in individuals with MDD, and was further found to regulate the depression‐associated glutamate metabotropic receptor 4 (GRM4) and was upregulated in response to treatment with the antipsychotic citalopram (J. Li et al., 2015). Here, GRM4 is linked to major depressive disorder.
