Cascade testing for hereditary cancer: comprehensive multigene panels identify unexpected actionable findings in relatives.
Brandie Heald et al. J Natl Cancer Inst 2023 9

From the abstract: "Cascade testing using multigene panels was performed in 3,696 relatives of 7,433 probands. Unexpected PGVs were identified in 230 (6.2%) relatives, including 144 who were negative for the familial PGV but positive for a PGV in a different gene than the proband and 74 who tested positive for the familial PGV and had an additional PGV in a different gene than the proband. Of the relatives with unexpected PGVs, 36.3% would have qualified for different or additional cancer screening recommendations. Limiting cascade testing to only the familial PGV would have resulted in missed, actionable findings for a subset of relatives."

A gene-by-sex interaction contributes to liver disease susceptibility in women
Nature Medicine, October 2, 2023

From the abstract: "Clinical and population-based cohorts revealed an interaction between the inherited PNPLA3 p.I148M variant and female sex in determining liver disease. Transcriptomic and functional studies showed that the mechanism encompasses ERa-dependent upregulation of PNPLA3 in hepatocytes, highlighting a target for precision medicine therapeutics in cisgender women.

Early detection of autism using digital behavioral phenotyping
S Perochon et al, Nature Medicine, October 2, 2023

From the abstract: "Early detection of autism, a neurodevelopmental condition associated with challenges in social communication, ensures timely access to intervention. Autism screening questionnaires have been shown to have lower accuracy when used in real-world settings, such as primary care, as compared to research studies, particularly for children of color and girls. Here we report findings from a multiclinic, prospective study assessing the accuracy of an autism screening digital application (app) administered during a pediatric well-child visit to 475 (17–36 months old) children (269 boys and 206 girls).
