FOXP1 is overexpressed in diffuse large B-cell lymphoma (DLBCL) and mucosa-associated lymphoid tissue (MALT) lymphoma through a recurrent chromosomal translocation T (3; 14) (p14.1; q32) involving IGH and FOXP1, which is associated with poor prognosis [11,12,13,14,15]. This evidence concerns the gene FOXP1 and diffuse large B-cell lymphoma.
