Hi, I haven't been on this board for a long time...our daughter (7w/CF) has this mutation 1898+1G<A, her lungs are fine, she has massive sinus problems and gastro issues/GERD when she deosn't poop she looks lile Santa sometimes....poop is very smelly, mushy, floaters, huge. She has always been underweight, at 5 to 15 percent group. Her sweat tests have been at 28 (CF clinic), one time at 100 at a non-CF clinic. She is going to get the 900 mutation test done...they said if another mutation doesn't show up, then this 1898 mutation could be it,.....they said it was rare.....they said overall she looks good but could be doing better, she is not at her best.She is not on emzymes yet, began inhaler, previcidd, zirtec and atarax for sinus, and nasonex plus daily sinus flushing, on Miralax to help go poop everyday. She has a aide to watch her at school, they do nothing else but watch.Her school district refuses to follow docs orders to document/chart her stools, he needs to how as to make adjustments in her meds.....They said they won't do more then 1 day a week!!!...Anybody have this school problem, what was your remedy w/ the school and anybody have this mutation??? What are your symthoms?? Thanks so much!!!
