Carrier screening, embryo screening and prenatal testing are credited

Hot-button issues: Abortion, embryo destruction and eugenics

By Marilynn Marchione, AP/USA Today:

An investigation by the Associated Press concludes that some inherited diseases are declining and others have nearly disappeared, a trend that is credited to the increased use of genetic testing either before or after conception. A study in California found a reduction of almost 50 percent in the number of babies born with the most severe form of cystic fibrosis because many parents chose abortion.

Geneticists and other experts say a growing number of people are getting tested for genetic mutations before they try to get pregnant, while increasing numbers are screening embryos and fetuses and continuing only with those that get a clean bill of health.

An excerpt:

Genetic testing pushes hot-button issues: abortion, embryo destruction and worries about eugenics – selective breeding to rid a population of unwanted traits. Yet it is touching a growing number of people.

… “We’re definitely seeing decreased rates of certain genetic disorders as a result of carrier screening,” said Dr. Wendy Chung, clinical genetics chief at Columbia University.

… Eliminating disease is a noble goal but also “should give us pause,” [Dr. Barron Lerner, a Columbia University medical historian] wrote recently in the New England Journal of Medicine.

“If a society is so willing to screen aggressively to find these genes and then to potentially to have to abort the fetuses, what does that say about the value of the lives of those people living with the diseases?” he asked.
