Combined with hTERT promoter mutations, the presence of CIC and FUBP1 mutations and oligodendroglial histopathological features and the absence of ATRX and TP53 mutations may more strongly indicate whether a tumor is 1p19q codeleted as seen in the many hTERT promoter mutated, 1p19q codeleted patients of this study.23 This “rule” holds in the two other hTERT mutated samples. Here, TP53 is linked to neoplasm.
