This study examines the communication that occurs during routine genetic co
unselling sessions. It involves;the qualitative analysis of nine consultati
ons with one member of a clinical genetics team.
The consultations were characterised by a contrast between the sense of cer
tainty apparent in how the clinician talked about the power and promise of
the new genetics and the uncertainty communicated regarding the actual info
rmation produced by genetic tests and their limitations in solving people's
problems. There was also a contrast between how the clinician seemed to co
ntrol the format and agenda of the consultation and the apparently uncontro
llable personal and social implications of the topics discussed. We specula
te that this may be explained in terms of the clinician giving some order a
nd certainty in an area of inherent uncertainty, and where great promises a
re as yet unrealised.
