CDKN2A and astrocytoma (excluding glioblastoma): Based on this hypothesis, we examined the multi-gene proliferation score (MGPS) between Astrocytoma samples with and without CDKN2A/B homozygous deletion, and found Astrocytoma samples with CDKN2A/B homozygous deletion showed elevated MGPSs, suggesting their fast proliferation feature (Supplementary Fig. 11C).
