Structured disease, protein, and project context should read before the lower-level identity rail.

As of 2026-09-13

CD74-ROS1 shows approved-linked disease relevance led by cancer. 3 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 P04233. Start with cancer, then reuse UniProt P04233 as the stable protein anchor across project notes and exports.

CD74-ROS1 shows approved-linked disease relevance led by cancer. 3 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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