US researchers have found a substantial way to correct an inherited disorder in women who are affected in a huge number.

It was achieved, while they were working on monkeys, by transferring genetic material which is required to create a baby from a defective egg to a healthy one, finally forming into healthy birds.

This research has raised new hopes of a treatment allowing women with defective eggs to bear children without using donor eggs. The child will, though, have a small number of genes from a third parent.

The genetic fault lies in the cell's mitochondria, which are responsible in maintaining its internal processes. Therefore the child formed with a egg containing faulty mitochondria can result in various diseases including anaemia, dementia, hypertension and a range of neurological disorders.

Researchers had failed earlier to achieve a similar transfer of healthy mitochondria into the defected cells since they got damaged during the transfer. Mitochondria is very delicate.

Lead researcher Dr Shoukhrat Mitalipov believes the technology is now ready to be tried out on human patients. The Parliament would need to amend the law before this technique can be used on humans.
