Genetic screening before pregnancy

A science blog I follow has a post about a company, one of several, that offers genetic testing to people thinking of having babies together to see if they carry any genes likely to do bad stuff to the kid if both parents have copies of them. Potential parents who both turn out to have such a gene can use in vitro fertilization with genetic screening of the embryos pre-implantation, to make sure the kid didn't get two copies of the gene.

Without knowing anything about the individual companies involved, this seems to me to be just the right way to do it, and I wish all of them well.

The blog post also points to an excellent NY Times article about the issue.
