Hello Anon,
Thank you for posting! Huntington's Disease is actually a genetic condition that cannot be avoided by an individual.
Huntington's disease is caused by an inherited defect in a single gene. It's an autosomal dominant disorder, which means that a person needs only one copy of the defective gene to develop the disorder.
With the exception of genes on the sex chromosomes, a person inherits two copies of every gene — one copy from each parent. A parent with a defective Huntington gene could pass along the defective copy of the gene or the healthy copy. Each child in the family, therefore, has a 50 percent chance of inheriting the gene that causes the genetic disorder.
I hope this answers your question,
Rosa
