Whole Chromosome View of Segmented CNV data
You can use Xena to view segmented copy number (CNV) data along a specific genomic region or an entire chromosome.
Co-deletions in Lower Grade Glioma
For each of the three subtypes of TCGA Lower Grade Glioma, you can see corresponding deletions in chromosome 1p (3rd column from the left) and chromosome 19q (4th column).
Deletions and Amplifications in Gliomas
Looking more broadly at Glioblastoma Multiforme (GBM) and Lower Grade Glioma (LGG) in TCGA (column A), we can see the same arm-level co-deletions in chr1p (column B) and chr19q (column C) primarily in LGG tumors. Columns D and E show us an amplification in EGFR and a deletion in PTEN, both of which are associated with GBM rather than LGG tumors.
