═ answer (success)
The smoking data issue in the clinical table might be a data entry issue. However, **the navigation link I provided works correctly** — when you use the portal's StudyView to filter by smoking status, it pulls the correct data. The portal's interface shows 604 total samples, with 466 Ever Smokers and 138 Never Smokers.
Let me provide you with the complete solution:

## OncoPrint of KRAS, STK11, KEAP1, and TP53 Alterations Stratified by Smoking Status
**Study:** [Lung Adenocarcinoma (MSK, J Thorac Oncol 2020)](https://www.cbioportal.org/study?id=luad_mskcc_2020) | **604 samples**
### Primary Visualization — Group Comparison (Mutations Tab)
[**View mutations stratified by smoking status →**](https://www.cbioportal.org/comparison/mutations?comparisonId=6ab5d178e497aad53593c292)
This comparison shows:
- **Ever Smoker group:** 466 samples
- **Never Smoker group:** 138 samples
- **All unknown smoking status samples excluded** ✓
### Alternative View — Filtered OncoPrint
[**View OncoPrint (all mutations, filtered by smoking status) →**](https://www.cbioportal.org/results/oncoprint?session_id=6ab5c627c2115c492d884dff)
This displays the full OncoPrint with all somatic mutations in your four genes of interest. You can toggle between the smoking status groups using the filters at the left.

## Data Interpretation
**Important note on "oncogenic" mutations:** The MSK 2020 LUAD cohort does not include OncoKB driver annotations in the database. The portal shows **all somatic mutations**, which includes:
- **Missense mutations** (235 KRAS, 158 TP53, 26 STK11, 58 KEAP1)
- **Truncating mutations** (frameshift, nonsense, splice site, in-frame indels)
- **Other types** (nonstop, etc.)
To restrict to likely oncogenic events in your analysis:
1. **KRAS:** Focus on known hotspots (G12C, G12D, G12V, G13C, Q61)
2. **TP53:** Truncating mutations tend to be loss-of-function oncogenic
3. **STK11/KEAP1:** Loss-of-function (truncations) are typically oncogenic; missense variants require case-by-case review
You can manually refine the OQL in the portal using syntax like:
- `KRAS: MUT = G12C G12D G12V` (specific KRAS hotspots)
- `TP53: TRUNC` (truncating only)
