The purpose of this study is to identify health management concerns and needs of family members of asymptomatic and symptomatic persons with mutation in the gene for Huntington Disease (HD).

This is an observational study with three phases. In Phase 1, focus groups consisting of family members of persons with HD Gene mutation will be conducted and data collected to be analyzed through content analysis to identify salient themes and key issues. In Phase 2, a survey instrument will be developed and field-tested in order to describe the health care needs, management strategies, and needs for health and social services of relative/significant others of asymptomatic and symptomatic persons with the mutation in the gene for HD.

In Phase 3, the survey will be distributed to family members of asymptomatic and symptomatic persons with mutation in the gene for HD and frequencies and comparisons of survey responses according to respondent characteristics will be reported.

• Family members of asymptomatic and symptomatic persons with mutation in the gene for Huntington Disease

Family members or significant others, age 14 or older, of persons who 1) have received a positive result from predictive testing for a mutation in the HD gene, 2) are symptomatic and living at home, and 3) are symptomatic and are living in a long-term care institution were the population of interest for this study.
