There has been an on going debate about the plausibility of mitochondrial replacement techniques. Following a visit from a constituent who suffers from mitochondrial disease I looked into the debate further and I agree with her that we should be doing all we can to prevent this terrible disease.
There are those who object on moral or religious grounds which they are perfectly entitled to, I do think however that by not supporting these scientific advancements we are failing our constituents and allowing them to continue to suffer.
