My 2 month old has one of the F508 mutated genes and her sweat test came out positive. They did another blood work to check for the other cell for the next 150 or so other most common cells and nothing came up. So I asked them to further the tests so they are going to but they said she is 1 in 10% of all cf patients to have an odd ball cell.Any suggestions would be good. They say her lungs are clear but she has a cough at times and they say it is reflux and they are watching to determine if she has asthma. Astha runs in the family. My husband and I never new we were carriers. There has never been a case of cf known in the family on either side. Now that they cann't find the other cell only one of our families will know if they are carriers. How odd does this sound? Is this common to not know of anyone being a carrier and all of a sudden she is possitive and she has 1 cell that is odd and hasn't found it yet? Please let me know. She has been gaining weight on her own wonderful. They did do a stool sample to check and they found a little protein so they put her on Creon5. But before this she has gained all her weight on her own and has grown 2 and a half inches in 2 months and gained over 3 pounds.
