at risk

A person is considered ‘at risk’ if there is a chance they have the HD allele. This term is usually used for people who have a parent with HD, but who have not been genetically tested themselves and so do not know whether they have the disease. If a genetic test shows that someone has the HD allele, they are then considered ‘HD-positive’ or ‘gene positive’.
