All about Huntington's Disease
By Jordan Taylor
What is Huntington's Disease?
Huntington's Disease is a brain disorder that affects a person's ability to think, talk, and move.
The disease destroys cells in the basal ganglia, the part of the brain that controls movement, emotion, and cognitive ability. HD is caused by a mutation in a gene on chromosome 4. The job of its protein product, huntingtin, is to direct the delivery of small packages (vesicles containing important molecules) to the outside of the cell.
