@Dell79:  How awful! It does seem like her reality is greater than 25%, but maybe it’s just bad luck. 🙁 I don’t know much about CF, but maybe there are some other genes associated with the disease that your sister and Brother-In-Law carry that haven’t yet been identified by science??

There is a lot of breast and ovarian cancer in my family, but my mom and aunts (who all had cancer at a young age) have tested negative for the BRAC genes. I went to a genetic counselor and they recommended I get yearly mammograms, ultrasounds, and MRIs. They said there is obviously a genetic link, they just haven’t found it yet.

That being said, I hope in your sister’s case it is just bad luck and that their luck turns around soon! My thoughts and prayers go out to your family.

The odds are for each pregnancy that the embryo will have cystic fibrosis.  Yeah it does seem like the odds are stacked against her but each seperate time is on it’s own.  It is possible that there are other genetic factors for cystic fibrosis, there is so much we still don’t know about the human genome.

I wish your sister luck with having a healthy baby.

Each individual fetus has a 1 in 4 chances of having CF. It’s not an overall average for all pregnancies.

This must be a terrible thing to go through. I couldn’t imagine keep getting pregnant and then aborting your child, health issues or not I can imagine this take an emotional toll on your sister. My cousin tested positive for the CF gene and they did do IVF and not have 4 beautiful healthy little girls. Hopefully she can find a way to work with insurance, even if it takes longer to get pregnant to work this out.

I’m so sorry for your sister.  Each time they conceive, the embryo has a 25% chance of having CF, so she’s just really unlucky that she has fallen in that 25% on the last 3 tries.  It really sounds like she’s been put through the wringer.  I really wish her luck on her next try to end up in the other 75%!!

How heartbreaking for your sister.  I hope their next pregnancy is CF free.

Wow – how heartbreaking.  It is one thing to know that each embryo has a separate 25% chance of having CF but it is a totally different thing (emotionally) to have to deal with the heartbreak 3 times in a row.
