Correcting Genetic Spelling Errors With Next-Generation Crispr

Sam Berns was my friend. With the wisdom of a sage, he inspired me and many others about how to make the most of life. Afflicted with the rare disease called progeria, his body aged at a rapid rate, and he died of heart failure at just 17, a brave life cut much too short. My lab discovered the genetic cause of Sam's illness two decades ago: Just one DNA letter gone awry, a T that should have been a C in a critical gene called lamin A. The same misspelling is found in almost all of the 200 individuals around the world with progeria. This story is from the WIRED World in 2025, our annual trends briefing.
