I just realized that I haven't yet posted by FISH results from the CVS. I'll post them now so to help future readers.
Our FISH results suggest that Trisomy 21, 18 and 13 are clear but the sex chromosome results were inconclusive. It was suggestive of a sex chromosome mosaicism. Approximately 45% of cells were XO and 55% of XY.
My Ob and the geneticist she has been speaking with suggest mosaic turners syndrome which has varying results depending on the amount of cells etc. They are almost always girls. I have spoken to the local genetic team who were tending to think it may be something else and that the baby is a boy because of the XY chromosomes. I am confused about this but I do trust my Ob as she has a lot of experience. Anyway the amnio Monday will tell us if the baby is affected or just the placental tissue so I still secretly have a little part of me hoping they will tell me it was all wrong but I am prepared as well as I can be for the worst.
Thanks so much for sharing your story with me Amyd, it gives me a little glimmer of hope x
