An integrated genomic analysis of human glioblastoma multiforme. A selective R132H-IDH1 inhibitor (AGI-5198) identified through a high-throughput screen blocked, in a dose-dependent manner, the ability of the mutant enzyme (mIDH1) to produce R-2-hydroxyglutarate (R-2HG). It is also found in cellular structures called peroxisomes, which are small sacs within cells that process many types of molecules. Sasaki et al. Genomic landscapes and clonality of de novo AML. The IDH1 gene mutations that cause Maffucci syndrome are somatic, which means they occur during a person's lifetime and are not inherited. Introduction of either mutant IDH or cell-permeable 2HG was associated with repression of the inducible expression of lineage-specific differentiation genes and a block to differentiation.

(2011) noted that the findings were apparently contradictory because the presence of an IDH1 mutation was thought to contribute to tumorigenesis; the authors suggested that IDH1 mutations may be involved in tumor initiation and not in tumor progression. 1, cytosolic C. a., Chang, J.
