Huntington disease

Informative genetic testing is currently available to individuals with clinical symptoms suggestive of Huntington disease (HD) and family members of individuals diagnosed with HD. Current research is focused on understanding the cellular basis of HD to inform future treatments and provide the basis for a possible cure.

Bottom line

The benefits of genetic testing for HD are limited and mainly relate to the individual’s perception of the psychological advantages of knowing whether he or she is predisposed to developing HD. There remains no cure or effective preventive therapy for the disease.
