It is also interesting that many seizure-related terms such as ‘focal impaired awareness seizure’ (p = 2.30 × 10−6), ‘epileptic encephalopathy’ (p = 3.40 × 10−5), and ‘focal-onset seizure’ (p = 1.67 × 10−3) were significant, which is consistent with the clinical finding that LGGs with IDH1 mutation tend to have seizures and can be related to patient survival [59]. This evidence concerns the gene IDH1 and Epileptic encephalopathy.
