Of the genes in the Tan schizophrenia module, 18 genes (YARS, AARS, MAGED1, HSP90AB1, AKR1B1, NUP93, SNX17, DDOST, PSMB2, NCALD, ACOT7, IMP3, SARS, GLG1, COMT, MXD4, GPR177, ARAF) do overlap with co-expression modules constructed using brain tissue and associated with schizophrenia previously [15]. This evidence concerns the gene GLG1 and schizophrenia.
