There are three major histological subtypes of glioma (astrocytoma, oligoastrocytoma and oligodendroglioma) and SMC4 overexpression correlated with the reduced OS in astrocytoma and oligodendroglioma (Figure 3D, the top panel) and correlated with reduced PFI in astrocytoma and oligo-astrocytoma (Figure 3D, the bottom panel). The gene discussed is SMC4; the disease is oligoastrocytoma.
