A cohort of 530 patient samples with low grade gliomas (LGG) and a cohort of 172 patient samples with GBM from The Cancer Genome Atlas (TCGA) RNA sequencing (RNAseq) database were analyzed for TMEM230 expression level (The Cancer Genome Atlas Research Network2) (Cancer Genome Atlas Research Network, Weinstein et al., 2013). This evidence concerns the gene TMEM230 and glioblastoma.
