In Vitro Fertilisation Patient Pregnant With Wrong Embryos

Receiving a call that you are pregnant with some strangers’ children — in vitro fertilizaitonnightmare medical scenario of the future? Via the Sydney Morning Herald:

A woman who underwent fertility treatment at a clinic in Rome became pregnant with the twins of another couple after their embryos were mixed up.

A fertilised egg has 98 per cent of its DNA held in its nucleus. Half of this will be from the mother and half from the father. The remaining 2 per cent is what’s known as mitochondrial DNA – DNA in the cells’ “powerhouses” that are found outside of the egg’s nucleus, and are inherited solely from the mother.

Gene mutations in a woman’s mitochondrial DNA can cause mitochondrial disease in her children. The effects can range from mild, almost symptomless disease to serious and often fatal conditions. Researchers are aiming to avoid these serious conditions using donor eggs with mutation-free mitochondria.
