Question to the Department of Health and Social Care:

To ask Her Majesty's Government how many UK clinics have been granted a licence by the Human Fertilisation and Embryology Authority to undertake screening and treatment for mitochondrial disorders; how many patients at risk of producing a child with mitochondrial pathologies have undergone treatment using IVF and nuclear or spindle transfer; and how many births have been achieved following those treatments.

The Human Fertilisation and Embryology Authority has granted a licence to one clinic, Newcastle Fertility Centre at Life, to undertake screening and treatment for mitochondrial disorders.

Five patients at risk of producing a child with mitochondrial pathologies have undergone treatment using in vitro fertilisation and nuclear or spindle transfer.

No births have been achieved following those treatments to date.
