Question

Quizplus · Accepted Answer

Huntington disease is caused by a dominant inheritance pattern, meaning if a person inherits the abnormal gene from one parent, they will develop the disease. It usually manifests in middle age, but can sometimes affect individuals in their 20s or 30s. HD is a progressive disease that can lead to death, usually within 10 to 30 years after onset.
