If we have parents or perspective parents
who have a genetic concern, and that might be that they are carriers of a problem they
don’t want to pass on that increases risk, for example BRAC1 or BRAC2, which isn’t necessarily
going to result in a disease but causes a lifetime of concern for the person who has
it, or there might be a know genetic disease. There might be cystic fibrosis or sickle cell,
hemophilia, lots of different genetic diseases that the parent might have or they might know
they carry the gene for it. So if we have someone with genetic concerns what we can
do is do an In-Vitro fertilization procedure where we have embryos formed outside the body.
And then we can biopsy the early placenta, it’s called the trophoblast, but anyway we
can biopsy a little bit of the cellular material that’s not going to become the baby, and we
can do a genetic test on that and we can find out if this embryo is going to carry that
gene, if they’re going to have a disease or not and there that’s a way to avoid transmitting
what could be a lethal or devastating gene defect to the next generation. So the genetic
problem stops here and doesn’t get carried on any further. Often that couple would not
have infertility; they would just be worried about having a family because of their genetic
concerns or their family history.
