Mutual exclusivity of NF1 and EGFR alterations in IDH-wildtype glioblastoma was further substantiated using two publicly available resources, TCGA and CPTAC, totaling 368 genomically-characterized glioblastomas after excluding samples with pathogenic IDH1/2 alterations (Supplementary Table 3–4) [21–24]. The gene discussed is EGFR; the disease is glioblastoma.
