EGFR and cancer: Other DNA mutations were also reported, including abnormalities commonly found in other cancers, such as EGFR (epidermal growth factor receptor), HRAS (HRas Proto-Oncogene, GTPase), TP53, RB1 (retinoblastoma protein), ATM (ATM Serine/Threonine Kinase), and PIK3CA (Phosphatidylinositol-4,5-Bisphosphate 3-Kinase Catalytic Subunit Alpha) (Table 1 and Figure 3) [18,19,20,21,22,23,24,25].
