Perfect! Here's your filtered view:

**[View TCGA Lower Grade Glioma — IDH1 & TP53 Mutant Samples (Summary)](https://www.cbioportal.org/study/summary?id=lgg_tcga_pan_can_atlas_2018#filterJson=%7B%22geneFilters%22%3A%5B%7B%22geneQueries%22%3A%5B%5B%7B%22hugoGeneSymbol%22%3A%22IDH1%22%7D%2C%7B%22hugoGeneSymbol%22%3A%22TP53%22%7D%5D%5D%2C%22molecularProfileIds%22%3A%5B%22lgg_tcga_pan_can_atlas_2018_mutations%22%5D%7D%5D%7D)**

This filters the **Brain Lower Grade Glioma (TCGA, PanCancer Atlas)** cohort (514 total samples) to show only samples carrying **mutations in both IDH1 and TP53**. The summary page displays interactive clinical and genomic charts for this filtered subset.
