IDH1 and glioblastoma: In the present study we also recorded cases whose MC scores changed between v11b4 and v12.5: from glioblastoma, IDH-wildtype (mesenchymal subtype) MC to GG MC (v12.5 version) or LGG MC in v12.5 and indeed clustered in DNT or GG cluster by t-SNE analysis; but we also observed cases that clustered with GB by t-SNE analysis.
