Prefer one of these safer approaches: - Use a shipped `cancer_study_query_preferences` cohort such as `pan_cancer_tcga` or `all_studies_non_redundant`. - Restrict to one named study. - Aggregate by `patient_unique_id` when the biological question is patient prevalence. ## STOP rule: a frequency above 100% means your query is wrong If your query returns a frequency over 100%, **do not try to debug or explain the data inconsistency to the user**. The cause is always one of these query bugs: - Summing mutation events instead of `COUNT(DISTINCT sample_unique_id)` for the numerator - Using a study-wide sample count as the denominator instead of the gene-specific profiled count - Cross-study aggregation where the same biological sample appears under multiple `sample_unique_id` values (e.g., MSK-IMPACT and MSK-CHORD share patients) - **Joining the profiled CTE through `gene_panel` / `gene_panel_list` without a WES branch.** `gene_panel_id = 'WES'` is *not* a row in … (35166 more chars) ▶ get_studyviewfilter_options { "studyId":

of genomic alteration rates across Ever Smoker (466) vs Never Smoker (138)."}} ═ answer (success) Perfect! I've created your OncoPrint stratified by smoking status. Here's what I've set up: ## OncoPrint Visualization **[View OncoPrint with Smoking Status Track](https://www.cbioportal.org/results/oncoprint?session_id=6ab5d177c2115c492d884e25&clinicallist=SMOKING_HISTORY)** ### Study Details - **Cohort:** Lung Adenocarcinoma (MSK, J Thorac Oncol 2020) - **Sample size:** 604 samples (466 ever smokers, 138 never smokers) - **Genes queried:** KRAS, STK11, KEAP1, TP53 - **Alteration filter:** Oncogenic somatic mutations only - KRAS: Missense mutations (236 samples) - STK11: Truncating mutations—nonsense, frameshift, splice site (92 samples) - KEAP1: Truncating mutations (72 samples) - TP53: Truncating mutations (213 samples) **Clinical track:** Smoking history is displayed below the genomic alterations so you can visually correlate each gene's alteration pattern with smoking exposure. --- ## Group Comparison (Ever Smoker vs Never Smoker) **[Compare Alterations by Smoking Status](https://www.cbioportal.org/comparison/alterations?comparisonId=6ab5d178e497aad53593c292)** This comparison tab will show: - Mutation frequency for each gene in ever smokers (466) vs never smokers (138) - Statistical tests (Fisher's exact, if applicable) - Co-alteration patterns between groups --- ### Notes - **Unknown smoking status excluded:** The filter restricts to samples with explicitly recorded "Ever Smoker" or "Never Smoker" status, removing 0 samples with unknown status in this cohort. - **Oncogenic definition:** Truncating mutations (frameshift, nonsense, splice-site) and KRAS missense variants are typically considered oncogenic for these genes in lung adenocarcinoma. This is a conservative selection; if you want to include other alterations (e.g., amplifications, or specific missense variants), you can modify the query in the cBioPortal interface. - **Driver annotations:** This dataset does not carry external OncoKB-annotated driver status in cBioPortal, so the alteration type is your primary filter for oncogenicity.
