Designer babies are on their way, said experts in genetic engineering as they called for a global ban on the practice.

It is thought that studies involving the use of genome-editing tools to modify the DNA of human embryos will be published shortly, said the authors of a paper in Nature.

The articles lead author, Professor Jennifer Doudna of the University of California at Berkeley, led the team that developed the gene-editing technique that she now wants restricted.

She and her colleagues have now warned of the ethical and safety implications of research that could lead to the birth of what laymen might term super humans.

In our view, genome editing in human embryos using current technologies could have unpredictable effects on future generations, they said. This makes it dangerous and ethically unacceptable. Such research could be exploited for non-therapeutic modifications.

It is possible, for example, for the technology to make unintended changes to DNA, The New York Times reported.

But they are also worried that a public backlash could halt work on disease fighting techniques in somatic (non-reproductive) cells.

Genome-editing technologies may offer a powerful approach to treat many human diseases, including HIV/Aids, haemophilia, sickle-cell anaemia and several forms of cancer, they said.

Scientists at the Hubrecht Institute in the Netherlands reported in Cell Stem Cell two years ago that the technique could repair the cystic fibrosis mutation.

A group of 18 scientists and ethicists today warned that a revolutionary new tool to cut and splice DNA should be used cautiously when attempting to fix human genetic disease, and strongly discouraged any attempts at making changes to the human genome that could be passed on to offspring.

Among the authors of this warning is Jennifer Doudna, the co-inventor of the technology, called CRISPR-Cas9, which is driving a new interest in gene therapy, or "genome engineering." She and colleagues co-authored a perspective piece that appears in the March 20 issue of Science, based on discussions at a meeting that took place in Napa on Jan. 24. The same issue of Science features a collection of recent research papers, commentary and news articles on CRISPR and its implications.

"Given the speed with which the genome engineering field is evolving, our group concluded that there is an urgent need for open discussion of the merits and risks of human genome modification by a broad cohort of scientists, clinicians, social scientists, the general public and relevant public entities and interest groups," the authors wrote.

Doudna, director of UC Berkeley's Innovative Genomics Initiative, was joined by five current and two former UC Berkeley scientists, plus David Baltimore, a Nobel laureate and president emeritus of the California Institute of Technology, Stanford Nobelist Paul Berg and eminent scientists from UC San Francisco, Stanford, Harvard and the universities of Wisconsin and Utah. Several of these scientists are currently involved in gene therapy to cure inherited diseases.

Latest of many warnings

Such warnings have been issued numerous times since the dawn of genetic engineering in 1975, but until now the technology to actually fix genetic defects was hard to use.

"However, this limitation has been upended recently by the rapid development and widespread adoption of a simple, inexpensive and remarkably effective genome engineering method known as CRISPR-Cas9," the scientists wrote. "The simplicity of the CRISPR-Cas9 system enables any researcher with knowledge of molecular biology to modify genomes, making feasible many experiments that were previously difficult or impossible to conduct."

Correcting genetic defects

Scientists today are changing DNA sequences to correct genetic defects in animals as well as cultured tissues generated from stem cells, strategies that could eventually be used to treat human disease. The technology can also be used to engineer animals with genetic diseases mimicking human disease, which could lead to new insights into previously enigmatic disorders.
