Ethics Questions Arise as Genetic Testing of Embryos Increases; New York Times, 2/3/14

Gina Kolata, New York Times; Ethics Questions Arise as Genetic Testing of Embryos Increases:
"Genetic testing of embryos has been around for more than a decade, but use of the procedure has soared in recent years as methods have improved and more disease-causing genes have been discovered. The in vitro fertilization and testing are expensive — typically about $20,000 — but they make it possible for couples to ensure that their children will not inherit a faulty gene and to avoid the difficult choice of whether to abort a pregnancy if testing of a fetus detects a genetic problem.
But the procedure also raises unsettling ethical questions that trouble advocates for the disabled and have left some doctors struggling with what they should tell their patients...
Preimplantation diagnosis often goes unmentioned by doctors. In a recent national survey, Dr. Robert Klitzman, a professor of clinical psychiatry and bioethicist at Columbia University, found that most internists were unsure about whether they would suggest the method to couples with genes for diseases like cystic fibrosis or breast cancer...
“In the medical community, the lack of knowledge about P.G.D. is a serious concern,” said Dr. P. Murali Doraiswamy, a dementia researcher at Duke University Medical Center and an author of the new paper, referring to preimplantation genetic diagnosis. In his area — brain disorders — he adds, there are no guidelines about using the method, even though there are hundreds of inherited neurological conditions. Ms. Kalinsky, a nurse, and her husband, a doctor, only learned about the testing from a genetic counselor.
Ethicists are divided about use of the method."
