What is the official name of the IDH1 gene?
The official name of this gene is “isocitrate dehydrogenase 1 (NADP+), soluble.”
IDH1 is the gene's official symbol. The IDH1 gene is also known by other names, listed below.

What is the normal function of the IDH1 gene?
The IDH1 gene provides instructions for making an enzyme called isocitrate dehydrogenase 1. This enzyme is primarily found in the fluid-filled space inside cells (the cytoplasm). It is also found in cellular structures called peroxisomes, which are small sacs within cells that process many types of molecules. In both the cytoplasm and in peroxisomes, isocitrate dehydrogenase 1 converts a compound called isocitrate to another compound called 2-ketoglutarate. This reaction also produces a molecule called NADPH, which is necessary for many cellular processes. The NADPH produced from isocitrate dehydrogenase 1 is involved in the breakdown of fats for energy, and it also protects cells from potentially harmful molecules called reactive oxygen species.
How are changes in the IDH1 gene related to health conditions?
Genetics Home Reference provides information about primary myelofibrosis, which is also associated with changes in the IDH1 gene.
Where is the IDH1 gene located?
Cytogenetic Location: 2q33.3
Molecular Location on chromosome 2: base pairs 208,236,226 to 208,255,142
The IDH1 gene is located on the long (q) arm of chromosome 2 at position 33.3.
More precisely, the IDH1 gene is located from base pair 208,236,226 to base pair 208,255,142 on chromosome 2.
