EGFR and malignant glioma: Several common genetic alterations, such as EGFR (epidermal growth factor receptor) amplifications on chromosome 7p, as well as losses on 9p (p16), 10q (PTEN, or phosphatase and tensin homolog deleted on chromosome 10), and 17p (p53) have been identified in a significant proportion of patients with malignant gliomas (reviewed thoroughly in [8]).
