My son had been diagnosed with Atypical CF - this isn't a label I have chose to put on him or have heard somewhere and I thought, hey let's call it Atypical or that I use because I am in denial and think Atypical sounds better. He was <b>diagnosed</b> by two different accredited CF clinics with <b>Atypical CF</b>. It's real, it's out there, it's a term they use nowadays.I think the problem lies in the fact that a diagnosis of CF is not as cut and dry as it used to be. Back before genetic testing you had to have clear cut common symptoms to be labeled CF. Now that they are doing newborn screening, prenatal carrier screening, etc it is throwing a lot more kids into the CF pool that may have never been part of it before. You are getting kids that have two mutations, but have no classic symptoms whatsoever and you also have kids that have one or no mutations and symptoms all over the place. I can see where older CFers would cringe at the thought of the words and worry that all the new mommies out there won't do treatments for their kiddos, but I would suggest that you ask your cf clinic doctors why and who they diagnose as Atypical CF because I would bet you your clinic gives out that diagnosis also - it's not as uncommon as you think. Now I am talking about an actual diagnosis of Atypical CF, not the people who chose to use that term to mean mild CF. I totally agree, there is no mild cf, only mild CF symptoms for the time beingOh, and the reason they call my son's CF Atypical CF is because they can't find any mutations, yet he has very high sweat tests, lung damage, GI issues and Failure to Thrive. He's on the CF registry, follows traditional CF treatments and see the CF clinic every three months.
