'Six of my babies have died from a faulty gene'


Sharon Bernardi aged 44, from Sunderland, inherited mitochondrial disease from her mother. The condition has claimed the lives of six of her children, all of them dying within a few days of birth.

Her only surviving child, Edward, who is 20, suffers from a serious mitochondrial disease and needs constant care.

Research published in the journal Nature, has the potential to help people with these types of rare genetic disorders have healthy children.

The aim is to prevent damaged DNA in mitochondria - the "batteries" which power the cell - from being passed on by the mother.

Embryos containing DNA from a man and two women have been created by scientists at Newcastle University.

Doctors are not currently permitted to carry out the controversial procedure.
