FABP7 and oligodendroglioma: Furthermore, when we evaluated in separated samples including astrocytoma, oligodendrocytoma, and oligodendroglioma, high frequency of FABP7‐upregulated expression was observed in IDH1wt of all types of tumors (19 of 20 in astrocytoma, 6 of 6 in oligodendrocytoma, 2 of 2 in oligodendroglioma) (Table 2).
