Mutations in AKT1, KLF4, POLR2A or SMO were mostly detected in meningothelial or transitional meningioma, except for three cases: one case of angiomatous meningioma with KLF4 mutation, one case of secretory meningioma with KLF4 mutation and one case of psammomatous meningioma with AKT1 mutation. This evidence concerns the gene SMO and Psammomatous Meningioma.
