📝 Explanation:
Huntington's disease is a relatively rare genetic disorder with a prevalence of approximately 1 in 10,000 individuals. It is an autosomal dominant condition, meaning that a person only needs to inherit one copy of the mutated gene from a parent to develop the disease. The onset is typically in the fourth or fifth decade of life, and it is characterized by chorea, behavioral disturbances, and progressive cognitive decline.
