I-20: Towards The Transparent Embryo: Dynamics and Ethics of Comprehensive Preimplantation Genetic Screening

چکیده مقاله:
Background: To study the ethical aspects of comprehensive preimplantation genetic screening (PGS) through microarrays and whole genome sequencing Materials and Methods: In order to pinpoint ethical issues regarding comprehensive embryo screening we have first investigated the technical and moral issues by organizing a campus meeting with experts and by a literature study. Subsequently we have investigated the opinions of professionals regarding the possible introduction of comprehensive screening techniques in the IVF clinic and the ethical implications in a focus group study. We have also investigated the feasibility and analytical and clinical validity and clinical utility of whole genome sequencing for embryo selection. Finally, based on our previous conclusions, we have performed a theoretical reflection on professional responsibility regarding the use of micro-arrays in order to perform comprehensive chromosome screening. Results: The increasing complexity and amount of information yielded by comprehensive testing techniques will lead to challenges to the principle of reproductive autonomy and the right of the child to an open future. Furthermore, it may complicate the responsibility of the clinician regarding the welfare of the future child, and may lead to conflicts with prospective parents. Moreover, the analytic and clinical validity and the clinical utility of whole genome sequencing as a tool for embryo selection is unproven. An alternative testing approach is preconception carrier screening for a number of disorders, combined with targeted PGD for couples at high risk. This may avoid some of the ethical problems of comprehensive embryo screening. Obviously, the ethics of this alternative needs further ethical scrutiny as well. Moreover, there is a need for studies querying the opinions of infertile couples undergoing IVF/PGS regarding the desirability of embryo screening beyond aneuploidy. Conclusion: The introduction of comprehensive screening techniques for embryo selection is premature at best and calls for further ethical reflection that is grounded in empirical work.

Dynamics and ethics of comprehensive preimplantation genetic testing: a review of the challenges.
BACKGROUND Genetic testing of preimplantation embryos has been used for preimplantation genetic diagnosis (PGD) and preimplantation genetic screening (PGS). Microarray technology is being introduced in both these contexts, and whole genome sequencing of blastomeres is also expeted to become possible soon. The amount of extra information such tests will yield may prove to be beneficial for embry...
متن کاملPreimplantation Genetic Screening
In the last 30 years, genetic testing techniques have been developed to identify chromosomally normal embryos in vitro, thereby potentially increasing the proportion of successful cycles with elective single-embryo transfer, and minimizing twin-pregnancy complications and miscarriages. This testing is termed "pre-implantation genetic screening" (PGS), in contrast to preimplantation genetic diag...

Sir, We read with great interest a recent systematic review by Lee et al. published inyour journal evaluating the clinical effectivenessofpreimplantation genetic diagnosis for aneuploidy in all 24 chromosomes (PGD-A) (Lee et al., 2015). The authors conclude that, for the time being, the role for PGD-A remains uncertain regarding its clinicaland costeffectiveness. In our opinion, a number of obs...

Introduction The development of the Human Genome Project has raised many privacy concerns regarding the use of genetic screening in employment, health premium coverage, and data-mining. Moreover, what causes extreme concern is the lack of direct government regulation addressing the use of such information. There is no law directly addressing this issue or who should be given access to this info...
متن کاملEthics and the future of preimplantation genetic diagnosis.
The future growth of preimplantation genetic diagnosis (PGD) will depend on refinements in genetic knowledge and genetic analysis of blastomeres. Equally important, however, is an acceptance of the ethical legitimacy of parents using technologies to select genetic traits of offspring. Objections based on embryo status, the giftedness of reproduction, eugenics, and protecting the child's welfare...
