The Board found that the Veteran's diagnosed blood clot disorder, Leiden Factor V, is a congenital defect and thus not subject to service connection as it cannot be considered a disease or injury. The claim for service connection was denied.
The deciding factor: The evidence did not demonstrate that the Veteran's congenital defect of Leiden Factor V was subjected to a superimposed disease or injury during service which created additional disability, and therefore could not meet the criteria for direct service connection.
