Abstract
The widespread use of a predictive genetic test for Huntington's disease (HD) since 1993 has brought to the forefront issues regarding genetic privacy. Although the possibility of anonymous genetic testing has been discussed, its use in the United States has not been described previously. We review the experiences of 11 genetics specialists with anonymous predictive testing for HD. We found that more men than women requested anonymous testing, for reasons that more often related to personal privacy than to insurance or discrimination concerns. A number of approaches to anonymity were used, and genetics specialists varied in the degree to which they were comfortable with the process. A number of legal, medical, and practical questions are raised, which will require resolution if anonymous testing is to be performed with a greater frequency in the future.
