Common question: Is it possible that Mckenna has CF?

Is it possible? Yes. Is it probable? No. The chances that Mckenna has CF are SLIM TO NONE. The first thing Mandi and I did when we decided we wanted to start a family, was getting Mandi tested for the CF gene. Mandi was screened for all known mutations (over 1600) and they concluded that Mandi was NOT a carrier of any known CF mutation. The chance that Mandi is a carrier of a single copy of any CF mutation is less than 1% (.0004% to be exact). Therefore, the chance that Mckenna would have CF is less than .000001%, or less than 1 out of 1,000,000. So, anything is possible, but it is not very likely. In other words, there's a greater chance that she has a host of other things going on than it would be that she has CF :)
