Brits test a new way of creating a child with three parents

Britain would allow the controversial technique of creating children using DNA of three people, a move that could help couples make their children do not inherit the rare genetic disease.

New technology will help women with "deficient" mitochondria that the children do not inheret defects that can result in diseases such as muscular dystrophy, epilepsy, heart problems, or mental retardation. One in 200 children are born each year in the UK with mitochondrial disorder.

For women with low mitochondria, scientists would take a healthy genetic material from the egg or emriona. Then he was transferred to the donor egg - an embryo that has healthy mitochondria, but the rest of the core DNA was removed. Thus, the fertilized embryo would be inserted into the womb of the mother.

Some groups opposed to artificial reproduction and believe that the destruction of eggs is immoral.

British tabloids attacked procedure which was first launched in 2008. and described as creating children three parents - mother, father and donors. For the claim that scientists say is incorrect because the amount of DNA from the egg donor insignificant.

"Scientists have developed a new procedure that could stop the transmission of these diseases," said chief medical officer in the UK, Dr Sally Davies.

A similar study done in the United States.

If British MPs agree, Britain could become the first country in the world where such a technique would use for making children. Experts say the procedure is applied to only a dozen women a year.
