Huntington, surprising mechanism

Surprise finding sheds light on what causes Huntington's disease, a devastating fatal brain disorder
Scientists are unraveling the mystery of what triggers Huntington’s disease, a devastating and fatal hereditary disorder that strikes in the prime of life, causing nerve cells in parts of the brain to break down and die.
New findings shed light on cause of Huntington's disease progression
A new study of nerve cells affected by Huntington’s disease (HD) reveals that the disease-causing gene slowly expands over time, but doesn't start causing harm until it hits a toxic threshold that rapidly leads to the nerve cell’s death.
Study finds surprising way that genetic mutation causes Huntington's disease, transforming understanding of the disorder
Scientists have discovered a surprising mechanism by which the inherited genetic mutation known to cause Huntington's disease leads to the death of brain cells. The findings change the understanding of the fatal neurodegenerative disorder and suggest potential ways to delay or even prevent it.
A better understanding of Huntington’s disease brings hope
But Huntington’s second, self-preserving, oddity is that unlike most genetic disorders it rarely manifests until well into adulthood, giving plenty of time for it to be passed on. The result is families where half the members are living under premature death sentences.
New Research Sheds Light on the Causes of Huntington’s Disease
If you’ve ever heard of Huntington’s disease, you know how devastating it can be. This hereditary brain disorder slowly robs people of their ability to think, move, and even communicate. The disease’s progression is relentless,
