A U.S. company planned to offer a test for embryos created through in vitro fertilization that screened the entire genome for DNA variants linked to cognitive ability, in order to help couples avoid having children with intellectual impairment. Many ethicists fear such multigene analyses could one day be used to screen embryos for desirable traits as well, such as tall stature or high IQ. For those disturbed by the prospect, a study reported last week at the annual meeting of the American Society of Human Genetics in Houston, Texas, may come as a relief: For now, the strategy would not work very well.
