In March 2005, a group of experts from the European Society of Human Genetics and European Society of Human Reproduction and Embryology met to discuss the interface between genetics and assisted reproductive technology (ART), and published an extended background paper, recommendations and two Editorials. Seven years later, in March 2012, a follow-up interdisciplinary workshop was held, involving representatives of both professional societies, including experts from the European Union Eurogentest2 Coordination Action Project. The main goal of this meeting was to discuss developments at the interface between clinical genetics and ARTs. As more genetic causes of reproductive failure are now recognised and an increasing number of patients undergo testing of their genome before conception, either in regular health care or in the context of direct-to-consumer testing, the need for genetic counselling and preimplantation genetic diagnosis (PGD) may increase. Preimplantation genetic screening (PGS) thus far does not have evidence from randomised clinical trials to substantiate that the technique is both effective and efficient. Whole-genome sequencing may create greater challenges both in the technological and interpretational domains, and requires further reflection about the ethics of genetic testing in ART and PGD/PGS. Diagnostic laboratories should be reporting their results according to internationally accepted accreditation standards (International Standards Organisation - ISO 15189). Further studies are needed in order to address issues related to the impact of ART on epigenetic reprogramming of the early embryo. The legal landscape regarding assisted reproduction is evolving but still remains very heterogeneous and often contradictory. The lack of legal harmonisation and uneven access to infertility treatment and PGD/PGS fosters considerable cross-border reproductive care in Europe and beyond. The aim of this paper is to complement previous publications and provide an update of selected topics that have evolved since 2005.
2005 年 3 月,欧洲人类遗传学学会和欧洲人类生殖与胚胎学学会的一组专家开会讨论遗传学与辅助生殖技术(ART)之间的接口,并发表了一份扩展背景文件、建议和两篇社论。七年后,即 2012 年 3 月,举行了一次后续的跨学科研讨会,来自这两个专业学会的代表参加了会议,其中包括欧盟 Eurogentest2 协调行动项目的专家。会议的主要目的是讨论临床遗传学和 ART 之间接口的发展。随着越来越多的生殖失败的遗传原因被认识到,越来越多的患者在受孕前对其基因组进行检测,无论是在常规保健中还是在直接面向消费者的检测中,遗传咨询和植入前遗传诊断(PGD)的需求可能会增加。迄今为止,植入前遗传筛查(PGS)没有随机临床试验的证据来证实该技术既有效又高效。全基因组测序在技术和解释领域都可能带来更大的挑战,并且需要进一步思考 ART 和 PGD/PGS 中的基因检测伦理问题。诊断实验室应根据国际公认的认证标准(国际标准化组织-ISO 15189)报告其结果。需要进一步研究,以解决与 ART 对早期胚胎表观遗传重编程的影响相关的问题。关于辅助生殖的法律格局正在发展,但仍然非常多样化,而且往往相互矛盾。缺乏法律协调以及获得不孕治疗和 PGD/PGS 的机会不均等,促进了欧洲乃至更远地区的大量跨境生殖护理。本文的目的是补充以前的出版物,并提供自 2005 年以来演变的选定主题的最新信息。
