FGFR1 and neuroepithelial neoplasm: A previous multicenter study (7) of 56 low-grade neuroepithelial tumors identified 35 tumors in the cerebral cortex carrying FGFR1 mutations (n = 10, 29%), BRAF mutations (n = 7, 20%), and MYB/MYBL1 alterations (n = 9, 26%), and another multicenter series of 91 low-grade neuroepithelial tumors reported FGFR1 mutations (n = 30, 33%), BRAF V600E mutations (n = 10, 11%), MYB/MYBL1 alterations (n = 22, 24%), and other mutations (n = 29, 32%) (5).
