Cholesterol and heart disease risk could be lowered with a single injection
People born with natural mutations that disable a specific gene have a lower risk of heart disease, with no apparent side effects. Now a single injection has successfully disabled this same gene in animal tests for the first time.
This potential treatment would involve permanently altering the DNA inside some of the cells of a person’s body [with CRISPR], so doctors will have to be sure it is safe before trying it in people. But the benefits could be enormous.
