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

As of 2026-09-14

Thromboxane-A synthase shows approved-linked disease relevance led by Recurrent thrombophlebitis. 2 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 P24557. Start with Recurrent thrombophlebitis, then reuse UniProt P24557 as the stable protein anchor across project notes and exports.

Recurrent thrombophlebitis

Thromboxane-A synthase shows approved-linked disease relevance led by Recurrent thrombophlebitis. 2 more disease programs remain visible in the same review block. 1 linked drug remains visible in the same block.

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