IDH1 and central nervous system cancer: Similarly, we assembled 71 gliomas with a wide range of cell types and WHO grades, namely, WHO grades 1 to 4; IDH1‐mutant, IDH1‐mutant, and 1p/19q‐codeleted or IDH1‐wildtype; and the most commonly occurring types of adult gliomas, astrocytoma, oligodendroglioma, and GBM.[21] No significant differences in age or sex (Mann‐Whitney U test, p > 0.05) were found between the two kinds of tumors (Figure S1B,C, Supporting Information).
