We got the call today with the amnio results, and everything is normal! There are no signs of Trisomy 15, mosaic or otherwise. From a big picture perspective, this is good news. We still have plenty to worry about, but this is one hurdle along the way that we can say we have successfully cleared.
Now we wait until Friday for our next ultrasound to see how things look in there. And we continue to wait for our other test results.
The CGH analysis should be complete in the next week or so. The genetic counselor tried to rush those through, but that didn't work out. They have to let the cells grow and divide for so long before they can figure out what is going on there, so that takes longer than the amnio. The CGH is looking for any additions or deletions to the baby's chromosomes. If there are none, then that will be another hurdle cleared. While the CGH may not be able to tell us what is causing the cystic hygromas, it will at least help us eliminate what is not causing them.
There is still a chance that we are looking at a uniparental disomy- where the baby has 2 chromosome 15's from one parent or the other. But, according to the genetic counselor, the odds of that are so very slim that they will do that test once they have completed the other and ruled other things out.
Even if all of the testing continues to come back normal, we still have to worry about the cystic hygroma and the hydrops. But, at this point, we will take every small victory along the way that we can get. And every good test result we get along the way increases the baby's chances of being healthy and compatible with life if we do overcome the cystic hygroma and hydrops.
Please keep praying for us and for this baby. And thank you all so much for all you have done for us so far. We will update again on Friday after our appointment.
