In a larger study by Hawkins et al. of pediatric low-grade astrocytomas including 105 PAs, 6 PMAs, 71 diffuse astrocytomas, and 4 unspecified low-grade astrocytomas, BRAF fusions were described in 62% of PAs, 67% of PMAs, 37% of diffuse astrocytomas, and 50% of unspecified low-grade astrocytomas. This evidence concerns the gene BRAF and astrocytoma (excluding glioblastoma).
