I can respond in this way. In the general science, concerns have been referred to. A mismatch between nuclear and the mitochondrial DNA could cause severe health problems in children conceived with this technique: problems such as infertility, reduced growth, impaired learning, faster ageing and early death. Are those not sufficiently serious for us to be extremely concerned?

I support the work to combat this terrible disease, some of which is being pioneered by my local university, Newcastle, and I will be urging the Government to proceed with the trials, but the question is this. The new IVF technique that has been pioneered at Newcastle has proved to be successful in the laboratory, but the current law prevents it from being tested in a clinical trial or used in clinical practice. That is what we need to change. Without those clinical trials, we cannot progress and deal with this terrible disease.

That is very interesting but the point I am making is that at the moment such clinical trials would involve children. Two peer-reviewed articles in Nature have suggested that mitochondrial transfer is inherently risky, one of them citing a figure of 52% of embryos created through MST having chromosomal abnormalities.
