Mutant Mouse Reveals New Wrinkle in Genetic Code

Call it a mystery with a stubby tail: an odd-looking mouse discovered through a U.S. government breeding program in the 1940s that had a short, kinky tail and an extra set of ribs in its neck — and nobody knew why.

A team of scientists led by researchers at the University of California, San Francisco has now spilled the genetic secrets of this mutant rodent. In doing so, they may have uncovered a new wrinkle in the genetic code — an entirely unrecognized way our bodies regulate how genes are expressed in different tissues throughout life.
