Cystic Fibrosis Genetics and More - 23andMe

Let's Talk About Cystic Fibrosis #

Cystic fibrosis, huh? Sounds like a fancy term you’d hear in an ancient royal court, but it’s actually a rare genetic disorder that can really mess with your lungs and digestive system. Folks with this condition have two sneaky variants in their CFTR gene. If you're just hanging out with one variant, you’re labeled a "carrier," and while you might feel fine, you could still pass that genetic lottery ticket to your kids.


What Causes Cystic Fibrosis? #

So, what stirs up this whole cystic fibrosis situation? It all boils down to those pesky variants in the CFTR gene. This gene is responsible for creating a protein that keeps the salt and water balance in check for certain organs. When the CFTR gene gets a little quirky, the result is thick, gooey mucus that can create a backstage pass for lung infections and wreak havoc on digestion. So, if you fancy a normal respiratory experience, cystic fibrosis is definitely not on the guest list!
