Heterozygous mutations in either the R132 residue of isocitrate dehydrogenase I (IDH1) or the R172 residue of IDH2 in human gliomas were recently highlighted. Heterozygous mutations in the IDH1 occur in the majority of grade II and grade III gliomas and secondary glioblastomas and change the structure of the enzyme, which diminishes its ability to convert isocitrate (ICT) to alpha-ketoglutarate (alpha-KG) and provides it with a newly acquired ability to convert alpha-KG to R(-)-2-hydroxyglutarate [R(-)-2HG]. The IDH1 and IDH2 mutations are relevant to the progression of gliomas, the prognosis and treatment of the patients with gliomas harboring the mutation. In this paper, we reviewed these recent findings which were essential for the further exploration of human glioma cancer and might be responsible for developing a newer and more effective therapeutic approach in clinical treatment of this cancer.
