	I checked this out in Moore, The Developing Human (Clinical
Embryology) and they don't seem to mention this number. However, you
may want to extrapolate from these numbers:

	Malformations are observed in 2.7% of newborn infants.
	Congenital malformations are detected in additional 3% during
infancy.
	Not all of these are serious, however.

	The 1 in 4 figure may come from including pregnancies with
complications and elective abortions, but the actual figure is probably
closer to 5%, not 25%. If I see more on the subject that contradicts this,
I'll post it.
