Huntington's disease

By David Smith

Unlike many other hereditary diseases, Huntington's is a dominant trait, directly passed down from parents to offspring. If one parent has one allele of huntington's, their children have a 50% chance of having the disease.
The allele for Huntington's disease is an inherited damaged protein, which over time damages brain cells, leading to mental and physical deterioration.
Symptoms usually begin with mild uncoordination, and progresses slowly until the host has little to no control over their own body. Victims are vulnerable to heart disease and are often injured by falls. The onset of symptoms usually begins between the ages of 35 to 44 years of age.
