Solid state high resolution (HR) magic angle spinning (MAS) NMR methods were used to identify the spectroscopic finger print of 2HG in brain tumor tissues to confirm that 2HG is the metabolite marker of IDH mutations. The metabolite profiles of gliomas with and without IDH mutations are investigated quantitatively. The results confirmed that 2HG is a highly specific metabolite marker of IDH mutations in gliomas. In addition, HRMAS NMR analysis provided quantitative metabolite analysis that revealed the altered metabolite profile in tumors bearing with IDH mutations
