Introduction: Prenatal diagnosis (PND) raises ethical dilemmas such as the option of termination of pregnancy (TOP) in cases with severe outcome. Prader-Willi Syndrome (PWS), a complex neurogenetic syndrome with high morbidity and mortality throughout life. Recently, a unique prenatal phenotype was reported and TOP becomes a possibility.

Objective: To explore factors influencing the attitudes of parents of PWS children toward PND and TOP concerning a hypothetical pregnancy with a PWS fetus.

Methods: All 85 parents of individuals with PWS were interviewed regarding their attitudes towards PND and TOP using semi-structured questionnaire.

Results: Fifty-seven parents were supportive of invasive PND and 28 of non-invasive tests only; none opposed PND. Thirty eight favored TOP, additional 31 supported TOP under certain conditions such as spiritual advice, 15 were categorically against TOP. Attitudes correlated with religiosity (p < 0.025), mother's education (p < 0.001), mother's work status (p < 0.001), current age of the child with PWS (p < 0.008). Couples had similar attitudes regarding PND and TOP. No correlation was found with gender, genetic subtype and parental age.

Conclusions: Most parents of individuals with PWS support PND, however less than half support TOP. Religiosity was the most influential factor. Familial worldview should be taken into account during prenatal counseling.

The widespread use of non-invasive prenatal testing (NIPT) has turned prenatal diagnostics for chromosomal abnormalities from the exception to the rule. A common finding is the suspicion of trisomy 21 in the fetus, which should result in the offer of multidisciplinary counseling. The significance of this for decision-making by the pregnant woman has not yet been investigated.
