Hi there 3boys, welcome too healing well!
I have never heard of a mosaic gene, or anything else that mimics the CF gene. CF symptoms do happen things like nasal polyps and such, but never heard of genes being mimicked. There are different mutations of CF though, and only a percentage of them can be tested for.
It is possible that the CF gene is wide spread between your family, it is found in every 1 in 25 people. A singular carrier gene can do no harm on its own, but if a second parent is a carrier, then there is a one in 4 chance that a child will have Cystic Fibrosis.
The guthrie heel prick test done at birth, isn't an exact measure. To my understanding it is used because it is the best possible thing to find CF and other illness at birth. However it doesn't always work. Someone please corect me on this if I am wrong.
On one of the other CF forums, there has been a recent post about
people who have known CF in the family. There are a suprisingly low amount, considering how "popular" the gene is. Here is that thread:
Polite request also: You don't have too do this, it's not against forum rules, but could I just make a slight mention that your post is incredibly hard too read. Being such a bright blue on a white background. I personally had too force myself too read through your post. However many other members if they have the problem with reading bright blue on white won't be able too. I know that dyslexics struggle with the colour combination also. I believe you are more likely too get a full range of responses, if you stick too black, or a mix of colours too break it up a bit. As I say you don't have too do this, I will still force myself too read posts no matter what the colour, so you are sill guarenteed a response. Thanks, Gem.
