IDH2 and neoplasm: When analyzed for IDH mutation status alone (IDH mutated vs IDH wild-type) we found no differences when it came to distance to the SVZ from neither the tumor center (p = 0.055, median distance 18.7 mm vs 14.9 mm) nor tumor border (p = 0.752, median distance was 0 mm for both groups) (Fig. 2c).
