KLHL6
Overview
KLHL6 mutations appear to be relatively common in DLBCL, FL and possibly BL.1 KLHL6 is one of a number of genes affected by aberrant somatic hypermutation in B-cell lymphomas, which complicates the interpretation of mutations at this locus.
Relevance tier by entity
| Entity | Tier | Description |
|---|---|---|
| BL | 2-a | aSHM target; Although recurrent, the relevance of mutations in BL is tenuous |
| DLBCL | 1-a | aSHM target and high-confidence DLBCL gene |
| FL | 1-a | aSHM target and high-confidence FL gene |
Mutation incidence in large patient cohorts (GAMBL reanalysis)
| Entity | source | frequency (%) |
