In conclusion, by comparing regional constituents of pathological subsets, incidences of 1p/19q co-deletion and IDH1/2 mutation in Chinese patients with gliomas, preferential distribution of tumor subsets, 1p/19q co-deletion and IDH1/2 mutation was confirmed in certain brain regions, implying their distinctiveness in tumor genesis and predictive value for prognosis in Chinese patient populations. This evidence concerns the gene IDH1 and glioma.
