In theory, NO it should NOT be a problem. Anavar is anabolic steroid and will not effect your condition (again in theory). and I even know one very successful IFBB Fitness competitor with the same condition. However I would still consult your doctor before you use any "supplements".
As for general safety, Anavar is considered one of the safest steroids, altough nobody can give guarantees that you will not experience any side effects, like acne, hair growth (or hair loss), verilization.
Hope it helps.
