KRAS
Overview
KRAS mutations are rare but occur in some cases of DLBCL.1 These often affect the most common KRAS hotspot sites that are mutated in other solid cancers (G12 and G13). ## History
Relevance tier by entity
| Entity | Tier | Description |
|---|---|---|
 |
1 | high-confidence DLBCL gene |
Mutation incidence in large patient cohorts (GAMBL reanalysis)
| Entity | source | frequency (%) |
|---|---|---|
| DLBCL | GAMBL genomes | 1.91 |
| DLBCL | Schmitz cohort | 3.62 |
| DLBCL | Reddy cohort | 1.70 |
| DLBCL | Chapuy cohort | 2.56 |
Mutation pattern and selective pressure estimates
| Entity | aSHM | Significant selection | dN/dS (missense) | dN/dS (nonsense) |
