Abstrakt: Expanded carrier screening (ECS) entails a screening offer for multiple recessive disorders at the same time, and allows testing of individuals or couples regardless of ancestry or geographic origin. Children of consanguineous couples have a higher-than-average risk of manifesting autosomal recessive disorders. This study aims to contribute to the responsible implementation of ECS for consanguineous couples. Seven semi-structured interviews were conducted with consanguineous couples who had recently participated in Whole Exome Sequencing (WES)-based ECS at Maastricht University Medical Center (MUMC+), the Netherlands. The test offered at MUMC+ covers a large number of disease-related genes (~2000), including severe, relatively mild, early- and late-onset disorders. Respondents were interviewed about their views on, and experiences with participation in WES-based ECS. Overall, participation was experienced as worthwhile: it enabled respondents to make informed choices with regard to family planning as well as to take on the presumed parental responsibility to deliver their children as healthy as possible. Furthermore, our findings suggest that (1) true consent for having this test requires timely information about the possible implications of a positive test result for specific categories of findings, as well as about the success rates of the available reproductive options; (2) the clinical geneticist can play a pivotal part in informing participants as well as providing clear information about autosomal recessive inheritance; (3) more research is needed to explore what type of genetic risk information is considered 'meaningful' by participants and actually contributes to reproductive decision-making.
