Using the data available on TCGA and the EPIC software, we also analyzed the possible correlation between the expression of the ITGAE and CD69 genes and molecular markers of GBM (Isocitrate Dehydrogenase 1 (IDH1), Isocitrate Dehydrogenase 2 (IDH2), Alpha-Thalassemia/mental Retardation, X-linked (ATRX), and Tumor Protein P53 (TP53)). The gene discussed is IDH2; the disease is Intellectual disability.
