Welcome to the site! I know it is a hard time right now....the first couple of years were really tough on us. We have adjusted to all the treatments, meds, etc...but it is still hard.
Our daughter has the same mutations as yours. I can tell you the classifications. There are 5 classes of genes...1 being the most severe to 5 being asymptomatic. 1717-1GA is a class 1, DF508 is a class 2. Remember that no 2 CF cases are exactly alike. We have 41 year old's and 7 year olds' with the same mutations on the site....with totally different cases.
Hang in there...you have found the source that will help you more than anywhere else!<img src="i/expressions/face-icon-small-smile.gif" border="0">
