[Clinical genetics in The Netherlands. II. Genetic counseling and prenatal diagnosis].
The main feature of clinical genetics is the involvement of close relatives in the diagnostics of a hereditary disorder, and the possible consequences of the findings for future generations. Complex genetic counseling is required in cases with different, possibly hereditary disorders or congenital anomalies in the family or by a syndrome with variable risks of recurrence, depending on the exact nature of the disorder; also the difficult, often emotionally charged choices with which counselees are faced demands the expertise of a clinical genetic centre. Results of follow-up studies after genetic counseling show that experience with a handicap or disease in the own environment and the presence of healthy issue are the main determinants for the decision about reproduction of persons with an enhanced genetic risk who request counseling. Because of the great variety in perception of risks and of the severity of a disorder, and because of the marked clinical heterogeneity, rigid legislation should be avoided in the field of prenatal diagnosis. In the future, the training of the clinical geneticist has to be adapted to the rapid progress in human genetics. Increasingly, the clinical geneticist will function in collaboration with other disciplines such as oncology, obstetrics and gynaecology, paediatrics and neurology; in connection with family testing and counseling, there will also be more collaboration with primary health care.
