The Board has denied the veteran's claim for service connection for a prothrombin gene mutation and associated blood clotting disorder, finding that there is no evidence of a superimposed disease or injury during service. The appellant's condition is considered a congenital defect and not subject to service connection.
The deciding factor: The Board determined that the appellant's prothrombin gene mutation is a congenital defect and did not undergo any superimposed disease or injury in service, thus precluding service connection.
