Meningiomas are the most common primary brain tumors in adults. Located within the layer of tissue covering the brain, these tumors are usually slow-growing and benign but can cause serious neurological complications. About half of these tumors have mutations in the neurofibromin 2 gene (NF2). To identify other genes that contribute to meningioma pathogenesis, Clark et al. performed genome sequence analysis on 300 tumors. Meningiomas fell into two general classes: benign tumors located at the skull base—which tend to harbor mutations in the TRAF7, KLF4, AKT1, and SMO genes—and higher-grade tumors located in the cerebral and cerebellar hemispheres that harbor mutations in NF2.
