50%: Your chance of having your mother's mutation is 50% and you could test now that you are sexually mature. You only need to test for that particular mutation (single site analysis) unless there is suspicious family history in your dad's side too or you are of eastern europe jewish ethnicity. One of the families i follow has a different mutation from each side, so it can happen. Best to you.
