ERICH1 and myasthenia gravis: 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).
