We observed that the mRNA expression of 13 ATGs (ATG3, ATG4A, ATG4C, ATG5, ATG7, ATG9B, ATG10, ATG12, ATG16L1, ATG2A, ATG2B, ATG9A and ATG16L2) were closely associated with the OS of glioma patients (Fig. 1a and Additional file 2: Figure S2). The gene discussed is ATG2A; the disease is central nervous system cancer.
