Description: This dataset contains summary data visualizations and clinical data from a broad sampling of 514 brain lower grade gliomas from 514 patients. The data was gathered as part of the PanCancer Atlas initiative, which aims to answer big, overarching questions about cancer by examining the full set of tumors characterized in the robust TCGA dataset. The clinical data includes mutation count, information about mutated genes, patient demographics, disease status, tumor typing, and chromosomal gain or loss. The data set also includes copy-number segment data downloadable as .seg files and viewable via the Integrative Genomics Viewer.

Access via cBioPortal
Access Restrictions: Free to All
Access Instructions: This cBioPortal for Cancer Genomics dataset is publicly available for viewing in tables or, for copy-number segments, via integrated IGV application. The data is also available for download in its entirety as a tarball or as individual TSV (tab separated value) or SEG files. Some features are only available by logging in with a Google or Microsoft account. These features include storing your virtual studies and groups which allows you to access your studies and groups from any computer, and to allow cBioPortal to remember your study view charts preferences for each study (i.e. order of the charts, type of charts and visibility). Login is optional and not required to access any of the other features of cBioPortal. Downloaded SEG files (tab-delimited segmented data text files that list loci and associated numeric values) can be viewed by downloading and installing the Integrative Genomics Viewer desktop application.
