This study examines the interface between newborn screening and prenatal diagnosis from the point-of-view of parents of screen-positive children. Many conditions covered by newborn screening represent classic (autosomal recessive) Mendelian disorders. Parents of screen-positive infants therefore often come to learn that they are carriers of the disease, and face a decision whether to test for it in future pregnancies. Semi-structured interviews were conducted in 2015-2017 with 34 Israeli parents whose child was screen positive. Three major themes emanated from the parents' attitudes toward prenatal testing for the disease in prospective hypothetical pregnancies: rejection of prenatal testing for the disease associated with the screen positive, and relying instead on newborn screening to reveal if a future baby is also sick (18/34, 53%); support of prenatal testing to get more information (7/34, 21%) and support of prenatal testing in order to abort in case of a test positive (9/34, 26%). We discuss the importance of newborn screening for reproductive decision-making, highlighting the arguments associated with positive and negative parental views of the possibility of having another child with the same condition associated with the screen-positive of the child that had already been born. The conclusions challenge the common assertion that parents pursue the dream of the "perfect child" through prenatal diagnosis that "naturally" leads to selective abortion. The diversity of views expressed by Israeli parents of screen-positive children highlights the diversity of normative scripts of "genetic responsibility" in the context of parenthood.
本研究从筛查呈阳性儿童的父母的角度,审视新生儿筛查与产前诊断之间的关联。新生儿筛查所涵盖的许多病症都属于典型的(常染色体隐性)孟德尔遗传病。因此,筛查呈阳性婴儿的父母常常得知自己是该疾病的携带者,并面临着是否在未来妊娠中进行检测的抉择。2015年至2017年期间,对34名其子女筛查呈阳性的以色列父母进行了半结构化访谈。父母对于未来假设妊娠中该疾病的产前检测的态度产生了三个主要主题:拒绝针对与筛查呈阳性相关的疾病进行产前检测,而是依靠新生儿筛查来揭示未来的婴儿是否患病(18/34,53%);支持进行产前检测以获取更多信息(7/34,21%),以及支持进行产前检测以便在检测呈阳性时终止妊娠(9/34,26%)。我们讨论了新生儿筛查对于生殖决策的重要性,强调了与父母对于再生一个患有与已出生孩子筛查呈阳性相关的相同病症的可能性的正反观点相关的论据。这些结论对一种普遍观点提出了挑战,即父母通过产前诊断追求“完美孩子”的梦想,而这“自然地”导致了选择性堕胎。筛查呈阳性儿童的以色列父母所表达的观点的多样性,凸显了为人父母背景下“遗传责任”规范脚本的多样性。
