As of 2026-09-14

Histone-lysine N-methyltransferase EZH2 shows approved-linked disease relevance led by follicular lymphoma. 5 more disease programs remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt Q15910. Start with follicular lymphoma, then reuse UniProt Q15910 as the stable protein anchor across project notes and exports.

Disease program
follicular lymphoma

Histone-lysine N-methyltransferase EZH2 shows approved-linked disease relevance led by follicular lymphoma. 5 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

Start review with follicular lymphoma because it currently carries approved-linked support. Linked drugs include TAZEMETOSTAT HYDROBROMIDE. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
