Type Species Amino acid change Nucleotide change Description Reference
Missense Human R132C, R132G, R132S, R132H, R132L 394C>T, 394C>G, 394C>A, 395G>A, 395G>T IDH1 mutations associated with cancers such as glioma and some hematological malignancies. 8,10
Clinically-Relevant Mutations and Pathophysiology Comments
The majority (80-90%) of IDH1 mutations in glioma are R132H. IDH1 is mutated in the majority of lower grade diffuse gliomas (grades II-III) and also in most secondary glioblastomas. It is rare in newly diagnosed glioblastoma.
