A multidisciplinary conference of staff from genetic centres involved with presymptomatic testing was organised in Cardiff to discuss these and other problems. Recommendations on good practice are described under four headings: pre- and post-test counselling; confidentiality in relation to test results; collection and storage of DNA, and criteria for testing.
