CRISPR HALTED MUSCULAR DYSTROPHY IN DOGS. ARE HUMANS NEXT?

In a study published Thursday in Science, a team led by Eric Olson at the University of Texas Southwestern Medical Center used Crispr to successfully modify the DNA of four young dogs, reversing the molecular defect responsible for their muscle wasting disease. DMD isn’t an obvious candidate for Crispr’s find-and-replace function; the dystrophin gene is the largest in the human genome, and there are thousands of different mutations that can all result in the disease. But Olson found a way to target an error-prone hot spot on exon 51, which he figured could, with a single slice, benefit approximately 13 percent of DMD patients.
