well last night the consultant said they are looking at chromosome breakage syndrome, of which there are 4 different genetic conditions, one of which is Fanconi's. This must mean that both Andy and Debbie are carriers, and would therefore have a 50% chance of having a child that is a carrier, and a 25% chance of having a child with the condition. So 1 child in every 4 they have by law of average?
I am only familiar with the Fanconis anaemia of the 4, and life epectancy is usually 25 years? on average.
so a bone marrow transplant is what Sarah would need, in 'real life' an unrelated donor would be sought from the national register, as 9 months is a long wait for Sarah. It wont kill her, but the lack of blood cells she has now would be nasty to live with for that long, especially as at the end of a pregnancy the new child could be affected too anyway?
