By Jon Holmlund The Thursday, Dec 13 edition of the Wall Street Journal carries this headline: “Doubts Arise Over Gene-Editing Claim.” The work behind the recent report that the world’s first two gene-edited babies had been born has been publicly discussed, but the details have not yet been published for full scientific review. Apparently …

By Steve Phillips I appreciate the prior posts by Jon Holmlund and Mark McQuain regarding the recent announcement of the birth of genetically modified twins in China. Much has been written about why this should not have been done, but something very significant has been left out of most of those responses. They have failed …

By Mark McQuain November 2018 will go down as one of the most pivotal points in human history. Jon Holmlund covered the facts in his last blog entry. Regardless of what you think about the ethics of He Jiankui’s recent use of CRISPR to alter the human genomes of IVF embryos and his decision to …

By Mark McQuain Almost exactly one year ago, this blog asked rhetorically whether your polygenic risk score was a good thing. Jon Holmlund raised this issue again last week, mentioning a company called Genomic Prediction. This company’s claim about the merits of their technology deserves close ethical scrutiny and is my reason for mentioning them …

Lyme disease is caused by a type of bacteria that lives in mice, which are considered a “reservoir” for the disease-causing agent. Ticks bite the mice, pick up the bacteria, and then infect people when they bite them. (Ticks are called the “vector” for the disease.) If mice were immune to the bacteria, their immune …

Last month’s announcement claiming the birth of the world’s first genome-edited babies has sparked a furore over how to regulate this cutting-edge technology (see Nature 563, 607–608; 2018, and Nature564, 5; 2018). In our view, piling up scientist-led conferences modelled on Asilomar in 1975 (see Nature 526, 293–294; 2015) without any clear consensus is futile.

Before last week, few people had heard the name He Jiankui. But on November 25, the young Chinese researcher became the center of a global firestorm when it emerged that he had allegedly made the first crispr-edited babies, twin girls named Lulu and Nana. Antonio Regalado broke the story for MIT Technology Review, and He himself described the experiment at an international gene-editing summit in Hong Kong. After his talk, He revealed that another early pregnancy is under way.
It is still unclear if He did what he claims to have done. Nonetheless, the reaction was swift and negative. The crispr pioneer Jennifer Doudna says she was “horrified,” NIH Director Francis Collins said the experiment was “profoundly disturbing,” and even Julian Savulescu, an ethicist who has described gene-editing research as “a moral necessity,” described He’s work as “monstrous.”

A Chinese scientist recently claimed he had produced the world’s first gene-edited babies, setting off a global firestorm. If true — the scientist has not yet published data that would confirm it — his actions would be a sensational breach of international scientific conventions. Although gene editing holds promise to potentially correct dangerous disease-causing mutations and treat some medical conditions, there are many safety and ethical concerns about editing human embryos.
Here are answers to some of the numerous questions swirling around this development.

On the one hand, reports of a rogue scientist, He Jiankui, who contravened the scientific and ethical norms that should guide the development of human genome editing reinforces the need for clarity about those norms and international monitoring of advances in the field. On the other hand, it shows the weaknesses and limitations of voluntary efforts – like the summit – to guide scientists’ practices. They lack any real enforcement power on their own, and have largely served to ensure that human genome editing research can continue, rather than promote reflection on whether we should edit the human germline in the first place.

BEIJING — China said on Thursday that it had suspended the work of a scientist who claims to have created the world’s first genetically edited babies, saying his conduct appeared to be unethical and in violation of Chinese law.
The scientist, He Jiankui, announced on Monday that he had used the gene-editing technique Crispr to alter embryos, which he implanted in the womb of a woman who gave birth to twin girls this month. At an international conference on Wednesday, he asserted that he was proud of what he had done.

Unlike most cells in our bodies, the neurons in our brain can scramble their genes, scientists have discovered. This genome tampering may expand the brain’s protein repertoire, but it may also promote Alzheimer’s disease, their study suggests.
“It’s potentially one of the biggest discoveries in molecular biology in years,” says Geoffrey Faulkner, a molecular biologist at the University of Queensland in Brisbane, Australia, who wasn’t connected to the research. “It is a landmark study,” agrees clinical neurologist Christos Proukakis of University College London.

A Chinese researcher claiming to have led a team that genetically edited human babies is now under investigation, as well as an American professor who might have helped him.
He Jiankui, an associate professor at Shenzhen’s Southern University of Science and Technology of China, revealed his gene editing work on Monday to an organizer of an international conference on gene editing in Hong Kong. He told the Associated Press he altered the DNA of twin girls born this month to resist HIV and AIDS virus. He said he’s altered embryos for seven couples in fertility treatments, but only had one pregnancy result.

A Chinese researcher claims that he helped make the world’s first genetically edited babies — twin girls born this month whose DNA he said he altered with a powerful new tool capable of rewriting the very blueprint of life.
If true, it would be a profound leap of science and ethics.
A U.S. scientist said he took part in the work in China, but this kind of gene editing is banned in the United States because the DNA changes can pass to future generations and it risks harming other genes.

People from minority ethnic backgrounds are set to lose out on medical benefits of genetics research due to an overwhelming bias towards studying white European populations, a leading scientist has warned.
Prof David Curtis, a geneticist and psychiatrist at University College London, has called on funding bodies to do more to address the emerging issue that genetic tests developed using samples from white Europeans can give meaningless results when applied to other ethnic groups. The problem could intensify as the clinical applications of genetics expand over the next decade.

The picture of genetic privacy that emerges from this systematic literature review is complex and riddled with gaps. When asked specifically “are you worried about genetic privacy,” the general public, patients, and professionals frequently said yes. In many cases, however, that question was posed poorly or only in the most general terms. While many participants expressed concern that genomic and medical information would be revealed to others, respondents frequently seemed to conflate privacy, confidentiality, control, and security. People varied widely in how much control they wanted over the use of data.
