Huntington's disease is a single gene disorder found in the dominant gene. So only one person who has the potential to have it is needed to pass the disorder to their offspring instead of two. That is what make Huntington's Disease so dangerous, that it is easily passed on. Since Huntington's is a single gene disorder, males are more likely to get it from their parents if they have the potential for the disease. Since males have an X and a Y cromosone.
Females have two X cromosones.
In the early stages of Huntington's, a person may experience twitching motions in the arms, neck, and face. The victim might experience some difficulty walking. A person may have some difficulty talking due to brain cell loss. On a period of 15 years, the patient becomes steadily worse. Death becomes imminent in a 10-20 year period.
