Overview

FBXW7 mutations are found in a range of lymphoid malignancies, including B-cell lymphomas. These mutations often include missense mutations, deletions, frameshift mutations and splice-site mutations. Overall, these mutations are relatively rare in DLBCL and occur more frequently in other solid tumors as well as T-cell acute lymphocytic leukemia.1 The most commonly observed mutations in those cancers are the hot spots R465 and R479.1 In leukemias, FBXW7 mutations enhance the activity of leukemia-initiating cells by stabilizing oncogenic MYC.2 Whether they have this role in DLBCL remains to be determined.
