I'm with Amy, I am also confused why it is necessary to have the two threads. I kept re-reading the first one and I'm not sure what I was missing or what is different?<img src="i/expressions/face-icon-small-confused.gif" border="0">So anyhow, just to be perfectly clear. <b>You need to take her to a CF Clinic to see what they think.</b> A GI or Pulmo would not be knowledgable enough to deal with diagnosing or not diagnosing a child that doesn't have two mutations - they may not even realize that you can have CF without the second mutation being found yet. Hence why I was discussing my son having no mutations but lots of symptoms and still having a CF diagnosis - he was diagnosed by the CF Clinic. Had we not gone to the CF Clinic we would still be wondering about his problems.So, yes I think you need to rule out CF (by going to a CF Center) and then if it is truly ruled out then you go on to figure out what is causing her problems.
