New DNA editing method reduces hereditary disease risks
For the first time, the "Base Editing" technique was used in a study on human embryos, where three genes related to blood cholesterol and hereditary blood diseases were modified. The goal was to improve future treatment options and reduce the risks associated with older techniques like CRISPR. The research showed that the technique is precise and safe, with few genetic errors and no chromosomal abnormalities, increasing scientists' confidence in its future use for treating serious diseases before birth.
