In Mexico successfully conducted a unique operation for artificial insemination, which resulted in aprede 2016 to light for the first time a boy came from three parents, reports the magazine New Scientist. Child called Ibrahim Hassan.
The boy’s parents is a Muslim married couple from Jordan for almost 20 years could not have healthy children due to a rare genetic disease of his wife, Leah syndrome affecting the Central nervous system. Genes that trigger disease development are maternal mitochondrial DNA. In 2005 they had a child with this disease. The child died at the age of six years. Their second baby, born with the same disease, lived for eight months.
A team of American scientists from New Hope Fertility Center, headed by John Chan withdrew from the egg mother’s nucleus and transplanted it into the egg of another woman (the ova previously removed native core). Then modified the egg was fertilized and transferred back into the uterus of the mother. The operation was carried out in Mexico as in the U.S., this technology fertilization is prohibited. According to the doctors, the baby did not inherit a genetic disease.
In most countries, such operations are forbidden because the authorities are afraid of genetic mutations. In 2015, geneticists urged his colleagues to suspend experiments on human embryos, sperm and eggs with the use of latest technology precise editing of genes. The statement was published in the journal Nature.
According to the authors, it is necessary to declare a moratorium on such interventions into the genome to develop a rigid code of ethics. They fear that otherwise, in society there is a rejection of these technologies, which are used to correct genetic defects that will jeopardize the future of the promising methods of treatment of hereditary diseases.
The concerns are that such experiments may in future lead to the creation of “superhumans” and “designer babies” – children with certain traits and qualities. In addition, the problem is that such intervention will affect all subsequent generations.
“Man is not a lab rat and not experienced vegetable sample, – the author of the appeal, the Chairman of the Alliance for regenerative medicine in Washington Edward lanphear. Man is a unique species of our planet. I don’t question the fact that this is the boundary that mankind should not cross”.
Recently a Chinese geneticist Sensui Huang from Shanghai University of technology appealed to the ethics Committee for permission to conduct experiments for precise editing of genes in human embryos. In 2014 he and his colleagues have already conducted such experiments on monkeys, with the result that the light appeared live specimens with a modified genome.
