Went to see the geneticist at Kings yesterday and was expecting them to tell me that there was no more likelihood of this baby having the same condition as dd as any other baby, as this is what we have always been led to believe (and i have found in my own research). However, I was told yesterday that the 'problem' would have been with my egg. It is possible that this was the only flawed egg or it is possible that I have more affected eggs. That means there is a very real chance that this baby may have the same condition. Not a high chance but a real one.
There is only one known incidence of recurrence in the same family, this is out of about 800 cases of the condition known worldwide. Which doesn't give a great statistical chance. But then to be honest the sample pool is so small it is almost meaningless. Also tbh when your dd has a condition that she had about a 1 in 4 million chance of having you kind of lose faith in statistics.
If this baby does have the same condition as dd there are some quite obvious brain abnormalities that they should be able to pick up on a scan at about 21 weeks. I do at least feel that we are in the best possible hands at Kings. They have said that if there is anything they are at all unsure about then I can have an in-utero MRI scan.
I am scared though. I wasn't really until now. I had vague worries about this baby having SN, which I think is only natural. But now it seems very real that this baby could have the same condition as dd and tbh I would find that very very hard to deal with.
I know that there is nothing I can do and I just have to wait for the scan and hopefully everything will be fine. It has been a bit of a shock though.
