Genetic regulation of OAS1 nonsense-mediated decay underlies association with COVID-19 hospitalization in patients of European and African ancestries.
Banday A Rouf et al. Nature genetics 2022 7

In our analysis of patients of European (n?=?2,249) and African (n?=?835) ancestries with hospitalized versus nonhospitalized COVID-19, the risk of hospitalized disease was associated with a common OAS1 haplotype, which was also associated with reduced severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) clearance in a clinical trial with pegIFN-?1. Bioinformatic analyses and in vitro studies reveal the functional contribution of two associated OAS1 exonic variants comprising the risk haplotype. Our results provide insight into molecular mechanisms through which early treatment with interferons could accelerate SARS-CoV-2 clearance and mitigate against severe COVID-19.

The omicron subvariant dominating U.S. COVID-19 cases is more vaccine-resistant
A Archie, NPR, July 15, 2022

The BA.5 omicron subvariant, which is now the most prevalent coronavirus strain in the United States, is four times more resistant to COVID-19 vaccines, according to a new study. The strain, which is considered "hypercontagious," according to the Mayo Clinic, is more defiant against messenger RNA vaccines, which include Pfizer and Moderna. The BA.5 strain represented 65% of cases from July 3 to 9, according to data from the CDC.

Experiences of individuals with a variant of uncertain significance on genetic testing for hereditary cancer risks: a mixed method systematic review.
Gould Danielle et al. Journal of community genetics 2022 7

A total of 18 studies met the inclusion criteria. Studies included in this review identified a range of emotional reactions to a VUS result, a general lack of understanding of a VUS result and its implications, frustration with a lack of healthcare provider knowledge, and a need for clear communication with healthcare providers.

Variation among DNA banking consent forms: points for clinicians to bank on.
Huang Samuel J et al. Journal of community genetics 2022 7

The objectives of this study were to assess the level of consistency of current clinical DNA banking consent forms with the American Society of Human Genetics (ASHG) and the American College of Medical Genetics and Genomics (ACMG) guidance and to explore variation among the forms. The content analysis matrix included key points identified from the ASHG and ACMG documents (including benefits/risks, sample storage, access, disposition, and communication).

Cost-effectiveness frameworks for comparing genome and exome sequencing versus conventional diagnostic pathways: A scoping review and recommended methods.
Ferket Bart S et al. Genetics in medicine : official journal of the American College of Medical Genetics 2022 7

We recommend the following considerations for each clinical scenario. For prenatal testing, performing comparative analyses of costs of ES strategies and postpartum care, as well as genetic diagnoses and pregnancy outcomes. For early diagnosis in pediatrics, modeling quality-adjusted life years (QALYs) and costs over =20 years for rapid turnaround GS/ES. For hereditary cancer syndrome testing, modeling cumulative costs and QALYs for the individual tested and first/second/third-degree relatives. For tumor profiling, not restricting to treatment uptake or response and including QALYs and costs of downstream outcomes. For screening, modeling lifetime costs and QALYs and considering consequences of low penetrance and GS/ES reanalysis.
