In the PD dataset GSE49036, CD14 (AUC = 0.713), C1QB (AUC = 0.744), CD53 (AUC = 0.831), LY96 (AUC = 0.775), P2RX7 (AUC = 0.863), C3 (AUC = 0.716), and TNFSF13B (AUC = 0.803) also exhibited good diagnostic efficiency in differentiating patients with PD from controls (Figure 6F). This evidence concerns the gene C3 and Parkinson disease.
