Many common biomolecules in glioblastoma (GBM) affect patient outcomes, including isocitrate dehydrogenase 1/2 (IDH 1/2), TP53, alpha thalassemia/mental retardation syndrome X-linked (ATRX), and O6-methylguanine DNA methyltransferase (MGMT) which contain genetic alterations [3–5]. The gene discussed is MGMT; the disease is glioblastoma.
