Multiple genes revealed to have an important prognostic value, with significant effects on survival probability of LGG (including the genes DRG2, LRRC41, NADK, PPP1R8, and C14orf23) and GBM patients (including the genes THRAP3, PSMB2, and MAPKAP1). This evidence concerns the gene LRRC41 and glioblastoma.
