The pathogenesis of glioma often involves dysregulated signaling in key oncogenic pathways, such as constitutive PI3K/AKT activation, EGFR amplification/overexpression, and other aberrant growth factor signals (Woo et al., 2020; Zhao et al., 2021; The Cancer Genome Atlas Research Network, (2008)). The gene discussed is EGFR; the disease is glioma.
