With the Snip of a Gene, Scientists Hope To Erase High Cholesterol For Life

CNN reports that “A one-time snip of a key gene lowered heart-clogging cholesterol by about 50% over an entire year with no adverse effects, scientists have reported.” The overwhelmingly positive results were found in four people who had taken the highest dose of the experimental treatment during a pilot study published in The New England Journal of Medicine in November 2025.
