In mantle cell lymphoma, EZH2 expression is associated with inferior OS and EZH2 expression shows a weak correlation with other PRC2 complex molecules, but no correlation with H3K27me3 expression, or loss of major histocompatibility complex (MHC) I/II (Martinez-Baquero et al., 2021). Here, EZH2 is linked to mantle cell lymphoma.
