'Chemical surgery' can correct genetic mutations behind many diseases – study

Fresh DNA base editing breakthrough brings hope of potential treatment for huge number of diseases that arise as a result of a single genetic 'misspelling'

A breakthrough in "chemical surgery" that can correct a type of genetic mutation behind a host of diseases has been unveiled by researchers.

Scientists are hopeful that the approach could offer new ways to understand - and even one day tackle - certain human genetic diseases by correcting mutations in a patient's body.
