What is the life expectancy of someone who has Huntington’s disease? Huntington’s disease is a condition that stops parts of the brain working properly over time. It’s passed on (inherited) from a person’s parents. It gets gradually worse over time and is usually fatal after a period of up to 20 years.
What race is most affected by Huntington’s disease? Frequency. Huntington disease affects an estimated 3 to 7 per 100,000 people of European ancestry. The disorder appears to be less common in some other populations, including people of Japanese, Chinese, and African descent.
Is there hope for Huntington’s disease? Huntington’s disease (HD) is an inherited disease caused by a mutation in the huntingtin gene. The mutated gene codes for a defective protein, that leads to brain changes, responsible for loss of mental and physical functions, and death. There is currently no cure and no way to slow or stop these brain changes.
Can Huntingtons skip a generation? Myth 4: HD can skip generations. Fact: The HD gene mutation never skips a generation.
