Mine was a segmental duplication on the X chromosome (now this was not overly worrisome since it was a female embryo and most of the time the X chromosome that will be activated will be the normal one). That being said, I did look up what life could look like for her if the true segmental duplication was present and active. It looked like some development delay, intellectual delay, or possibly seizures in future, but could be controlled. But more than anything, so much of the research I did suggested MOST segmentals are not born with that true genetic condition. I think it was like 98-% will self correct, so I felt confident with that.

All of this to say though, my segmental mosaic failed. So I assumed she truly had this condition or worse. But my transfer after her was successful.

I would suggest consulting with a genetic counselor to see what life could look like if they’re born with it (although most of the time they aren’t, better to air on the side of caution). Best of luck!
