What is the mechanism identified by the new Huntington's disease research, and how does it explain the disease's delayed onset?

Huntington's disease, caused by a genetic mutation, has puzzled scientists due to its late-onset symptoms despite the mutation being present from birth. New research reveals that the mutation remains harmless for decades, gradually increasing until it surpasses a threshold of 150 CAG repeats, triggering toxic protein production and neuronal cell death.
