Disease program
Recurrent thrombophlebitis

Vitamin K epoxide reductase complex subunit 1 shows approved-linked disease relevance led by Recurrent thrombophlebitis. 5 more disease programs remain visible in the same review block. 4 linked drugs remain visible in the same block.

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