═ answer (success)
I've set this up in **Brain Lower Grade Glioma (TCGA, PanCancer Atlas)** — 514 samples total. (This is the PanCancer Atlas cohort; there's also an older Firehose Legacy version, `lgg_tcga`, if you'd prefer that one instead.)

Two views, both filtered to **TP53 mutant OR EGFR amplified**:

**[Study View — filtered cohort overview](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%22TP53%22%7D%2C%7B%22alterations%22%3A%5B%22AMP%22%5D%2C%22hugoGeneSymbol%22%3A%22EGFR%22%7D%5D%5D%2C%22molecularProfileIds%22%3A%5B%22lgg_tcga_pan_can_atlas_2018_gistic%22%2C%22lgg_tcga_pan_can_atlas_2018_mutations%22%5D%7D%5D%7D)**
Shows clinical/genomic chart summaries restricted to samples matching either alteration. Click into any chart to further explore, or check the sample count at the top of the page.

**[OncoPrint — TP53 mutations & EGFR amplification](https://www.cbioportal.org/results/oncoprint?cancer_study_list=lgg_tcga_pan_can_atlas_2018&gene_list=TP53%3A+MUT%0AEGFR%3A+AMP&case_set_id=lgg_tcga_pan_can_atlas_2018_all)**
Visual per-sample alteration summary across the whole cohort, showing exactly which samples carry TP53 mutations vs. EGFR amplifications (or both).

Let me know if you'd like the exact sample count/list pulled directly, or if you'd like this run on the Firehose Legacy version instead.
