Which of the following is NOT true of Huntington's disease?

Question

Quizplus · Accepted Answer

Huntington's disease is a genetic disorder caused by a mutation on chromosome 4. It is inherited in an autosomal dominant pattern, meaning that a child has a 50% chance of inheriting the mutated gene from a parent who has the disease. It is not possible to predict with nearly 100% accuracy who will get the disease, although genetic testing can confirm the presence of the mutated gene. There is no cure for Huntington's disease and no effective treatment to slow its progression. L-dopa is used to treat Parkinson's disease, not Huntington's disease. The average age of onset of Huntington's disease is around 40 years.
