As of 2026-09-14

Cyclin-dependent kinase 2 shows late clinical disease relevance led by chronic lymphocytic leukemia. 5 more disease programs remain visible in the same review block. 4 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P24941. Start with chronic lymphocytic leukemia, then reuse UniProt P24941 as the stable protein anchor across project notes and exports.

chronic lymphocytic leukemia

Cyclin-dependent kinase 2 shows late clinical disease relevance led by chronic lymphocytic leukemia. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

Start review with chronic lymphocytic leukemia because it currently carries late clinical support. Linked drugs include ALVOCIDIB, BMS-387032, DINACICLIB, ZOTIRACICLIB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
