Liminality between direct and family-mediated contact in the communication of genetic information to at-risk relatives.

From the article: "Ever since genetic test results have been able to be reported, questions have arisen regarding their implications for genetic relatives. Alongside the proband in whom the initial diagnosis is made, family members often also have an interest in the information. Being informed allows an at-risk relative to consider genetic counseling and testing, and to act in advance to prevent or mitigate future morbidity. Indeed, supporting patients to communicate risk information to their relatives is now considered as a key aspect for maximizing the benefits of genomic medicine. "

Strategies to improve implementation of cascade testing in hereditary cancer syndromes: a systematic review
J Chiang et al, NPJ Genomic Medicine, April 5, 2024

From the abstract: " Despite growing efforts targeted at improving cascade testing uptake, current literature continues to reflect poor rates of uptake, typically below 30%. This study aims to systematically review current literature on intervention strategies to improve cascade testing, assess the quality of intervention descriptions and evaluate the implementation outcomes of listed interventions. This systematic review shows that most interventions have demonstrated success in improving cascade testing uptake. Uptake of cascade testing was highest with delivery arrangement (68%). However, the quality of description of interventions and assessment of implementation outcomes are often suboptimal, hindering their replication and implementation downstream."

Secondary use of genomic data: patients’ decisions at point of testing and perspectives to inform international data sharing
M Martyn et al, EJHG, March 25, 2024

From the abstract: "International sharing of genomic data files arising from clinical testing of patients is essential to further improve genomic medicine. Whilst the general public are reluctant to donate DNA for research, the choices patients actually make about sharing their clinical genomic data for future re-use (research or clinical) are unknown. We ascertained the data-sharing choices of 1515 patients having genomic testing for inherited conditions or cancer treatment from clinical consent forms. "

Genomic analysis of 116 autism families strengthens known risk genes and highlights promising candidates
M Viggiano et al, NPJ Genomic Medicine, March 22, 2024

From the abstract: "Autism spectrum disorder (ASD) is a complex neurodevelopmental condition with a strong genetic component in which rare variants contribute significantly to risk. We performed whole genome and/or exome sequencing (WGS and WES) and SNP-array analysis to identify both rare sequence and copy number variants (SNVs and CNVs) in 435 individuals from 116 ASD families. We identified 37 rare potentially damaging de novo SNVs (pdSNVs) in the cases (n?=?144). "
