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]. The gene discussed is PSMB2; the disease is schizophrenia.
