ROC curve analysis showed that the MG dysregulated gene co-expression module-based model showed excellent diagnostic efficacy for MG (AUC = 0.981, Figure 4D), and some of these genes, such as NAPB, showed significantly high expression in MG, while C5orf25 and ERICH1 showed significantly low expression in MG (Figure 4E). This evidence concerns the gene NAPB and myasthenia gravis.
