Secondary findings, primary news
What’s the burden of reporting incidental/secondary findings? A study of 700 exome tests found longer pre-test counseling sessions, 55 post-test genetic consultations and to 27 secondary specialized medical evaluations.
ACMG presents new recommendations for reporting secondary findings in clinical exome and genome sequencing, encouraging strong genotype-phenotype correlation.

Do, or not do
A study identified carriers of a germline CDKN2A variant associated with increased risk of pancreatic cancer and malignant melanoma. 73% of them intended to undergo screening following the disclosure, but only 20% followed through. Nearly 80% communicated with their health care provider about the result.

The AI Corner
What would it take for clinicians to adopt AI?
487 pathologists surveyed from 50 countries are overwhelmingly in favor of AI, although they believe it will take 5 (38%) 10 (40%) years to integrate into the diagnostic workflow. 93% would be supportive of AI if it would increase time spent on academic or research pursuits.
npj digital medicine
NLP model provides a diagnosis of both known and unknown pediatric diseases, trained with EHRs from approximately 1.4 million patients. The model achieves high diagnostic accuracy.

This and other fun questions on this DNA quiz.
Researchers examine the separate and combined effects of maternal and fetal genetics on birth weight and future cardio-metabolic health, trying to understand which factors are causal and which are genetic, and ultimately help more babies achieve healthy birth weights.
Who needs twins?
Recovering heritability in a 20k genome study. Finds rare gene variants are responsible for various physical traits and diseases, with an estimated heritability of 79% for height (similar results to twin studies) and 40% for BMI.
Diversity & polygenic
Study finds limited portability of polygenic scores across groups of different genetic ancestries, and even sex or age groups.
Pediatric and neonatal WGS
The case for WGS in infants and children with rare, undiagnosed or genetic diseases.

And, of course, doing it fast matters, and that’s where AI comes in. Interpretation still takes 6 hours in this study, using AI for literature review could speed it up even more.
