Interestingly, the top disease processes were neurological and psychological disorders, caused by differential expression of a number of genes implicated in SZ, BD and ASD, including ZNF804A, which decreased 1.7-fold, SMARCA2, which increased 1.7-fold, as well as BAG3, KAT2A, HIST1H2BD, SLC6A8, and SLC17A7, which were induced by HS, and PRODH, ARNT2, DPP10, AHI1, IFITM1 and RORA, which decreased (described in detail in the discussion section). Here, SMARCA2 is linked to Behcet disease.
