MAGED2 mRNA was highest in glioblastoma (p < 0.001), and diffuse astrocytoma had the second-highest value (p < 0.001)—followed by oligodendroglioma (p < 0.001) and anaplastic astrocytoma (p < 0.001)—when compared with normal brain tissue. This evidence concerns the gene MAGED2 and oligodendroglioma.
