In the ongoing discussion about the risks of reproductive human germline modification, scant attention has been paid to whether it could be reconciled with theories of psychological well-being. Even if safety and feasibility challenges could be overcome and germline engineering technology could be implemented in ways that avoid exacerbating social inequality, we would still have to question whether germline modification would promote circumstances that lead to better psychological experiences for parents, society, and the genetically edited person. This paper posits that germline engineering would produce expectations of being able to control the manifestation of an individual’s characteristics, which will inevitably be upset by our limited understanding of how genes interact with each other and with the environment. Drawing on self-discrepancy and relative deprivation theories, it is suggested that both editing and being edited could lead to unmet expectations and thus negative emotional states that would offset benefits of successful intended genetic changes.

STUDY QUESTION: What factors are associated with decision regret and anxiety following preimplantation genetic testing for aneuploidy (PGT-A)? SUMMARY ANSWER: The majority of patients viewed PGT-A favourably regardless of their outcome; although patients with negative outcomes expressed greater decision regret and anxiety. WHAT IS KNOWN ALREADY: PGT-A is increasingly utilized in in vitro fertilization (IVF) cycles to aid in embryo selection. Despite the increasing use of PGT-A technology, little...

The announcement of He Jiankui’s germline editing of human embryos has been followed by a torrent of almost universal criticism of the claim on scientific and ethical grounds. That criticism is warranted. There is little room for anything other than vociferous condemnation of He's announcement. Presenting the results of groundbreaking work by press conference and YouTube is not science. The issue now is not whether the work supporting the claims reported from China was done in an ethical manner....

To date, epimutations reported in man have been somatic and erased in germlines. Here, we identify a cause of the autosomal recessive cblC class of inborn errors of vitamin B12 metabolism that we name “epi-cblC”. The subjects are compound heterozygotes for a genetic mutation and for a promoter epimutation, detected in blood, fibroblasts, and sperm, at the MMACHC locus; 5-azacytidine restores the expression of MMACHC in fibroblasts. MMACHC is flanked by CCDC163P and PRDX1, which are in the opposi...

CRISPR–Cas9 genome editing is used to induce a DNA repair response and correct a disease-causing heterozygous mutation in human embryos with reduced mosaicism and preferential repair using the wild-type copy of the gene.

Summary Bacterial CRISPR-Cas systems utilize sequence-specific RNA-guided nucleases to defend against bacteriophage infection. As a countermeasure, numerous phages are known that produce proteins to block the function of class 1 CRISPR-Cas systems. However, currently no proteins are known to inhibit the widely used class 2 CRISPR-Cas9 system. To find these inhibitors, we searched cas9 -containing bacterial genomes for the co-existence of a CRISPR spacer and its target, a potential indicator for ...

The term “CRISPR” has gained a lot of attention recently as a result of a debate among scientists about the possibility of genetically modifying the human germ line and the ethical implications of doing so. However, CRISPR is not just a method to edit the genomes of embryonic cells, as the public discussion might have implied; it is a powerful, efficient, and reliable tool for editing genes in any organism, and it has garnered significant attention and use among biologists for a variety of purpo...

Genome editing tools such as the clustered regularly interspaced short palindromic repeat (CRISPR)-associated system (Cas) have been widely used to modify genes in model systems including animal zygotes and human cells, and hold tremendous promise for both basic research and clinical applications. To date, a serious knowledge gap remains in our understanding of DNA repair mechanisms in human early embryos, and in the efficiency and potential off-target effects of using technologies such as CRISP...

Objectives. Parents’ perceptions of their adult children’s successes (or lack thereof) may be associated in different ways with discrete negative emotions (e.g., guilt, anger, disappointment, and worry). Furthermore, mothers and fathers may vary in their reactions to children’s success in different domains. Method. Participants included 158 mothers and fathers from the same families (N = 316) and their adult child. Mothers and fathers evaluated their adult children’s successes in (a) career and ...

Communicating genetic risk information in ways that maximize understanding and promote health is increasingly important given the rapidly expanding availability and capabilities of genomic technologies. A well-developed literature on risk communication in general provides guidance for best practices, including presentation of information in multiple formats, attention to framing effects, use of graphics, sensitivity to the way numbers are presented, parsimony of information, attentiveness to emo...
