RegistryObjectives: 

Define phenotypical characteristics of the European HD population

Find out who might be interested and available to participate in studies

Find out how affected people and their relatives are coping

Who can take part:

At risk/gene positive patients with/without symptoms of HD

Companions 

Control participants (including gene negative family members)

Registry will facilitate:

Observational studies

Interventional trials

Biomarker detection

Identification of genetic/biological modifiers

Development and validation of clinical outcome measure

Studies of phenotypic subgroups, e.g. JHD
