With the DDF508, I knew there was varability, but I think if you have two of the Class III and IV mutations, CF usually is less severe, even down to the only symptom in adulthood being the absence of the Vas Deferences.....
Does anyone have two of these mutations and if so, what has your health been and current FEV1.
