Overview
KLHL14 (Kelch-like family member 14) is a gene that has been identified as playing a role in B-cell lymphomas, particularly diffuse large B-cell lymphoma (DLBCL).1 KLHL14 has been identified as a recurrent target of somatic mutations in ABC DLBCLs. These mutations are a feature of the MCD genetic subgroup of DLBCL. The gene encodes a protein involved in the ubiquitin-proteasome system, and its inactivation leads to increased cell proliferation and survival, suggesting its role as a tumor suppressor.2 KLHL14 loss has been shown to BCR-dependent NF-κB activation and cell survival in DLBCL.2 This gene has some mutation hotspots but the patter of mutation overall is consistent with its role as a tumor suppressor gene.
Experimental Evidence
Driver mutations affecting this gene in DLBCL have been experimentally demonstrated to cause a reduction or loss of function (LOF).3
