The prevalence of genetic predisposition to cancer is greater than initially appreciated, yet most affected individuals remain undiagnosed. Deleterious germline variants in cancer predisposition genes are implicated in 1 in 10 cases of advanced cancer. Next-generation sequencing technologies have made germline and tumor DNA sequencing more accessible and less expensive. Expanded access to clinical genetic testing will improve identification of individuals with genetic predisposition to cancer and provide opportunities to effectively reduce morbidity through precision cancer therapies and surveillance. Cross-disciplinary clinical education in genomic medicine is needed to translate advances in genomic medicine into improved health outcomes.

ABSTRACTAn increasing number of diseases can be offered treatments that are transformative if administered in a timely manner. However, many of these diseases are currently not included in the newborn screening programs because they lack sensitive and specific metabolic biomarkers, and detection of children at increased risk relies on genetic methods. Type 1 diabetes (T1D) constitutes a potential example of such disease.Between April 2018 and November 2020, over 15500 babies were enrolled into ‘INGR1D’ (Investigating Genetic Risk for T1D), a research study to identify newborns with an increased genetic risk of T1D. This project, performed as part of a T1D primary prevention study (the Primary Oral Insulin Trial, POInT), has helped to pioneer the integration of genetic screening into the NHS Newborn Blood Spot Screening Programme (NBSSP) for consenting mothers, without affecting the screening pathway. The use of prospective consent to perform personalised genetic testing on samples obtained through the routine NBSSP represents a novel mechanism for clinical genetic research in the UK and provides a model for further population based genetic studies in the newborn.This project builds on the UK’s role as a world leader in genomic medicine, e.g. through its inception and completion of the 100 000 Genomes Project, and its subsequent ambition to map 5 million further genomes over the next 5 years.Our aim is therefore to describe the methodology used by INGR1D as a way to demonstrate how a successful research and clinical trial tool can be integrated into a national screening programme, with the potential for the tool to be developed to incorporate multiple diseases with genetic markers without altering the screening pathway.

SUMMARYBackground:Advances in DNA sequencing have made gene testing fast and affordable, but adaptation of clinical services to capitalise on this for patient benefit has been slow. Ovarian cancer exemplifies limitations of current systems and potential benefits of increased gene testing. Approximately 15% of ovarian cancer patients have a germline mutation in BRCA1 or BRCA2 (collectively termed ‘BRCA’) and this has substantial implications for their personal management and that of their relatives. However, in most countries implementation of BRCA testing in ovarian cancer has been inconsistent and largely unsuccessful.Methods:We developed a mainstream pathway in which BRCA testing was undertaken by cancer team members after 30 minutes online training. Patients with a mutation were sent a genetic appointment with their results. Cascade testing to relatives was performed via standard clinical genetic procedures.Findings:207 women with ovarian cancer were offered gene testing through the mainstream pathway and all accepted. 33 (16%) had a BRCA mutation. The result informed management of 79% (121/154) women with active disease including 97% (32/33) women with a mutation. All mutation-positive women and ~3.5 relatives per family have been seen in genetics. Patient and clinician feedback was very positive. >95% found the pathway to be simple and effective. The pathway offers considerable reduction in time (~5-fold) and resource requirements (~13-fold) compared to the traditional genetic pathway. We estimate it would deliver £2.6M NHS cost savings per year, and would allow implementation of national testing recommendations with existing infrastructure.Interpretation:Mainstream genetic testing is effective, efficient and patient-centred and offers a mechanism for large-scale implementation of BRCA gene testing in cancer patients. The principles could be applied in many other countries and to many other areas of genomic medicine.

Abstract BACKGROUND Inherited cardiac conditions are a relatively common group of Mendelian diseases associated with ill health and death, often in the young. Research into the genetic causes of these conditions has enabled confirmatory and predictive diagnostic sequencing to become an integral part of the clinical management of inherited cardiomyopathies, arrhythmias, aortopathies, and dyslipidemias. CONTENT Currently, the principle benefit of clinical genetic testing is the cascade screening of family members of patients with a pathogenic variant, enabling targeted follow up of presymptomatic genotype-positive individuals and discharge of genotype-negative individuals to health. For the affected proband, diagnostic sequencing can also be useful in discriminating inherited disease from alternative diagnoses, directing treatment, and for molecular autopsy in cases of sudden unexplained death. Advances in sequencing technology have expanded testing panels for inherited cardiac conditions and driven down costs, further improving the cost-effectiveness of genetic testing. However, this expanded testing requires great rigor in the identification of pathogenic variants, with domain-specific knowledge required for variant interpretation. SUMMARY Diagnostic sequencing has the potential to become an integral part of the clinical management of patients with inherited cardiac conditions. However, to move beyond just confirmatory and predictive testing, a much greater understanding is needed of the genetic basis of these conditions, the role of the environment, and the underlying disease mechanisms. With this additional information it is likely that genetic testing will increasingly be used for stratified and preventative strategies in the era of genomic medicine.

AbstractThe molecular millennium has bestowed clinicians and researchers with the essential tools to identify the underlying genetic substrates for thousands of genetic disorders, most of which are rare and follow Mendelian inheritance patterns. The genetic basis of potentially lethal and heritable cardiomyopathies and cardiac channelopathies has been identified and are now better understood. Genetic testing for several of these heritable conditions has made its transition from discovery through translation and have been commercially available clinical tests for over a decade. Now that clinical genetic testing is available more readily and delivers a disease-specific impact across the triad of medicine – diagnostic, prognostic, and therapeutic – it is important for the community of cardiologists to not only be familiar with the language of genomic medicine but to also be wiser users and even wiser interpreters of genetic testing so that wise decisions can be rendered for those patients and their families being evaluated with respect to the presence or absence of one of these potentially lethal yet highly treatable genetic disorders. The purpose of this review is to provide the reader with a foundational understanding of genetic testing in clinical cardiology. Here, we will present some benefits of genetic testing: indications for either post-mortem genetic testing for the major cardiomyopathies and channelopathies or pre-mortem genetic testing among the decedent’s surviving relatives; the need for careful interpretation of genetic testing results; the importance of genetic counselling; and some points on the ethical and societal implications of genetic testing.

Abstract The legal duty to protect patient confidentiality is common knowledge amongst healthcare professionals. However, what may not be widely known, is that this duty is not always absolute. In the United Kingdom, both the General Medical Council governing the practice of all doctors, as well as many other professional codes of practice recognise that, under certain circumstances, it may be appropriate to break confidentiality. This arises when there is a wider duty to protect the health of others, and when the risk of non-disclosure outweighs the potential harm from breaking confidentiality. We discuss this situation specifically in relation to genomic medicine where relatives in a family may have differing views on the sharing of familial genetic information. Overruling a patient’s wishes is predicated on balancing the duty of care towards the patient versus protecting their relative from serious harm. We discuss the practice implications of a pivotal legal case that concluded recently in the High Court of Justice in England and Wales, ABC v St Georges Healthcare NHS Trust & Ors. Professional guidance is already clear that genetic healthcare professionals must undertake a balancing exercise to weigh up contradictory duties of care. However, the judge has provided a new legal weighting to these professional duties: ‘The scope of the duty extends not only to conducting the necessary balancing exercise but also to acting in accordance with its outcome’ [1: 189]. In the context of genomic medicine, this has important consequences for clinical practice.
