Pathway analysis on the union of genes yields the pathway ‘Regulation of p53 activity through phosphorylation’ (FDR 1.13×10–2) (Supplementary file 13), including the FOXO1 AT-schizophrenia/control cohort DEG regulatees CCNA1, BLM, TP53RK, and RBBP8, and the AT-schizophrenia/control cohort-specific DEGs PRKAA1 and TAF15 (Supplementary file 13). Here, PRKAA1 is linked to schizophrenia.
