In addition to NF2 mutations, somatic mutations of tumor necrosis factor receptor-associated factor 7 (TRAF7), DNA-directed RNA polymerase 2 subunit RPB1 (POLR2A), Protein Kinase A Type 1a Regulatory Subunit (PRKAR1A), Phosphatidylinositol-4,5-Bisphosphate 3-Kinase Catalytic Subunit Alpha (PIK3CA), Kruppel-Like Factor 4 (KLF4), AKT Serine/Threonine Kinase 1/Protein Kinase B (AKT1), Smoothened Frizzled Class Receptor (SMO), Suppressor Of Fused Homolog (SUFU), and genes of the transforming growth factor beta pathway (TGFβ) among others have been detected in meningiomas. This evidence concerns the gene PRKAR1A and meningioma.
