One Step Closer to Designer Babies

April 25, 2011

A new approach to testing the genes of early-stage fetuses could radically alter the experience of pregnancy and parenting. And we’d better start thinking about it now—before hype, fear, and the polarized politics of abortion distort the discussion. The technique being developed analyzes fetal DNA that is collected from women’s blood as early as five weeks into a pregnancy. So-called “noninvasive prenatal diagnosis,” or NIPD, may hit the market as a test for Down syndrome later this year. Soon after, refinements are likely that will allow identification of fetal genes at thousands of sites; two different research groups published papers claiming “proof in principle” of this prospect last December.
