Reproductive decision making of aunts and uncles of a child with cystic fibrosis: genetic risk perception and attitudes toward carrier identification and prenatal diagnosis.
This paper evaluates the perceived genetic risk, the perceived burden, the impact on reproductive decision making, and the attitudes of aunts and uncles of a child with cystic fibrosis toward carrier identification, prenatal diagnosis, and pregnancy termination. A mailed questionnaire was sent to the aunts and uncles of 32 CF children (1) who attended the Paediatric Department of the University Hospital and (2) whose parents agreed to give the names and addresses of their sibs. The results for the 109 respondents aged less than 40 years are discussed. About one-fourth of them was aware of the "approximate" level of the risk to be a carrier of the CF gene and/or of the risk of having a CF child themselves. Nevertheless the subjective evaluation of the genetic risk has played a part in the reproductive decision-making process of at least 39% of the respondents. About three-fourths would (probably) make use of heterozygote detection and would (probably) ask for prenatal diagnosis should they become pregnant. It is striking that less than half of the group would interrupt the pregnancy should the fetus be affected. The intention to use prenatal diagnosis was significantly correlated with age and educational level while the acceptance of pregnancy interruption was significantly correlated with perceived burden, respondents' age, and health situation of the proband.
