A further case, a compact and necrotic tumor with perivascular radiating arrangements (Figure S2B), displayed a methylation classifier score strongly indicative of a high-grade neuroepithelial tumor with MN1 alteration (CNS HGNET-MN1, methylation classifier score = 0.713) (Figure S2C). This evidence concerns the gene MN1 and neuroepithelial neoplasm.
