Almaty. September 28. Silkroadnews – Chinese scientists have performed a precise surgery to correct a genetic error in a human embryo, the BBC reported.
“Precise “chemical surgery” has been performed on human embryos to remove disease in a world first, Chinese researchers have told the BBC. The team at Sun Yat-sen University used a technique called base editing to correct a single error out of the three billion “letters” of our genetic code. They altered lab-made embryos to remove the disease beta-thalassemia,” the report said.
According to scientists, this method will help to save embryos from other inherited diseases in the future.
As explained, basic editing changes the fundamental building blocks of DNA: adenine, cytosine, guanine and thymine, commonly known as A, C, G and T. All the instructions for building and controlling the human body are encoded in a combination of the four blocks. The potentially life-threatening blood disorder called beta-thalassemia is caused by a change in just a single block in the genetic code, known as a point mutation. Chinese scientists managed to fix it. They scanned DNA for errors, and then converted a G to an A, correcting the error.
It is noted that the experiments were carried out in tissues taken from a patient with a blood disorder and in human embryos made through cloning.
