Specifically, a 24-year-old female with an IDH-wildtype high grade glioma harbored two fusions involving BCOR, namely BCOR-L3MBTL2 as well as EP300-BCOR, the latter with two distinct breakpoints detected (Fig. 4b); a 30-year-old with anaplastic astrocytoma, IDH-mutant, harbored a CREBBP-SRRM2 fusion (Fig. 4c); and a 45-year-old with anaplastic astrocytoma, IDH-wildtype, harbored a CREBBP-GOLGA6L2 fusion (Fig. 4d). The gene discussed is EP300; the disease is anaplastic astrocytoma.
