FDA weighs risks of 3-person embryo fertilization
Federal health regulators will consider this week whether to green light a provocative new fertilization technique that could eventually create babies from the DNA of three people, with the goal of preventing mothers from passing on debilitating genetic diseases to their children.
The Food and Drug Administration has framed its two-day meeting as a "scientific, technologic and clinical" discussion about how to test the approach in humans. But the technique itself raises a number of ethical questions, including whether the government should sanction the creation of genetically-modified humans.
The FDA panel will hear from several prominent critics who oppose any human testing of the approach, arguing that it could be a slippery slope toward "designer babies," - in which parents customize traits like eye color, height and intelligence.
