IGFBP6 and Behcet disease: After comparing the LDSC results of the five psychiatric disorders, we also detected four common plasma proteins shared by BD and SCZ, including tumor necrosis factor receptor superfamily member 1B (p value = 0.012 for BD, p value = 0.011 for SCZ), insulin-like growth factor-binding protein 6 (p value = 0.022 for BD, p value = 0.030 for SCZ), rho guanine nucleotide exchange factor 10 (p value = 0.022 for BD, p value = 0.044 for SCZ), and normal mucosa of esophagus-specific gene 1 protein (p value = 0.030 for BD, p value = 0.045 for SCZ; Table 2).
