悪性神経膠腫におけるイソクエン酸デヒドロゲナーゼ遺伝子および他の遺伝子の遺伝子変化

摘要

We found mutations of the R132 residue of isocitrate dehydrogenase 1 (IDH1) in the majority of grade II and III astrocytomas and oligodendrogliomas as well as in glioblastomas that develop from these lower grade lesions. Those tumors without mutations in IDH1 often had mutations at the analogous R172 residue of the closely related IDH2 gene. These findings have important implication for the pathogenesis and diagnosis of malignant gliomas.
