Somatic mutations have been identified recently that codify for isocitrate dehydrogenase (IDH). These genes codify key metabolic enzymes, which convert isocitrate into α-ketoglutarate (α-KG).15-16From which IDH1 and IDH2 genes presenta high frequency of mutations in AML and other types of tumors. IDH mutations affect mainly active site residues (for example, IDH1 R132, IDH2 R140 or IDH2 R172), resulting in the normal enzymatic function loss abnormally converting α-KG to 2-hydroxiglutarate (2-HG).
