Frequent gains and deletions; gains HDAC7A on chromosome 12 predominantly in GCB-DLBCL, losses of BACH2 and CASP8AP2 on chromosome 6 predominantly in ABC-DLBCL; Potential tumor suppressor genes: CASP3, IL5RA ARID1B, ROBO2 and MRS1; Potential oncogenes: KLHL6, IL31 and LRP1. This evidence concerns the gene IL5RA and diffuse large B-cell lymphoma.
