Scientists Propose Project To Create Synthetic Human Genome

DNA

Scientists have proposed a long-term project that involves creating a synthetic human genome or genetic blueprint for creating human beings.

A group of 25 scientists proposed their ambitious project on Thursday… an endeavor that is bound to raise concerns over the extent to which human life can or should be engineered.

The project aims to build a synthetic genome and test it in cells in the laboratory within 10 years.

The project, which arose from a secret, invitation only meeting last month at Harvard University was unveiled in the journal Science.

A synthetic human genome could potentially make it possible to create humans without biological parents – however, the scientists have said that was not their aim.

The Seattle Times reports:

The researchers said they have no intention of using these genomes — huge collections of genetic material — to make people. Instead, they said in interviews, human genomes would be used in lab experiments, inserted for example into cells or simplified versions of organs called organoids.

That might help scientists identify the effects of genetic mutations, or create safer stem cells for transplantation, said the researchers, George Church of Harvard University and Jef Boeke of New York University.

They are among 25 authors of a paper proposing the effort, which they call the Human Genome Project-Write. The paper was released by the journal Science.

The project would also include creating genomes of animals and plants and new methods to edit DNA.

Scientists can make relatively short stretches of DNA now, but creating entire genomes the size of the human one with current technology would be hugely expensive. The main goal of the new project is to cut the cost of engineering and testing big genomes more than a thousand-fold in 10 years.

The hope is to make it inexpensive enough that scientists could study “millions of genomes in dozens of cell types” to look for the effects of mutation, Church said.

Other potential payoffs from the project include engineering virus resistance into mammal cells that are used to make medicines, so that infections don’t shut down production, he said. It could also help efforts to genetically modify pigs so that organs from them can be transplanted into people without fear of rejection, Boeke said.

The researchers aim to launch the effort this year after raising $100 million in support from public, private, philanthropic, industry and academic sources from around the world. They said it’s hard to estimate the total cost of the project, but that it’s likely less than the $3 billion Human Genome Project, which revealed the makeup of the human DNA.

The project would seek public involvement and study the ethical, social and legal implications of the work from the start, the researchers said in Science. “It’s important to engage legal and ethical scholars and society at large to really help shape the goals as well as communicate the reasons that we’re launching this project,” Farren Isaacs of Yale University, another author of the paper, said in an interview.

Researchers also must study the potential for misuse of the new technology and how to prevent that, Church said.

Word of a closed meeting about the project leaked out last month. Two observers who criticized that gathering told the AP in a joint statement this week that they were pleased by the Science paper’s commitment to public involvement, but they still had reservations about the project.
