To annotate the module genes which had been reported to be associated with schizophrenia, we searched two genetic databases: GWAS Catalog [42] and SZGene [43], and found that four genes (MAD1L1, SDCCAG8, MCC and VAT1L) had been reported their susceptibility with SZ by GWAS [11, 44–46], and three genes (MAPK14 [47], MYH9 [48] and FXYD6 [49]) had been reported at least one positive association in SZGene. This evidence concerns the gene MCC and schizophrenia.
