BRAF and Rhabdoid Meningioma: In the present study we focused our ctDNA analysis in searching for mutations in the genes NF2, phosphatidylinositol-4,5-bisphosphate 3-kinase catalytic subunit α (PIK3CA), frizzled class G protein-coupled receptor (SMO) and v-Raf murine sarcoma viral oncogene homolog B1 (BRAF), the latter although rare, has been reported in rhabdoid meningiomas (5, 6).
