This article was just published today, it states the following:
Spina bifida affects 1 in every 1,500 babies each year while CDH occurs in 1 of every 2,500. In the U.S., $230 million each year is spent due to CDH4. According to the Centers for Disease Control (CDC), $636,000 is spent for each baby born with spina bifida during their lifetime5. This is only a small fraction of the costs associated with the various diseases children can be born with. If the possibilities for stem and gene therapy come to fruition as many scientists believe they will, these costs can be reduced for both the families affected as well as the government.
