A Swedish scientist named Fredrik Lanner was able to edit the DNA in healthy human embryos for the first time. Lanner is a developmental biologist at the Karolinska Institutet in Stockholm has been genetically modified the healthy human embryonic using the genetic engineering tools called CRISPR-Cas9.

Theoretically, this research may help us better understand the role of genetics in the development of the embryo, so that it can be used to prevent certain diseases. However, some scientists are concerned, that the DNA editing could have dangerous consequences and could be at risk of entering the faulty gene into the human genome, then causing the new disease.

"When genetically modifying human embryos, that means you change the genetics of all cells in the body of the fetus, future generations of humans. This change is permanent and irreversible, we do not know what would happen," said Darnovsky.

Additionally, Lanner also agree that more research is needed before the experimental production of genetically modified babies done, to ensure that the Darnovsky concerns not be true.. *** [EKA | FROM VARIOUS SOURCES | MEDICAL DAILY]
