What next for preimplantation genetic screening (PGS)? Experience with blastocyst biopsy and testing for aneuploidy.
Blastocysts more commonly have a normal karyotype than cleavage-stage embryos do. Moreover, blastocysts have also made a metabolic transition from catabolism and recycling of the oocyte's reserves and resources, processes that fuel the first 3 days of cleavage. Although not all blastocysts are karyotypically equal, it is still to be determined to what extent a mosaic karyotype might be a normal...
متن کاملNext generation sequencing (NGS) strategies for the genetic testing of myopathies
Next generation sequencing (NGS) technologies offer the possibility to map entire genomes at affordable costs. This brings the genetic testing procedure to a higher level of complexity. The positive aspect is the ease to cope with the complex diagnosis of genetically heterogeneous disorders and to identify novel disease genes. Worries arise from the management of too many DNA variations with un...

STUDY QUESTION Can next-generation sequencing (NGS) techniques be used reliably for comprehensive aneuploidy screening of human embryos from patients undergoing IVF treatments, with the purpose of identifying and selecting chromosomally normal embryos for transfer? SUMMARY ANSWER Extensive application of NGS in clinical preimplantation genetic screening (PGS) cycles demonstrates that this met...
متن کاملWhat next for preimplantation genetic screening? Beyond aneuploidy.
Many published papers suggest a favourable impact of preimplantation genetic screening (PGS) on implantation and pregnancy rates, but more recent randomized studies have not confirmed, or could not conclude, that PGS actually improved implantation rates. Team inexperience in embryo screening has been mentioned as the origin of the discrepancies; thus some clinicians allege a need for more power...
