Mitochondrial donation is a technique that gives couples affected by mitochondrial DNA disease the opportunity to have a healthy child born with working mitochondria. We have responded to the Human Fertilisation and Embryo Authority’s (HFEA) consultation on the regulation of mitochondrial donation. Though this technique will only benefit a handful of our members, we see this issue as a paradigm for the future delivery of innovative treatments in the UK, so we continue to follow the issue and present the view of the patient community.
