Neuro HD Huntingtons Disease: a hereditary, fatal disorder Autosomal dominant disease, characterized by cognitive decline, psychiatric illness and chorea; fatal No approved disease-modifying therapies Expanded CAG triplet repeat in HTT gene results in production of mutant huntingtin protein (mHTT); accumulation of mHTT causes progressive loss of neurons in the brain Wildtype (healthy) HTT protein critical for neuronal function; suppression may have detrimental long-term consequences 30,000 people with Huntingtons disease in the US; another 200,000 at risk of developing the condition DNA CAG Repeat RNA RNA wildtype (healthy) allele mutant allele Normal CAG Repeat Expanded CAG Repeat Healthy protein (HTT) Mutant protein (mHTT) Sources: Auerbach W, et al.
