Detailed explanation-1: -If you have a history of Huntington’s disease in your family (especially if a parent or grandparent had it), you can have a test to see if you’ll also get it. It’s up to you to decide if you want to have the test. Lots of people at risk of Huntington’s disease decide they’d rather not know until any symptoms appear.

Detailed explanation-2: -Huntington’s disease (HD) is named after George Huntington, who described it among residents of East Hampton, Long Island in 1872. It is a hereditary neurodegenerative disease. In 1993, a collaborative group of investigators discovered the gene that causes HD.
