All three sets of module genes include well-studied candidate genes for schizophrenia (e.g., DTNBP1), glutamate receptors (e.g., GRIN1), several genes located in the MHC region (e.g., HIST1H1A, HIST1H1C, HIST1H2AB, HIST1H2BB, HLA-E), and genes from the 14-3-3 protein family (e.g., YWHAQ, YWHAZ). The gene discussed is YWHAQ; the disease is schizophrenia.
