Huntington's disease typically presents before which age?

Explanation:
Huntington's disease typically begins in early adulthood, most often around the third decade of life. Symptoms such as chorea, along with cognitive and behavioral changes, usually emerge around age 30, with some variation in the 20s to 40s. The condition is caused by an autosomal dominant CAG repeat expansion in the HTT gene, and longer repeats can lead to earlier onset (juvenile cases exist but are rare). So, the most common onset is near age 30, which is why this point is chosen.
