News of a positive result (meaning you have the changed gene)
would be devastating. You prefer to live without knowing whether you will someday get Huntington's disease.
You are concerned about how the results would affect your
relationships. If you test negative (you do not have the changed gene), you may
feel guilty if your brother, sister, or child tests positive. Or you may feel
angry if you test positive and your relatives do not.
You are concerned about the possibility of facing discrimination
at work or with future health insurance if your insurance pays for the test. Many people worry that genetic information released to insurance companies may affect future employment options or the cost or availability of insurance. But a law in the United States, called the Genetic Information Nondiscrimination Act of 2008 (GINA), protects people who have DNA differences that may affect their health. GINA prevents employers and health insurance companies from using DNA information about people to affect decisions. This law does not cover life insurance, disability insurance, or long-term care insurance.
You think there is no point in knowing now because there would be
nothing you could do with lifestyle or treatment to prevent the disease.
