A cross-professional competency framework for communicating genomic results.

To ensure genomic medicine is delivered safely and effectively, it is crucial that healthcare professionals are able to understand and communicate genomic results. This Education Innovation describes a nationally agreed, cross-professional competency framework outlining the knowledge, skills and behaviors required to communicate genomic results. Using principles of the nominal group technique, consensus meetings with clinical, scientific and educational experts identified six stages in the return of results process, drafted and iterated competencies. Competencies were then mapped across three levels to acknowledge different degrees of experiences and scopes of practice. The framework was open for consultation with healthcare professionals and patient communities before being published. The finalized framework includes six core competency statements required to communicate genomic results. This framework is designed to be a guide for best practice and a developmental tool to support individuals and organizations. It can be used by healthcare professionals, such as genetic counselors, to identify individual learning needs or to structure the development of training for other healthcare professionals who are increasingly involved in requesting and returning results for genomic tests.

The implementation of large-scale genomic screening or diagnostic programmes: A rapid evidence review.

Genomic healthcare programmes, both in a research and clinical context, have demonstrated a pivotal opportunity to prevent, diagnose, and treat rare diseases. However, implementation factors could increase overall costs and affect uptake. As well, uncertainties remain regarding effective training, guidelines and legislation. The purpose of this rapid evidence review was to draw together the available global evidence on the implementation of genomic testing programmes, particularly on population-based screening and diagnostic programmes implemented at the national level, to understand the range of factors influencing implementation. This review involved a search of terms related to genomics, implementation and health care. The search was limited to peer-reviewed articles published between 2017-2022 and found in five databases. The review included thirty articles drawing on sixteen countries. A wide range of factors was cited as critical to the successful implementation of genomics programmes. These included having policy frameworks, regulations, guidelines; clinical decision support tools; access to genetic counselling; and education and training for healthcare staff. The high costs of implementing and integrating genomics into healthcare were also often barriers to stakeholders. National genomics programmes are complex and require the generation of evidence and addressing implementation challenges. The findings from this review highlight that there is a strong emphasis on addressing genomic education and engagement among varied stakeholders, including the general public, policymakers, and governments. Articles also emphasised the development of appropriate policies and regulatory frameworks to govern genomic healthcare, with a focus on legislation that regulates the collection, storage, and sharing of personal genomic data.

Newborn Screening by Genomic Sequencing: Opportunities and Challenges.

Newborn screening for treatable disorders is one of the great public health success stories of the twentieth century worldwide. This commentary examines the potential use of a new technology, next generation sequencing, in newborn screening through the lens of the Wilson and Jungner criteria. Each of the ten criteria are examined to show how they might be applied by programmes using genomic sequencing as a screening tool. While there are obvious advantages to a method that can examine all disease-causing genes in a single assay at an ever-diminishing cost, implementation of genomic sequencing at scale presents numerous challenges, some which are intrinsic to screening for rare disease and some specifically linked to genomics-led screening. In addition to questions specific to routine screening considerations, the ethical, communication, data management, legal, and social implications of genomic screening programmes require consideration.

A systematic analysis of splicing variants identifies new diagnoses in the 100,000 Genomes Project.

BACKGROUND: Genomic variants which disrupt splicing are a major cause of rare genetic diseases. However, variants which lie outside of the canonical splice sites are difficult to interpret clinically. Improving the clinical interpretation of non-canonical splicing variants offers a major opportunity to uplift diagnostic yields from whole genome sequencing data. METHODS: Here, we examine the landscape of splicing variants in whole-genome sequencing data from 38,688 individuals in the 100,000 Genomes Project and assess the contribution of non-canonical splicing variants to rare genetic diseases. We use a variant-level constraint metric (the mutability-adjusted proportion of singletons) to identify constrained functional variant classes near exon-intron junctions and at putative splicing branchpoints. To identify new diagnoses for individuals with unsolved rare diseases in the 100,000 Genomes Project, we identified individuals with de novo single-nucleotide variants near exon-intron boundaries and at putative splicing branchpoints in known disease genes. We identified candidate diagnostic variants through manual phenotype matching and confirmed new molecular diagnoses through clinical variant interpretation and functional RNA studies. RESULTS: We show that near-splice positions and splicing branchpoints are highly constrained by purifying selection and harbour potentially damaging non-coding variants which are amenable to systematic analysis in sequencing data. From 258 de novo splicing variants in known rare disease genes, we identify 35 new likely diagnoses in probands with an unsolved rare disease. To date, we have confirmed a new diagnosis for six individuals, including four in whom RNA studies were performed. CONCLUSIONS: Overall, we demonstrate the clinical value of examining non-canonical splicing variants in individuals with unsolved rare diseases.

