TET2 promoter methylation in low-grade diffuse gliomas lacking IDH1/2 mutations.

Abstract excerpt

BACKGROUND: Miscoding mutations of the TET2 gene, which encodes the α-ketoglutarate-dependent enzyme that catalyses the conversion of 5-methylcytosine to 5-hydroxymethylcytosine, thus producing DNA demethylation, have been detected in 10-25% of acute myeloid leukaemias lacking IDH1/2 mutations. Most low-grade diffuse gliomas carry IDH1/2 mutations (>85%), but molecular mechanisms of pathogenesis in those lacking...
