The Board denied service connection for thrombocytosis as the evidence did not establish a relationship to service or a service-connected disability.
The deciding factor: The VA examiner found that the Veteran's thrombocytosis is less likely related to an event in service and explained that the negative JAK2 mutation does not disprove its etiology.
