Combined population genomic screening for three high-risk conditions in Australia: a modelling study
P Lacaze et al, e Clin Medicine, November 2023

From the abstract: "This modeling study assessed the impact of offering combined genomic screening for hereditary breast and ovarian cancer, Lynch syndrome and familial hypercholesterolaemia to all young adults in Australia, compared with the current practice of clinical criteria-based testing for each condition separately. Our findings suggest that offering combined genomic screening for high-risk conditions to young adults would be cost-effective in the Australian public healthcare system, at currently realistic testing costs.

Ten Years of Incidental, Secondary, and Actionable Findings.
Sharon Plon et al. N Engl J Med 2023 11 (19) 1813-1814

From the paper: "The ACMG has highlighted the fact that the ACMG SF gene lists were not designed to be implemented for population screening outside of research. However, many of the genes that have an effect on life span are also considered to be “tier 1” by the Centers for Disease Control and Prevention; knowledge of their status could have a positive effect on population health.

Actionable Genotypes and Their Association with Life Span in Iceland.
Brynjar O Jensson et al. N Engl J Med 2023 11 (19) 1741-1752

From the abstract: " In 2021, the American College of Medical Genetics and Genomics (ACMG) recommended reporting actionable genotypes in 73 genes associated with diseases for which preventive or therapeutic measures are available. Evaluations of the association of actionable genotypes in these genes with life span are currently lacking. In this study, we found that approximately 1 in 25 Icelanders carried an actionable genotype and that carrying such a genotype was associated with a reduced life span."

Risk perception and intended behavior change after uninformative genetic results for adult-onset hereditary conditions in unselected patients.
Nandana D Rao et al. Eur J Hum Genet 2023 9

From the abstract: "Overall, 2761 people received uninformative results and 1352 (49%) completed survey items. Respondents averaged 41 years old, 62% were female, and 56% were Non-Hispanic Asian. Results from the FACToR instrument showed mean (SD) scores of 0.92 (1.34), 7.63 (3.95), 1.65 (2.23), and 0.77 (1.50) for negative emotions, positive emotions, uncertainty, and privacy concerns, respectively, suggesting minimal psychosocial harms from genetic screening. Overall, 12.2% and 9.6% of survey respondents believed that their risk of cancer or heart disease, respectively, had changed after receiving their uninformative genetic screening results. Further, 8.5% of respondents planned to make healthcare changes and 9.1% other behavior changes. "
