As of 2026-09-13

Receptor-type tyrosine-protein kinase FLT3 shows approved-linked disease relevance led by acute myeloid leukemia. 5 more disease programs remain visible in the same review block. 22 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P36888. Start with acute myeloid leukemia, then reuse UniProt P36888 as the stable protein anchor across project notes and exports.

Disease program
acute myeloid leukemia

Receptor-type tyrosine-protein kinase FLT3 shows approved-linked disease relevance led by acute myeloid leukemia. 5 more disease programs remain visible in the same review block. 22 linked drugs remain visible in the same block.

Start review with acute myeloid leukemia because it currently carries approved-linked support. Linked drugs include 4SC-203, AKN-028, AMG553, CRENOLANIB. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
