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]. Here, MXD4 is linked to schizophrenia.