Developing a National Newborn Genomes Program: An Approach Driven by Ethics, Engagement and Co-design.

The transformative potential of whole genome sequencing (WGS) as a diagnostic tool in healthcare has been demonstrated by initiatives including the 100,000 Genomes Project and is now offered to certain patients in the National Health Service (NHS) in England. Building on these foundations, the utility of WGS in the newborn period can now be explored. Genomics England is working in partnership with NHS England and NHS Improvement and other healthcare, patient and public interest groups to design a research program embedded in the NHS to explore the potential challenges and implications of offering WGS in all newborns. The program will aim to: 1) evaluate the feasibility, utility and impact on the NHS of screening for childhood-onset rare actionable genetic conditions; 2) understand how, with consent, genomic and healthcare data could be used to enable research to develop new diagnostics and treatments; and 3) explore the implications of storing an individual's genome for use over their lifetime. Recognizing the important practical, scientific and ethical questions that we must explore in dialogue with the public and experts, we are taking a collaborative, evidence-based and ethically deliberate approach to designing the program. An iterative co-design process including a nationwide public dialogue has identified emergent themes and ethical considerations which are the focus of the program's design. These themes will be further developed through continued engagement with healthcare professionals, researchers, ethics experts, patient groups and the public, with an ongoing commitment to embedding ongoing ethics research and co-design into the delivery of the program.

A nationally agreed cross-professional competency framework to facilitate genomic testing.

PURPOSE: The study aimed to develop a nationally agreed, cross-professional competency framework outlining the knowledge, skills, and behaviors required to facilitate genomic tests. METHODS: Using principles of the nominal group technique, a consensus meeting with 25 experts mapped themes to an initial framework and voted on areas of inconsistency. A revised framework was open for consultation with health care professionals and patient communities before being published. An evaluation, using an online survey, was conducted to explore early use and factors to facilitate adoption of the framework. RESULTS: The framework identified 8 competencies required to facilitate genomic tests. The evaluation (239 survey responses from health care professionals) indicated that the framework addresses a timely need among users and identified ways to improve awareness and accessibility for different health care professional groups. CONCLUSION: This framework can be used as a guide for best practice by health care professionals who request genomic tests. It can also provide a foundation to identify learning needs and structure training such that conversations about genomic testing can be delivered in a consistent manner across specialties. These competencies can also be used as a reference to evaluate how consent is facilitated in different specialty areas to enhance the responsible delivery of genomic medicine.

Experience with genetic counseling: the adolescent perspective.

Adolescence is a complex period of development that involves creating a sense of identity, autonomy, relationships and values. This stage of adjustment can be complicated by having a genetic condition. Genetic counseling can play an important role in providing information and support to this patient population; however, resources and guidelines are currently limited. In order to appropriately establish genetic counseling approaches and resource development, we investigated the experiences and perspectives of adolescents with a genetic condition with respect to their genetic counseling interactions. Using a qualitative exploratory approach, eleven semi-structured interviews were conducted with adolescents diagnosed with a genetic condition who received genetic counseling between the ages of 12 and 18 years at The Hospital for Sick Children. Transcripts were analyzed thematically using qualitative content analysis, from which three major interrelated themes emerged: 1) understanding the genetic counselor's role; 2) increasing perceived personal control; and 3) adolescent-specific factors influencing adaptation to one's condition. Additionally, a list of suggested tools and strategies for genetic counseling practice were elucidated. Our findings can contribute to the development of an adolescent-focused framework to enhance emerging genetic counseling approaches for this patient population, and can also facilitate the transition process from pediatric to adult care within patient and family-centered contexts.
