“Our real concern will be massive increases in the number of abortions,” said Rabbi Moshe Tendler, professor of bioethics at Yeshiva University. “You have a young couple, 22, 23, 24 years old, and they don’t plan to have more than two or three children. Why take a defective child? I call it the perfect baby syndrome. The perfect baby does not exist.”
Rabbi Avram Reisner, a bioethicist on the Conservative movement’s Committee of Law and Standards, says abortion by whim is clearly prohibited.
“Judaism is not pro-life,” said Reisner, the spiritual leader at Congregation Chevrei Tzedek in Baltimore. “Jewish law allows abortion. And it is not pro-choice. It is concerned with managing the health of the mother. It does not support abortion as a parental whim.”
The Reform movement, though adamantly pro-choice, has a similar position.
“Abortion should not take place for anything other than a serious reason,” said Knobel of the Spertus Institute, “hopefully in consultation with a religious or ethical adviser.”
As far as Jewish ethics are concerned, prenatal whole genome sequencing has some elements in common with current genetic testing.
Embryos of Ashkenazi Jews routinely are tested for such diseases as Tay-Sachs and the breast cancer genes BRCA – two illnesses disproportionately common among Ashkenazim.
In haredi Orthodox communities where arranged marriages are common, matchmakers routinely consult databases that hold genetic information anonymously to see whether a match would face a genetic obstacle. That practice, and genetic testing during pregnancy, has practically eliminated Tay-Sachs disease in the American Ashkenazi community, according to Michael Broyde, professor at the Emory University law school and a member of the Beth Din of America, an Orthodox rabbinical court.
