New Gene Therapy Method to prevent certain genetic diseases tested

Researchers have devised a method that will prevent certain genetic diseases from passing from mother to child.  The technique prevents the transfer of defective DNA from the mitochondria of the mother egg cell to child.

What is the method?

In this therapy the firstly, nucleus of the mother’s as well as the donor’s egg is removed. Then mother’s nucleus is transferred into the nucleus deficient donor’s egg. By doing this DNA defects arising from mitochondrial genetic material of the mother can be avoided. The egg is then fertilized by the sperm and then it is replanted into the mother and develops a healthy baby.
