Furthermore, SLC40A1 displayed moderate discriminatory power in distinguishing overall asthma [area under the ROC (AUC) = 0.79] and non-allergic asthma (AUC = 0.70) from controls, and high discriminatory power to distinguish between allergic asthma and controls (AUC = 0.87) (Figure 6G). This evidence concerns the gene SLC40A1 and asthma.
