TCGA Brain Lower Grade Glioma. Source data from GDAC Firehose. Previously known as TCGA Provisional. This dataset contains summary data visualizations and clinical data from a broad sampling of 530 carcinomas from 516 patients. The data was gathered as part of the Broad Institute of MIT and Harvard Firehose initiative, a cancer analysis pipeline. The clinical data includes mutation count, information...

Clinical data includes: Cancer Type, Number of Samples Per Patient, Mutation Count, Fraction Genome Altered Sample Type, Sex, Oncotree Code, Sample Collection Method, Somatic Status, Specimen Preservation Type. The plaintext components of the dataset can be...

Study Description from dbGaP: "The main goals of the GICC Study were: 1) to identify novel genetic risk variants for glioma, as well as validate variants implicated by previous genome-wide association studies of glioma; and 2) to explore biologically relevant gene-gene and gene-environment interactions in glioma susceptibility." Study Inclusion Criteria: "Diagnosis of histologically confirmed, supratentorial,...

Study Description from dbGaP: "We conducted a new independent GWAS of adult glioma using 1,856 cases and 4,955 controls from 14 cohort studies belonging to the Cohort Consortium, 3 case-control studies, and 1 population-based case only study. Cases were newly diagnosed glioma [ICDO-3 codes 9380-9480 or equivalent], and controls were cancer-free at the time of glioma diagnosis. We found evidence of...

Summary from GEO: "Diffuse gliomas represent the most prevalent class of primary brain tumor. Despite significant recent advances in the understanding of glioblastoma (WHO IV), its most malignant subtype, lower-grade (WHO II and III) glioma variants remain comparatively understudied, especially in light of their notably variable clinical behavior. To examine the foundations of this heterogeneity,...

Summary from GEO: "Glioma CIMP (G-CIMP) is a powerful determinant of tumor pathogenicity but the molecular cause of G-CIMP is a fundamental question that is unresolved. Here, we show that mutation of a single gene, isocitrate dehydrogenase 1 (IDH1), directly causes the G-CIMP in gliomas by remodeling the methylome." Overall design from GEO: "In this study 52 glioma clinic samples (36 CIMP+ and...
