The latest news about the first three-parent baby became the hottest one. The idea is clear from medical point of view. But three-parent baby pros and cons are still under discussion. What is your point?
The procedure of "three parents" was first successfully performed on a healthy human embryo in early 2016.
The specialists of the Oregon University proved the possibility of the conception. If the process is based on two women and one men genes, the baby will have the lowest risk of hereditary diseases.

What is a three-parent baby and how does it work?
A unique technology created the embryos with the genes of 3 parents. DNA of the second women was used to replace defective genes. Mothers transmit the genes in the mitochondria outside of the nuclei. 1 of 5 thousand newborns has the disease from a faulty mitochondrial gene.
New technology will allow giving birth to children who inherited the mitochondrial, not nuclear DNA of mother. The nuclear DNA will be removed from a healthy donor cell, and will be replaced by mother's material. The cell will get healthy mitochondrial DNA of the donor and nuclear DNA of mother.
Experiments with monkeys and the human cells did not show major deviations. Animals born from such a conception in 2009 are still healthy. Scientists are concerned about the safety of such technology for generations. Difficulties may not become apparent for several generations.
Three parents baby ethical issues remains a controversial issue. Nevertheless, it was made to reduce the risk of hereditary diseases.
Three parent baby born
In Mexico in April 2016 was born the child, the conception of which occurred with the mitochondrial DNA of a third person. Because of the ethical side of reporting we did not know about an experience until now.
Scientists believe that the method of "three parents" will allow avoiding the influence of mutations from the mother, which can lead to diseases such as the syndrome of diabetes and deafness.
The operation was conducted in Mexico by American surgeon, John Chan (John Zhang). The place of the action was chosen not by chance. The fact is that the laws of the States prohibit the application of the methods.
A Jordanian couple whose two children died from the Leia syndrome applied to John Chan. Leia syndrome is a hereditary disease, which is accompanied by a neurometabolic syndrome. The necessity of concepts from three parents was due to the presence of responsible for the development of the disease genes in the maternal mitochondrial DNA.
During the operation, John Chan removed the mitochondrial DNA of the female donor into the of a cell of the mother, securing it thus from the Leia syndrome.
At the time of the first presentation of the technology, the child was five months old. No adverse health factors are fixed.
