The invention relates to inhibition of wild-type and certain mutant forms of human histone methyltransferase EZH2, the catalytic subunit of the PRC2 complex which catalyzes the mono- through tri-methylation of lysine 27 on histone H3 (H3-K27). In one embodiment the inhibition is selective for the mutant form of the EZH2, such that trimethylation of H3-K27, which is associated with certain cancers, is inhibited. The methods can be used to treat cancers including follicular lymphoma and diffuse large B-cell lymphoma (DLBCL). Also provided are methods for identifying small molecule selective inhibitors of the mutant forms of EZH2 and also methods for determining responsiveness to an EZH2 inhibitor in a subject.

The invention is directed to a method of prognosing in an individual a transformation from follicular lymphoma to diffuse large B-cell lymphoma (DLBCL) by measuring changes and / or lack of changes in certain groups of related clonotypes, referred to herein as “clans,” in successive clonotype profiles of the individual. A clan may arise from a single lymphocyte progenitor that gives rise to many related lymphocyte progeny, each possessing and / or expressing a slightly different immunoglobulin receptor due to somatic mutation(s), such as base substitutions, inversions, related rearrangements resulting in common V(D)J gene segment usage, or the like. A higher likelihood of transformation from follicular lymphoma to DLBCL is correlated with the persistence of clans in successive clonotype profiles whose clonotype membership fails to undergo diversification over time.
