As of 2026-09-13

Cystic fibrosis transmembrane conductance regulator shows approved-linked disease relevance led by cystic fibrosis. 5 more disease programs remain visible in the same review block. 11 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P13569. Start with cystic fibrosis, then reuse UniProt P13569 as the stable protein anchor across project notes and exports.

Cystic fibrosis transmembrane conductance regulator shows approved-linked disease relevance led by cystic fibrosis. 5 more disease programs remain visible in the same review block. 11 linked drugs remain visible in the same block.

Start review with cystic fibrosis because it currently carries approved-linked support. Linked drugs include BAMOCAFTOR, DEUTIVACAFTOR, ELEXACAFTOR, GALICAFTOR. This disease block keeps the Open Targets-ready contract explicit while current evidence comes from ChEMBL mechanism and indication mappings.
