Figure 2c shows that, in 17 GBM tumors (HF series), MTA levels do not differ significantly between homozygous MTAP-deleted and MTAP-intact tumors (~1.4-fold higher median MTA levels in MTAP-deleted tumors; p = 0.20, unpaired 2-tailed t test with unequal variance). This evidence concerns the gene MTAP and glioblastoma.
