| Disease ID | Source | Name | Description |
| 300807 | OMIM | Thrombophilia, X-linked, due to factor IX defect (THPH8) | A hemostatic disorder characterized by a tendency to thrombosis. The disease is caused by variants affecting the gene represented in this entry. |
| 301052 | OMIM | Warfarin sensitivity, X-linked (WARFS) | A condition characterized by sensitivity to warfarin, a drugs used as anti-coagulants for the prevention of thromboembolic diseases in subjects with deep vein thrombosis, atrial fibrillation, or mechanical heart valve replacement. Warfarin sensitive individuals develop bleeding complications when they are given warfarin within the therapeutic ranges. The disease is caused by variants affecting the gene represented in this entry. |
| 306900 | OMIM | Hemophilia B (HEMB) | An X-linked blood coagulation disorder characterized by a permanent tendency to hemorrhage, due to factor IX deficiency. It is phenotypically similar to hemophilia A, but patients present with fewer symptoms. Many patients are asymptomatic until the hemostatic system is stressed by surgery or trauma. The disease is caused by variants affecting the gene represented in this entry. |
