The results showed that the proportion of IDHR132H+ tumor cells in IDH‐mutated gliomas was significantly higher than that in the wild‐type group (Figure 1D), and the proportion of ATRX+ tumor cells in ATRX‐mutated gliomas was significantly lower than that in the wild‐type group (Figure 1D). This evidence concerns the gene ATRX and central nervous system cancer.
