Figure 1. IDH1 mutations in pGBMs.

Figure 1

All mutations by pyro-sequencing analysis were located at codon 132. And 89.5% of them were G395A transition (Arg→His), followed by C394A transversion (Arg→Ser; 10.5%) (A). Kaplan-Meier Survival Analysis showed that pGBM patients carrying an IDH1 mutation (dotted line) had significantly longer progression free survival (p = 0.026; log-rank test) and overall survival (p = 0.029; log-rank test) (B).
