IDH1 and central nervous system cancer: To determine whether this event might be recurrent in gliomas, and given multiple genomic alterations detected in this tumor closely resemble those found in adult low-grade gliomas (ALGGs) (mutations in IDH1, TP53 and ATRX) [10], we investigated the frequency of NAB2-STAT6 fusions in The Cancer Genome Atlas (TCGA) low-grade glioma database (http://cancergenome.nih.gov/).
