G34R/G34V mutations are less common (approximately 10 % of pediatric glioblastoma), and are limited to non-brainstem tumors. Molecular Pathology • Low-grade/diffuse astrocytoma (WHO grade II) ° Aberrations of MYB, MYBL1, or FGFR1/3 (tyrosine kinase [TK] domain duplication, missense mutation, or TACC1/3 fusion) are detectable in almost 70 % of low-grade or diffuse astrocytomas. FGFR1 TK domain duplications and MYB or MYBL1 alterations occur nearly exclusively in cerebral lesions; 25 % of cerebral pediatric low-grade or diffuse astrocytomas will harbor MYB or MYBL1 abnormalities, with a similar percentage having FGFR1 aberrations.
