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

As of 2026-09-13

Prothrombin shows approved-linked disease relevance led by Recurrent thrombophlebitis. 5 more disease programs remain visible in the same review block. 6 linked drugs keep the current disease frame grounded. Protein identity stays anchored to UniProt P00734. Start with Recurrent thrombophlebitis, then reuse UniProt P00734 as the stable protein anchor across project notes and exports.

Disease program
Recurrent thrombophlebitis

Prothrombin shows approved-linked disease relevance led by Recurrent thrombophlebitis. 5 more disease programs remain visible in the same review block. 6 linked drugs remain visible in the same block.

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