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. KLHL6 mutations lead to the loss of its function as part of a cullin-RING ubiquitin ligase complex. KLHL6 is considered a tumor suppressor gene in DLBCL with mutations tending to disrupt its interaction with cullin3, leading to the loss of its ligase activity.2
