This link opens the **Brain Lower Grade Glioma (TCGA, PanCancer Atlas)** cohort with a pre-applied filter showing **514 samples**, restricted to those with:
- **TP53 mutations** (any type), OR
- **EGFR amplifications** (AMP)

The page will display charts showing the number of matching samples and their clinical characteristics. You can explore individual samples, download the filtered cohort, or switch to the OncoPrint view for a detailed genomic landscape visualization.
