Question

Quizplus · Accepted Answer

Huntington's disease is a genetic disorder that typically affects individuals in midlife (around age 40) and is characterized by muscle spasms, difficulty walking, and eventually leads to cognitive and psychiatric symptoms. It is an autosomal dominant disorder, meaning that a person only needs to inherit one copy of the mutated Huntington gene to develop the disease. Since Paul was an orphan with unknown family history, it's possible that he inherited the disease from one of his biological parents.
