This blog is about adult relationships, not about reproductive technologies, but the issue of reproduction and raising children is often brought into discussions about how laws treat same-sex, polyamorous, and consanguinamorous relationships. So with that in mind, it was interesting to see this report from Kerry Sheridan at yahoo.com...
Science!
For now, it is being used to avoid deadly disorders, but as the technology advances and becomes more affordable, it could be used on an elective basis.
The world's first baby has been born using a controversial new technique by US scientists to include DNA from three parents in the embryo, said a report.
The baby boy was born five months ago in Mexico to Jordanian parents, and is healthy and doing well, said the report in New Scientist magazine, described as an "exclusive."That's good news.
The boy's mother carried genes for a disorder known as Leigh Syndrome, a fatal nervous system disorder which she had passed on to her two previous children who both died of the disease.
She had also suffered four miscarriages.
The woman, whose identity was withheld by New Scientist, and her husband sought the help of John Zhang, a doctor from the New Hope Fertility Center in New York City to have a baby that would be genetically related to them but would not carry the inherited disease.That is the big draw with this; having a child genetically related to both or all of the people in the relationship while avoiding serious diseases and disorders.
Since the mother carried the genes for the disease in her mitochondria, or DNA that is passed down from the maternal side, Zhang used her nuclear DNA and combined it with mitochondria from an egg donor, in a technique known as spindle nuclear transfer.
"He removed the nucleus from one of the mother's eggs and inserted it into a donor egg that had had its own nucleus removed," said the report.
"The resulting egg –- with nuclear DNA from the mother and mitochondrial DNA from a donor -– was then fertilized with the father's sperm."
For now, it is being used to avoid deadly disorders, but as the technology advances and becomes more affordable, it could be used on an elective basis.
