According to a recent analysis published in the journal Bioethics, genetically-modified babies could become a reality within two years. Author Kevin Smith, a bioethicist at Abertay University in Scotland, says that GE babies are “highly desirable” for disease protection, and gene editing is now such a “low risk” process it could be used in human embryos.

Last year, controversy surrounded Chinese scientist He Jiankui after he announced the creation of the first genetically-modified HIV-resistant babies in the world, by altering their embryos. According to Smith, the process was ethically justifiable. He says it could offer hope to parents who are at risk of transmitting serious genetic diseases to their children, and believes it is the “only conceivable way” to handle embryos that contain multiple disease-associated genes.

In a press statement, Smith said, “If several common disorders could be avoided or delayed by genetically modifying humans, the average disease-free lifespan could be substantially extended. For the time being, Smith recommends delaying genetic modification programs because “society is largely opposed to genetically modifying humans.” However, he believes implementation of the process could be less than two years away.

Last month, research was published showing that a new gene-editing technology could potentially correct up to 89% of genetic defects. Researchers say that includes genetic defects that cause diseases like sickle cell anemia.

What do you think? Are there ethical concerns surrounding genetically-modified babies? Or are the potential results worth it?
