Biotech founder argues gene-editing human embryos is a moral imperative

Cathy Tie, founder of Origin Genomics, argues in Trends in Genetics that gene-editing human embryos is a moral imperative and calls for public funding and new regulatory pathways. Her company launched in March with plans to bring gene-edited embryos to IVF clinics. Critics like Stanford's Hank Greely say screening tools already address most inherited disease risk, making embryo editing unnecessary for all but a tiny fraction of cases.

Key Facts

Cathy Tie, 30, founded Origin Genomics in March with plans to bring gene-edited embryos to IVF clinics.
Tie's commentary in Trends in Genetics calls for public funding and new regulatory pathways for gene-edited babies.
Hank Greely, director of Stanford's Center for Law and the Biosciences, says embryo editing would help 'a fraction of a fraction of a fraction' of people.
Dozens of countries have banned gene-editing of human embryos intended for pregnancy.
Ian Watts and Cheyenne Ziegler produced eight chromosomally normal embryos across three IVF rounds, but only three without Watts' Charcot-Marie-Tooth variant.

The Moral Argument

Cathy Tie, founder of Origin Genomics, argues in Trends in Genetics that gene-editing human embryos is not just urgent but a moral imperative. Her company launched in March with plans to bring gene-edited embryos to IVF clinics. Tie calls for public funding and new regulatory pathways to advance gene-edited babies toward clinical use.

Scientific and Ethical Risks

Germ-line gene editing modifies embryos, and any changes could be passed to future generations. Off-target DNA edits could introduce new health risks that are also heritable. Hank Greely, a Stanford law professor, warns that first human trials have sometimes led to deaths without clear warning signs. Dozens of countries have banned gene-editing of human embryos intended for pregnancy.

IVF Limitations and Patient Cases

Critics argue that IVF combined with genetic screening already identifies disease-free embryos, making embryo editing unnecessary for most people. Greely says embryo editing would help only 'a fraction of a fraction of a fraction' of cases. Ian Watts and Cheyenne Ziegler underwent three IVF rounds to avoid passing on Watts' Charcot-Marie-Tooth disease. Their three rounds produced eight chromosomally normal embryos, but only three without the disease variant. Those three embryos are likely insufficient for the three or four children the couple hopes to have.
