The transcription factor enrichment analysis revealed distinct regulatory programs driving each disorder: MDD pathology appears regulated by ASCL3, MYOG, HNF1B, RUNX3, FOXA1 and STAT4; BD exhibited predominant control by immune-regulatory factors including FOSL1, FOSL2, PLSCR1, RELB, BATF3, IRF and NFKB1; while SCZ demonstrated unique regulation through ATF5, CREB3L3, SNAI1, NFIL3, CEBPB, RELB and IRF transcription factors. This evidence concerns the gene FOSL2 and Behcet disease.
