It was reported that high percentages of IDH1 and IDH2 mutations (70%–80%) had been found in a high percentage of LGG and less in high‐grade gliomas,25, 26 and TP53 mutations are observed in about 30% of gliomas, mainly LGG,27 which was similar to the results in the present study. This evidence concerns the gene TP53 and glioma.
