FOXO1
Overview
Mutations in the FOXO1 gene, which encodes a member of the forkhead family of transcription factors, play a significant role in diffuse large B-cell lymphoma (DLBCL). Mutations primarily occur in the first exon, with significant portions affecting the N-terminal region and the Forkhead DNA binding domain.1 These mutations are common in DLBCL, BL and, to a lesser extent, FL.2,3 FOXO1 mutations can contribute to resistance to certain therapies, such as anti-CD20-based immunotherapies, by repressing MS4A1 (CD20) expression.4
