Although Huntington’s disease (HD) is rare, it deserves particular attention not only because of its devastating effects and inevitable progression as well as the familial ramifications, but also because of its potential utility as a model for other neurodegenerative diseases and psychiatric disorders. An autosomal dominant CAG trinucleotide repeat disorder, HD was first comprehensively phenotyped in an elegant study in 1872 by George Huntington, who clearly described the inheritance pattern and motor characteristics of the disease. The responsible gene locus was eventually found on chromosome 4 in a landmark paper in Cell in 1993. It is commonly accepted that 27–35 CAG repeats are ‘unstable’ and may produce disease in offspring, 36–39 repeats lead to later-onset disease and higher repeat lengths lead to inevitable disease with motor onset between the ages of 30–50 years. Several recent robust, large-scale prospective cohort studies have intensively studied the clinical and imaging...
