Mitochondrial Replacement (Public Safety)

Debate between Lord Willetts and Huw Irranca-Davies

Monday 1st September 2014 Commons Chamber

[Huw Irranca-Davies]

Will the right hon. Gentleman give way?

[Mr Willetts]

I will give way once.

[Huw Irranca-Davies]

I thank the right hon. Gentleman for kindly giving way and for his expertise in this area. It is of particular interest to my constituents Val Thomas of Cefn Cribwr and her sister Mrs Pitt, whose family have conditions that stem from mitochondrial deficiency. Does he agree that it is important to get accuracy in the record when we quote scientists, not least the correction that has been made by Lord Winston? He said this week to The Times:

“This is a marvellous thing for people with diseases that are incredibly rare and that have terrible consequences.

I am perfectly supportive of the regulations and I would vote for them.”

[Mr Willetts]

I confirm that my understanding is also that Lord Winston supports the advances in this area.

The evidence is pretty clear that this could alleviate human suffering, but I am not a simple-minded believer that the consequences justify whatever we do. Looking at my hon. Friends assembled in the Chamber today, many may say, “All right, this alleviates mitochondrial disease, but the price—the threat to human dignity or integrity—is too great.” I should like briefly to touch on those types of objection.

First, I do not agree with my hon. Friend the Member for North East Somerset (Jacob Rees-Mogg) that this somehow creates different people. We are not talking about the nuclear DNA that makes us who we are—the characteristics of our character or appearance. This is about a very distinctive part of DNA that has been called, for us laymen, a battery part of the cell, not the nuclear DNA, so it does not affect identity.
