Hi I have a 9 month old daughter who was diagnosed when she was 20 days old. We recently spent two weeks in the hospital due to a lung infection still unsure of what is going to work on getting rid of this cough she has had forever. We are trying a few things right now so I hope they work. I was wondering about the delta F508, you mentioned does she have two copies or one? What does that mean and what is the difference? Does this mean the disease is more server with two or different parts of the body is affected with two? If you have any answer that would be terrific. Have a nice evening thank you, Jazzy
