BLOC1S1 and Sepsis: Subsequently, the expression levels of these 10 genes in sepsis and control samples were analyzed in the training and validation sets, and the results showed that BLOC1S1, NDUFA1, and SFT2D1 were significantly different in the training and validation sets, and the AUC values for these three genes were ≥0.70 (P < 0.001) (Figure 3E).
