To ask the Secretary of State for Health, what estimate he has made of the cost to the public purse of (a) treatments for mitochondrial disease involving mitochondrial donation and (b) treatments for mitochondrial disease that do not involve mitochondrial donation in each of the next five financial years.

The Government’s analysis of estimated costs and benefits is contained in the Impact Assessment that was laid in Parliament, together with the Draft Human Fertilisation and Embryology (Mitochondrial Donation) Regulations 2015, on 17 December 2014.

The cost over 10 years was estimated at £11.1 million with the monetised benefit estimated at £329.2 million.
