NCAPG and central nervous system cancer: In addition, comparisons of NCAPG expression in gliomas with and without co-deletion of chromosomes 1p and 19q and in gliomas with wild-type and mutant IDH showed that NCAPG expression was higher in gliomas without than with chromosome 1p/19q co-deletions and was significantly higher in IDH-wild type than in IDH mutant gliomas (Figures 1C, D).
