EGFR and schizophrenia: Though not directly included as a KEGG term, schizophrenia (SCZ) and autism spectrum disorder (ASD) have strong associations with multiple genes co-expressed with Cck. These mechanisms include OXPHOS, as well as genes associated to the well-known neuregulin (NRG)-ERBB pathway (Fig. 7c) [58–60], and motivated further analyses in human tissue [61–64].
