One CpG site showed significant colocalization: cg08170519 is located in IGSF9B, a gene involved in GABA neurotransmission/inhibitory synapse development and Vitamin D receptor pathway processes, which have been repeatedly implicated in schizophrenia (Cui, McGrath, Burne, & Eyles, 2021). This evidence concerns the gene VDR and schizophrenia.
