Question

Quizplus · Accepted Answer

Huntington disease is a dominant disorder that affects the nervous system and causes progressive movement, cognitive, and psychiatric symptoms. It is caused by a mutation in the huntingtin gene, located on chromosome 4. The mutated gene codes for a toxic protein that progressively damages neurons in the brain, leading to the symptoms of the disease. The disease is inherited in an autosomal dominant pattern, which means that a person needs to inherit only one copy of the mutant gene from one parent to develop the disease.
