The world’s first child having the DNA of three parents were born five months ago.
To “create” a child without genetic defects transmitted by sick syndrome Leigh’s mother, the researchers used a method of in vitro fertilization. In the laboratory, they transplanted nucleus to mitochondria donor mother, and then combined with sperm father. Because this method is illegal almost all over the world to perform the procedure, the researchers went to Mexico.
Treatment nucleus transplantation to a foreign mitochondrion made eliminating child genetic defect. At the same time the boy, who came into the world in addition to the DNA of both parents, also has 0.1% of the DNA donor. In other words, the genetically has two mothers.
The child was born healthy and free of genetic defect, which in the case of natural service, were delivered by his mother.
It should be noted, however, that this method was created five embryos. Only one of them developed normally.
The procedure is controversial and is prohibited in all countries except Mexico and the United Kingdom. Even the scientific community considers it to be ethically questionable.
