Trisomy 18

I found out at a routine check-up with the midwife that the baby did not have a heartbeat. I was 18wks+4 days. An ultra sound confirmed the baby had died. I delivered him on 12 sept 05. The results of the chromosomes from our baby have shown a male karyotype with an extra chromosome no.18. I have 4 boys from my first marriage. This was to be my new partner's first baby, and our first together. We are due back to see our consultant obstetrician on 7 nov 05 and as it's only 15 oct. Our main question is can we have a normal pregnancy or is there a risk that 'edwards syndrome' will happen to us again.

With thanks,
Diane

Dear Diane,

I am so sorry to hear about the loss of your son.

Trisomy 18 is similar to Down's Syndrome (trisomy 21), but more severe. Babies born with trisomy 18 rarely survive even a few days after birth.

Like Down's Syndrome, the risk of trisomy 18 increases as the age of the mother increases. If you have already had one child with a trisomy, the risk of another is about 1%. The risk may be even higher depending on your age. Of course, this means that the chances of having a normal baby is still quite high.

Sincerely,
Amy
