Here, we used bulk expression data from the human DLPFC to (1) build gene coexpression modules and assess the cell type and biological process enrichments for modules containing DDR1 transcripts, (2) evaluate the association of these coexpression modules with SCZ and BD and (3) test the differential expression of DDR1 transcripts in patients with SCZ or BD with respect to HCs. The gene discussed is DDR1; the disease is Behcet disease.
