NCI Definition: A grade I or grade II astrocytic tumor. This category includes pilocytic astrocytoma (grade I), subependymal giant cell astrocytoma (grade I), and diffuse astrocytoma (grade II). [1]

Low grade astrocytic tumors most frequently harbor alterations in BRAF, KIAA1549, NF1, FGFR1, and CIC [2].

Most Commonly Altered Genes in Low Grade Astrocytic Tumor

BRAF Fusion, KIAA1549-BRAF Fusion, BRAF-KIAA1549 Fusion, KIAA1549 Fusion, and BRAF Mutation are the most common alterations in low grade astrocytic tumor [2].
