The ITGB8 showed the highest predictive capacity (AUC = 0.889, 95%CI = 0.850–0.927) for PCa, followed by hsa-miR-30b (AUC = 0.739, 95%CI = 0.657–0.820), hsa-miR-21 (AUC = 0.737, 95%CI = 0.672–0.801) and ELOVL7 (AUC = 0.607, 95%CI = 0.529–0.685) (Figure 5B). The gene discussed is ELOVL7; the disease is posterior cortical atrophy.
