Can anyone recommend a good immigration lawyer?

Happy to see this online! Having an extra sex chromosome really challenge the binary definition of sex based on XX and XY. So it is not only a medical, but also an important societal question.

Grateful for this terrific commentary by @tomonroe.bsky.social in @jclinical-invest.bsky.social on our paper that is out in final print format today: www.jci.org/articles/vie... Please check it out: www.jci.org/articles/vie...

Our new AJHG paper is online. We develop a new TWAS tool that uses local-ancestry information to improve power of gene mapping in admixed samples. Lead author Taylor Head (now at MD Anderson) did a phenomenal job spearheading this work!

A final point about trust. Herasight has apparently partnered with Heliospect Genomics, founded by self-described eugenicist Jonathan Anomaly (a member of both companies). Anomaly and Heliospect were profiled last year by Hope Not Hate: investigations.hopenothate.org.uk/superbaby-fa...

We have 2-3 group leader positions opening @fimm-uh.bsky.social !! We are looking for outstanding candidates in human genetics and precision medicine. This time we have a focus on population health data science. E.g. AI for EHR/health data        Generous starting package 💰 shorturl.at/FAk6n

Super excited to see this out. What started as some math in a grant in 2020, to a student deciding to take this on in 2022, to published in 2025. These things can take time and patience is key!

IDH mutations are some of the most informative prognostic markers for #glioma. Our small, proof-of-concept study shows that #multimodal classifiers that include #polygenic risk scores can improve pre-operative molecular subtyping: www.nature.com/articles/s41... 🧠🧬 @stanford-cancer.bsky.social

I'm excited to share our latest work, now out in #PLOSGenetics! If you feel limited by linear models in TWAS or PWAS but don't think you can switch to nonlinear methods due to a lack of individual-level phenotype data, this paper is for you. 🔗 journals.plos.org/plosgenetics... Thread below 👇 (1/6)

Hating on “Big Pharma”? Cool, it’s a $1.6 trillion regulated industry. But hang on…the $6.3 trillion wellness industry sells you mushroom tea, dewormers, crash diets, and alkaline water—no regulations, no oversight. But hey, it’s ‘natural,’ right?

3/n Genetic correlation is straightforward but remember HLA - largely impacting T1D & other AIDs - is excluded by LDSC. If genetic correlation is a genome-wide non-HLA measurement, how can we get HLA back into the game? We built a within-sample HLA PGS with weighted ridge classifiers in FinnGen.
