<b>CFHockeyMom</b> answered this very very nicely. I would think that with two CF genes, positive sweat test and classic CF symptoms you can pretty much rest assured that a CF diagnosis and treatment is the correct course of action.
<b>Sakem </b>does have a valid point about the two genes having to be on different strands of the DNA -- however with all the additional information about your son I cannot imagine this would be the case with him -- either they are on two different strands or like <b>peanut07</b> has said...perhaps they have missed a second gene that would be found if complete deletion and duplicate testing is done.
If it were me, I'd clarify with the geneticist but I wouldn't really expect to come out of this without a CF diagnosis... in fact without it might only do more harm than good if it caused him to not get the best monitoring and treatments available. Again, my advise might be different had you not described some very classic CF symptoms.
