11 genes showed a negative direction of Wald ratio effect indicating a relationship between decreased gene expression and increased schizophrenia risk (FTCDNL1, FURIN, AC243562. 2, AC105749. 1, PCCB, PTPRU, THOC7, LINC02210, GATAD2A, FAM85B and FAM86B3P). This evidence concerns the gene THOC7 and schizophrenia.
