Functional assessment of genetic variants in thrombomodulin detected in patients with bleeding and thrombosis

Thrombomodulin (TM) expressed on endothelial cells regulates coagulation. Specific nonsense variants in the TM gene, THBD, result in high soluble TM levels causing rare bleeding disorder. In contrast, though THBD variants have been associated with venous thromboembolism, this association remains controversial. A multigene panel was used to diagnose 601 patients with inherited bleeding or thrombotic disorders. This resulted in the identification of 8 THBD variants for six patients with …
