Questions & Answers

Q: What is George Church's opinion of the recent news about CRISPR babies in China?

Church believes that it was not a solo effort and that the government was likely aware of the research. He also believes that the creation of CRISPR babies was a foreseeable development given the technical advances in the field.

Q: How does CRISPR actually knock out or edit genes?

CRISPR is primarily used to knock out genes rather than precise editing. It can damage specific genes, such as the ccr5 gene, making them non-functional. This can have therapeutic benefits, such as making individuals resistant to HIV.

Q: Is there a concern about potential off-target effects and mosaicism in the CRISPR baby experiment?

Mosaicism is expected in most editing experiments, but as long as a fair number of cells are properly edited, the desired effects can still be achieved. The level of mosaicism and off-target effects in the CRISPR baby experiment seemed low, but more research is needed to fully understand the long-term effects.

Q: How does George Church view the ethics and role of ethicists in gene editing projects?

Church emphasizes the importance of following ethical guidelines and regulations when conducting gene editing experiments, particularly in germline editing. He believes that ethicists play a crucial role in establishing these guidelines and ensuring the safety and efficacy of such experiments.

Summary & Key Takeaways

• George Church discusses the current state of CRISPR technology, including recent news about CRISPR babies in China.

• He explains the specific experiment conducted with the CRISPR baby and the implications of editing the ccr5 gene.

• Church highlights the importance of proper diagnosis and prevention, as well as the need for continued research and regulation in gene editing.
