Predictive testing for Huntington disease: I. Description of a pilot project in British Columbia

Authors


Abstract

The discovery of DNA markers linked to the gene causing Huntington disease (HD) has allowed the development of predictive testing programs for persons at-risk. A pilot program was established in British Columbia in November 1986. Ninetyfive persons are currently enrolled. The major objective of this project is to introduce and evaluate a protocol for the delivery of test results to persons at-risk for HD. The criteria for entry and details of the psychosocial assessment before and after receiving a modified risk are presented. The guidelines that are developed from this project will have major applications for predictive testing programs for other late onset autosomal dominant disorders.
