TRAF7 and Angiomatous Meningioma: To determine if established cancer genes are mutated in angiomatous meningioma, we sequenced all exons from 560 cancer associated genes (Tables S1 and S2) and performed amplicon sequencing of all exons from TRAF7 and the exon encoding the KLF4 K409 amino acid residue that were not present in the OPv2 gene set (Table S1).
