The structure of the MutSβ molecular machine gives us more clues to the mechanism of CAG repeat expansion and how we can target it. 

A trial tested stem cells from human teeth as a possible treatment for HD. The approach appeared safe with some improvements in symptoms, but the small size of the study and the unclear underlying science of this approach means caution is urged.

A new study uses ultra-sensitive research techniques to map DNA changes across the entire spectrum of CAG repeat lengths, revealing where intermediate repeats fit in the genetic landscape
