The most frequent type of interaction between counsellor and counsellee is when factual information is given, but sometimes "factual" information is difficult to obtain. How do counsellors deal with "uncertain" knowledge in genetics? Arguments and assumptions are presented and the finding of a 27 CAG repeat in the Huntington gene is used as an example. However, the questions "how far does the duty to inform reach?" and "to what extent is the doctor responsible?" are important in the whole field of genetics, and will be even more important in the future. The aims of science and clinical practice are discussed; we conclude that counsellors run the risk of taking on an infinite responsibility. http://repub.eur.nl/res/pub/9052/ 1999-01-01T00:00:00Z The dilemmas in counselling a mildly retarded female with the fragile X syndrome and her retarded partner are presented. The fragile X syndrome is an X linked mental retardation disorder that affects males and, often less severely, females. Affected females have an increased risk of having affected offspring. The counselling of this couple was complicated by their impaired comprehension which subsequently impaired their thinking on the different options. The woman became pregnant and underwent CVS, which showed an affected male fetus. The pregnancy was terminated. Whether nondirective counselling for this couple was the appropriate method is discussed and the importance of a system oriented approach, through involving relatives, is stressed.
