Das Verbot der pränatalen Diagnostik spätmanifestierender Erkrankungen im deutschen Gendiagnostikgesetz - eine Diskussion medizinischer und rechtlicher Aspekte und deren Implikation für die medizinethische Diskussion

Zusammenfassung: Am 1. Februar 2010 ist das Gendiagnostikgesetz (GenDG) in Kraft getreten. Die Debatte um einige Regelungsbereiche, wie beispielsweise das Neugeborenenscreening, reißt nicht ab. Ein Aspekt des Gesetzes ist im Rahmen der Debatte um die Präimplantationsdiagnostik (PID) in Deutschland unter neuen Vorzeichen zu diskutieren: Das - international bislang einzigartige - Verbot der pränatalen Diagnostik so genannter spätmanifestierender Erkrankungen, die erst nach der Vollendung des 18. Lebensjahres ausbrechen. In diesem Beitrag möchten wir Hinweise zur differenzierten Diskussion dieser in §15(2) GenDG bestimmten Verbotsnorm liefern. Obgleich Argumente, insbesondere das Recht auf Nichtwissen des geborenen Kindes, für ein solches Verbot sprechen, kommen wir aufgrund der medizinischen Sachlage und nach einer Analyse der Pro- und Kontraargumente aus ethischer und rechtlicher Sicht zu dem Schluss, dass ein generelles Verbot der pränatalen Diagnostik spätmanifestierender Erkrankungen im Sinne der Zielsetzung womöglich insuffizient ist sowie in der Begründung Inkonsistenzen zum bereits bestehenden Regelwerk aufweist, und lenken daher den Blick auf unter Umständen bessere Alternativen

Evolving minimum standards in responsible international sperm donor offspring quota

An international working group was established with the aim of making recommendations on the number of offspring for a sperm donor that should be allowable in cases of international use of his sperm. Considerations from genetic, psychosocial, operational and ethical points of view were debated. For these considerations, it was assumed that current developments in genetic testing and Internet possibilities mean that, now, all donors are potentially identifiable by their offspring, so no distinction was made between anonymous and non-anonymous donation. Genetic considerations did not lead to restrictive limits (indicating that up to 200 offspring or more per donor may be acceptable except in isolated social-minority situations). Psychosocial considerations on the other hand led to proposals of rather restrictive limits (10 families per donor or less). Operational and ethical considerations did not lead to more or less concrete limits per donor, but seemed to lie in-between those resulting from the aforementioned ways of viewing the issue. In the end, no unifying agreed figure could be reached; however the consensus was that the number should never exceed 100 families. The conclusions of the group are summarized in three recommendation

For commercial re-use, please contact [email protected] question: What information and support should be offered to donors, intended parents and donor-conceived people, in general and in consideration of the availability of direct-to-consumer genetic testing and matching services? Summary answer: For donors, intended parents and donor-conceived offspring, recommendations are made that cover information needs and informed consent, psychosocial implications and disclosure. What is known already: Trends indicate that the use of donor-assisted conception is growing and guidance is needed to help these recipients/intended parents, the donors and offspring, navigate the rapidly changing environment in which donor-assisted conception takes place. Study design size duration: A working group (WG) collaborated on writing recommendations based, where available, on evidence collected from a literature search and expert opinion. Draft recommendations were published for stakeholder review and adapted where relevant based on the comments received. Participants/materials setting methods: Papers retrieved from PUBMED were included from 1 January 2014 up to 31 August 2020, focusing on studies published since direct-to-consumer genetic testing has become more widespread and accessible. The current paper is limited to reproductive donation performed in medically assisted reproduction (MAR) centres (and gamete banks): donation outside the medical context was not considered. Main results and the role of chance: In total, 32 recommendations were made for information provision and support to donors, 32 for intended parents and 27 for donor-conceived offspring requesting information/support. Limitations reasons for caution: The available evidence in the area of reproductive donation is limited and diverse with regards to the context and types of donation. General conclusions and recommendations are largely based on expert opinion and may need to be adapted in light of future research. Wider implications of the findings: These recommendations provide guidance to MAR centres and gamete banks on good practice in information provision and support but should also be considered by regulatory bodies and policymakers at a national and international level to guide regulatory and legislative efforts towards the protection of donors and donor-conceived offspring. Study funding/competing interests: The development of this good practice paper was funded by European Society of Human Reproduction and Embryology (ESHRE), covering expenses associated with the WG meetings, the literature searches and dissemination. The WG members did not receive any payment. The authors have no conflicts of interest to declare. Disclaimer: This document represents the views of ESHRE, which are the result of consensus between the relevant ESHRE stakeholders and where relevant based on the scientific evidence available at the time of preparation. The recommendations should be used for informational and educational purposes. They should not be interpreted as setting a standard of care, or be deemed inclusive of all proper methods of care nor exclusive of other methods of care reasonably directed to obtaining the same results. They do not replace the need for application of clinical judgement to each individual presentation, nor variations based on locality and facility type. †ESHRE pages content is not externally peer reviewed.

New genetic loci link adipose and insulin biology to body fat distribution.

Body fat distribution is a heritable trait and a well-established predictor of adverse metabolic outcomes, independent of overall adiposity. To increase our understanding of the genetic basis of body fat distribution and its molecular links to cardiometabolic traits, here we conduct genome-wide association meta-analyses of traits related to waist and hip circumferences in up to 224,459 individuals. We identify 49 loci (33 new) associated with waist-to-hip ratio adjusted for body mass index (BMI), and an additional 19 loci newly associated with related waist and hip circumference measures (P < 5 × 10(-8)). In total, 20 of the 49 waist-to-hip ratio adjusted for BMI loci show significant sexual dimorphism, 19 of which display a stronger effect in women. The identified loci were enriched for genes expressed in adipose tissue and for putative regulatory elements in adipocytes. Pathway analyses implicated adipogenesis, angiogenesis, transcriptional regulation and insulin resistance as processes affecting fat distribution, providing insight into potential pathophysiological mechanisms
