KMT2A and mantle cell lymphoma: Ferrero et al. (2019) recently published the poor prognostic role of MLL (KMT2D) in MCL. The interaction of CDC20 and MLL (KMT2D) in MCL requires further study. CDC20 can predict the overall survival in Diffuse large B-cell lymphoma based on The Cancer Genome Atlas data (Sun et al., 2019a).
