Mitochondrial DNA diseases are rare genetic disorders, which can have a devastating effect on the patients' health and well-being. There is no cure for such diseases, although recent experiments suggest that there may be a way to prevent them by genetically altering the eggs or embryos through a procedure known as mitochondrial donation. ⋯ In February 2015, the British Parliament amended the relevant legislation to allow such. a procedure, making the UK the first state to openly challenge the global policy on germline gene modification. The article presents the scientific background to the procedure and discusses the regulatory challenges brought by the first case of its legalisation.
