The ROC curves showed that aside from HLA-DMA (AUC, 0.6759 in GSE99325 and AUC, 0.6235 in GSE104954), PRKCB (AUC, 0.6000 in GSE104954), and HLA-B (AUC, 0.6706 in GSE104954), the genes had relatively high AUCs (>0.7) in the diagnosis of DN, especially CAV1 (AUC, 0.8704 in GSE99325; AUC, 0.8706 in GSE104954), COL1A2 (AUC, 0.8148 in GSE99325; AUC, 0.9059 in GSE104954), VWF (AUC, 0.8426 in GSE99325; AUC, 0.8353 in GSE104954), FN1 (AUC, 0.8241 in GSE99325; AUC, 0.8588 in GSE104954), and ITGB2 (AUC, 0.8056 in GSE99325; AUC, 0.8000 in GSE104954) (Figure 8). Here, CAV1 is linked to liver dysplastic nodule.
