There must be some previous study on this. If I remember right, Dr. New said if you are a carrier you will exhibit some CAH symptoms since the good gene won't neccesarily take over entirely. Just like salt wasting verses non salt wasting, the carrier should be somewhere on a CAH spectrum. Can't say for my husband, but for me the biggest symptom is salt craving. Just like my daughter I salt everything big time (with normal blood pressure).
