Webgroup of patients, with CAG repeats between 27 and 35, may show HD phenotypes and are at risk of passing extended alleles to offspring through the process of gene anticipation. Patients with 36–40 CAG repeats may be considered of ‘reduced penetrance’ and are at higher risk of developing HD but the age of onset of symptoms may be later. its not going to happen
