In C1-GBM, key tumor driver genes included BIRC3 (Baculoviral IAP Repeat Containing 3), MET (MET Proto-Oncogene, Receptor Tyrosine Kinase), COL1A1 (Collagen Type I Alpha 1 Chain), CR1 (Complement C3b/C4b Receptor 1), and IL7R (Interleukin 7 Receptor). This evidence concerns the gene IL7R and glioblastoma.
