A framework for the evaluation and reporting of incidental findings in clinical genomic testing
CM Brown et al, EJHG, April 2, 2024

From the abstract: "Herein we describe a framework developed to guide the evaluation and return of IFs encountered in probands undergoing clinical genome sequencing (cGS). The framework prioritizes clinical significance and actionability of IFs and follows a stepwise approach with stopping points at which IFs may be recommended for return or not. Over 18 months, implementation of the framework in a clinical laboratory facilitated the return of actionable IFs in 37 of 720 (5.1%) individuals referred for cGS. "

Past as Prologue: Predicting Potential Psychosocial–Ethical Burdens of Positive Newborn Screens as Conditions Propagate
LW ush et al, IJNS, February 2024

From the abstract: "We look to the past as prologue for guidance in predicting and circumventing potential psychosocial–ethical challenges, including those that may influence the attachment process for some parents. We consider the evolution of bioethics and developmental psychology as they intersect with newborn screening while exploring potential implications of positive findings, be they false positives, true positives, or secondary as well as incidental findings. We reflect on navigating the complex landscape that may be significantly impacted by variable phenotypes, the age of onset, and uncertain prognoses, mindful of the diagnostic odyssey continuum. "

Informed consent for whole genome sequencing in mainstream clinics: logistical constraints and possible solutions
A Chaouch et al, EJHG, January 4, 2024

From the article: "The complexity of WGS, the range of possible incidental findings, the inevitable uncertainties, and the often limited understanding about genomics by patients, their family, and sometimes by mainstream clinicians can make informed consent difficult to achieve. Some have argued that an excess of information can be a deterrent for patients, as it may lead to difficulties in ensuring valid consent and hinder access to potentially valuable investigations and treatments. However, it is important that enough information is provided to bring patients’ and families’ hopes and expectations into a realistic alignment with the likely results of WGS. "

Secondary (additional) findings from the 100,000 Genomes Project: disease manifestation, healthcare outcomes and costs of disclosure
J Nolan et al, Genetics in Medicine, December 19, 2023

From the abstract: "The UK 100,000 Genomes Project offered participants screening for additional findings (AFs) in genes associated with familial hypercholesterolemia (FH) or hereditary cancer syndromes including breast/ovarian cancer (HBOC), Lynch, familial adenomatous polyposis, MYH-associated polyposis, multiple endocrine neoplasia, von Hippel-Lindau. Here we report disclosure processes, manifestation of AF-related disease, outcomes and costs. "
