We found that the high expression of C1R, CCL2, and TNFRSF1A genes was particularly associated with the low survival in GBM patients (Figure 5), while other 41 DEGs enriched in the pathway of coronavirus disease-COVID-19 were not significantly connected with the overall survival of GBM patients (Supplementary Table S1). The gene discussed is C1R; the disease is glioblastoma.
