| Low grade glioma, WHO grade I
| Pilocytic astrocytoma/pilomyxoid astrocytoma
| Some tumors show polysomy 7; other polysomies more common in adult PA
| '''Fusions:''' KIAA1549-BRAF fusion (via 3'BRAF duplication), other BRAF partners reported; NTRK fusions (rare); FGFR1 fusions (rare); '''Mutations:''' BRAF V600E (particularly extra-cerebellar tumors); FGFR1 (midline PA); NF1 (esp. germline), other MAPK pathway mutations '''Loss:''' NF1 in optic pathway PA
| Classic PA are cerebellar (most commonly associated with BRAF duplication); PA in patients with germline NF1 alterations often develop as optic gliomas;Surgical resection can be curative; PMA generally more aggressive than PA; BRAF fusions and BRAF mutations generally are mutually exclusive
