Background Information

Huntington disease (HD) is a progressive disorder of motor, cognitive, and psychiatric disturbances. The mean age of onset is 35 to 44 years and the median survival time is 15 to 18 years after onset.

The diagnosis of HD rests on positive family history, characteristic clinical findings, and the detection of an expansion of CAG trinucleotide repeats in the HD gene.
