The UK’s fertility regulator has given approval for the “cautious use” of techniques to create a baby using the DNA of 3 people. [1]
The Human Fertilisation and Embryology Authority (HFEA) announced its “historic” decision December 15 and said that it would begin accepting applications from fertility clinics that wish to become licensed to perform the procedure. The HFEA said 3-parent baby technique, as it is commonly called, will help prevent a small number of children from inheriting potentially fatal diseases from their mothers. [2]

A controversial fertility treatment requiring 3 genetic parents was recently approved by an elite panel of U.S. scientists and ethicists.
The 12-member panel, assembled by the National Academies of Sciences, Engineering and Medicine, released a 164-page report outlining how scientists could ethically carry out such genetic engineering for the purpose of eliminating rare mitochondrial diseases – a process that would exclude girls.
