  14. Slide 14: DIPG is genetically heterogenous

    DIPG is genetically heterogenous • 80-90% of DIPG cases harbour a lysine-to- methionine (K-to-M) mutation in histone 3 (H3) at amino acid 27 (H3K27M), and this may be considered the defining genetic alteration of DIPG • Additional mutations are necessary to drive glioma formation: Proliferative gene
