In what could be a major breakthrough to the treatment of hereditary diseases, Chinese scientists successfully altered the genetic code of a human embryo, said a report in RT. 


Researchers from Sun Yat-sen University in Guangzhou used a technique known as ‘base editing’ to sift through three-billion ‘letters’ of genetic code to remove a single error which is responsible for potentially deadly blood disorder. 

This is the first time researchers are demonstrating the feasibility of curing genetic disease in human embryos using this technique, according to a scientist involved in the research. The tissues taken from a patient with the blood disorder beta-thalassemia is used in the research. These tissues were then inserted into cloned human embryos. The study is published in journal Protein and Cell.
