Therefore, PTEN is a target of 10q loss, and PTEN alterations are associated with aggressive tumor phenotypes regardless of chemosensitivity (Sasaki et al., 2001). In addition to the aforementioned pathways, homozygous and the less common hemizygous losses of 9p21 have been reported with high frequencies in gliomas, and up to 55% in AO (Maruno et al., 1996; Perry et al., 1999; Rasheed et al., 2002; Ohgaki and Kleihues, 2009; Michaud et al., 2018).

Daumas-Duport C, Scheithauer BW, Chodkiewicz JP, et al. This in turn provides evidence that IDH mutations could allow cells to remain in a vulnerable state, and prone to additional DNA alterations.
