FURIN and glioblastoma: We selected 22 EGFR mutations detected in GBM samples by Liu et al. (2018) (TCGA PanCancer); these mutations were located in the growth factor receptor domain, protein kinase-like (PK-like), receptor L domain, growth factor receptor domain IV, furin-like cysteine-rich region, protein kinase-like (PK-like), and protein tyrosine kinase (Table 5, Supplementary Table 7).
