As of 2026-09-13Fibroblast growth factor receptor 4 shows clinical signal disease relevance led by cancer. 1 more disease program remain visible in the same review block. 1 linked drug keeps the current disease frame grounded. Protein identity stays anchored to UniProt P22455. Start with cancer, then reuse UniProt P22455 as the stable protein anchor across project notes and exports.
Fibroblast growth factor receptor 4 shows clinical signal disease relevance led by cancer. 1 more disease program remain visible in the same review block. 1 linked drug remains visible in the same block.
Start review with cancer because it currently carries clinical signal support. Linked drugs include FGF401. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
