EZH2 and meningioma: Molecular analyses performed in the CNS WHO grade 3 meningioma cohort revealed that the examined alterations overall occur with a higher frequency in EZH2-high tumors (Figure 2A; considering only those cases in which all molecular tests could be performed, the proportions of tumors without any alteration were 1/17 and 7/18 in EZH2-high and EZH2-low groups, respectively; P = .0408, Fisher’s exact test).
