Chen et al. IDH3 is one of three isocitrate dehydrogenase isozymes, the other two being IDH1 and IDH2, and encoded by one of five isocitrate dehydrogenase genes, which are IDH1, IDH2, IDH3A, IDH3B, and IDH3G. [PubMed: 4695153] Note: Addendum: Nature 465: 966 only, 2010. This pathway uses mitochondrial and cytosolic isoforms of NADP+/NADPH-dependent IDH1, and subsequent metabolism of glutamine-derived citrate provides both the AcCoA for lipid synthesis and the 4-carbon intermediates needed to produce the remaining citric acid cycle (CAC) metabolites and related macromolecular precursors. New Eng. The median survival was 3.8 years for patients with mutated IDH1, as compared to 1.1 years for patients with wildtype IDH1.

Similarly, an integrative clustering analysis by an international collaborative effort defined four CCA clusters – Fluke-Positive CCAs (Clusters 1/2) were enriched The isocitrate dehydrogenase (IDH) proteins are critical enzymes in the Krebs cycle, which is central to many biochemical pathways.

Tissue biopsies of late-stage bladder cancers also showed IDPC downregulation compared with early-stage bladder cancers. Sci. Somatic mutations in the IDH1 gene have been associated with several other forms of cancer, including brain tumors called gliomas and bone tumors known as chondrosarcomas. Like the genetic changes that cause CN-AML (described above), the IDH1 gene mutations found in these cancers are gain-of-function mutations. Personal Communication.

Instead, the altered enzyme takes on a new, abnormal function: the production of a compound called D-2-hydroxyglutarate. (2016) specifically demonstrated that loss of CTCF at a domain boundary permits a constitutive enhancer to interact aberrantly with the receptor tyrosine kinase gene PDGFRA (173490), a prominent glioma oncogene. What is a gene mutation and how do mutations occur? A, Campbell P, Presneau N, Flanagan AM. In total, 18 of 149 GBMs (12%) analyzed had alterations in IDH1. As in Maffucci syndrome, the IDH1 gene mutations that cause Ollier disease are somatic gain-of-function mutations and are thought to occur early in development, resulting in mosaicism. Mutation of the IDH1 gene was strongly correlated with a normal cytogenetic status; it was present in 13 of 80 cytogenetically normal samples (16%). The IDH1 gene provides instructions for making an enzyme called isocitrate dehydrogenase 1. The protein encoded by this gene is the NADP(+)-dependent isocitrate dehydrogenase found in the mitochondria. [PubMed: 9866202, related citations] It is characterized by multiple enchondromas, which are noncancerous (benign) growths of cartilage that develop in the bones, and red or purplish growths in the skin consisting of tangles of abnormal blood vessels (hemangiomas). The deduced protein shares 59% identity with yeast Idp3. The α-ketoglutarate is oxidized by reducing the NAD to NADH and releasing one molecule of CO2. It is unclear why IDH1 gene mutations have been found in only these few types of cancer. MedlinePlus Genetics provides information about Primary myelofibrosis.
