Gene editing success for haemophilia

BioNews - Gene editing success for haemophilia: Scientists have, for the first time, successfully treated a blood disorder by repairing errors in the DNA of a living animal. Researchers from the Children's Hospital of Philadelphia, together with California-based Sangamo BioSciences, have applied an innovative genome editing technique to treat haemophilia B, which affects around one in 30,000 boys and men.

Editor: The operative words are "for the first time." I imagine everyone thinks this is the purpose of genetic testing -- to treat genetic errors -- but it's not. Not so far. The purpose of genetic currently is to eliminate the bearers of defective DNA.
