I have Russell-Silver syndrome (RSS) and my boyfriend has cystic fibrosis. I recently found out that both are caused by mutations of chromosome 7. Does that mean that I could be a carrier of cystic fibrosis (CF)? See answer
My child is 11 years-old and has many of the symptoms of cystic fibrosis. She'll be undergoing testing next week. How common is it to be diagnosed with cystic fibrosis this late in life? See answer
Are carriers of cystic fibrosis at a higher risk for other health conditions? See answer
We have been told that my newborn grandson has been classified as a carrier for cystic fibrosis. I know that if both parents have the defective gene, the child has a 25 percent chance of actually getting CF, and a 50 percent chance of being a carrier. My question is, can the child be a carrier if only one parent has the defective gene?
Thank you. See answer
What are the current genetic tests for cystic fibrosis? How much do they cost? See answer

Could you please send any and all information on Cystic Fibrosis. One of the staff members has a child with CF and stated the child is not suppose to be in the same classroom with another child with CF. I would like to know why that is? I assume it is related to the altered immunity state. How does this work? What do they do to address this problem? See answer
