CRBN and Intellectual disability: Many of the CpGs identified in the analysis in the SSRI-treated PND group are found in the promoter region of Cereblon (CRBN), MyoD Family Inhibitor Domain Containing (MDFIC), Cyclin-Dependent Kinase 11B (CDK11B), and Mitogen-Activated Protein Kinase Kinase Kinase Kinase 5 (MAP4K5) genes. The CRBN gene has been shown to be involved in intellectual disabilities [39] and has immunomodulatory functions [40].
