Three Parent Babies – three-parent in vitro fertilisation (IVF)

Britain became the first country to allow a ―three-parent‖ IVF technique which doctors say will prevent some inherited incurable diseases

The treatment is known as ―three-parent in vitro fertilisation (IVF) because the babies, born from genetically modified embryos, would have DNA from a mother, a father and from a female donor.

Mitochondrial DNA (mDNA) is passed through the mother and mitochondrial diseases cause symptoms ranging from poor vision to diabetes and muscle wasting.

Concerns

  • Religious issues of the Church, this is also a step towards creating ―designer‖ babies; and fertilisation process may cause inherited conditions such as fatal heart problems, liver failure, brain disorders, blindness and muscular dystrophy.

What is Mitochondrial Disease/Defective Mitochondria

  • Mitochondrial disease is a chronic, genetic disorder that occurs when the mitochondria of the cell fail to produce enough energy for cell or organ function.
  • Mitochondrial failure causes cell injury that leads to cell death. When multiple organ cells die there is organ failure.
  • Mitochondrial diseases are sometimes (about 15% of the time) caused by mutations in the mitochondrial DNA (mDNA) that affect mitochondrial function.

Mitochondrial DNA: Mitochondrial DNA is separate from DNA found in the cell nucleus and does not affect human characteristics such as hair or eye colour, appearance or personality traits.
