Of these 15 CpG sites, three (cg15578140 in microRNA 548f-3 (MIR548F3), cg09935388 in Growth Factor Independent Protein 1 (GFI1), cg04598670 (unknown gene)) showed potential causal associations with inflammatory bowel diseases and one (cg25189904 in Guanine Nucleotide Binding Protein Gamma 12 (GNG12)) with schizophrenia (PFDR < 0.05, Table 3). This evidence concerns the gene GNG12 and schizophrenia.
