In every civilization, people end up sorted into levels of socio-economic status (SES). We explore the history, present, and future of scientific research on the complicated relationship between SES and DNA in @NatureHumBehav 💰🧬🎓 Link: rdcu.be/efacK Thread below 👇🏽

A single-authored research highlight paper from our PhD student Liyang SONG is out now in Nature Review Genetics. @liyang_song

Around 6,500 years ago, hunter-gatherer communities across Eurasia were settling down and living with livestock — and the animals’ diseases came along for the ride go.nature.com/44Ftutl
‘Genetic Risk Effects on Psychiatric Disorders Act in Sets’, the title of our new preprint on @medrxivpreprint! This huge collaborative effort advances our understanding of psychiatric genetic architecture and emphasizes the importance of looking beyond additive effects. 🧵1/n
Interested in love and mate preferences? Our dataset includes responses from 117,293 participants across 175 countries. You're welcome to use it for your own research! Paper and dataset linked below. @ with amazing collaborators from the large-scale cross-cultural consortium <3
Psychiatric Genetics Beyond Heritability: Q&A with Michel Nivard “We look for genes as a means to an end—biology, epidemiology, and etiology of complex human outcomes.” psychiatrymargins.com/p/psychiatric-…
My first paper using SNP data was really just a description of all the patterns I ran into while cleaning the data: nature.com/articles/ejhg2…
For biological data, if you don't have deep expertise in this low value work called data cleaning, u r lacking a fundamental understanding of the idiosyncrasies of the data. Without this knowledge, it is impossible to seriously model data.
The HLA region is key to human health, but is often excluded in large-scale GWAS. Informing future studies on its influence, @AJHGNews' latest article reports HLA haplotype-based associations across thousands of diseases: bit.ly/4lrJiXT #ASHG @jkpritch

On behalf of the CNV analysis workgroup of the @PGCgenetics I'm pleased to share our latest paper "Psychiatric disorders converge on common pathways but diverge in cellular context, spatial distribution, and directionality of genetic effects" 🧵1/N medrxiv.org/content/10.110…
Investigating potential causal effects of maternal smoking on offspring handedness using a proxy gene-by-environment (GxE) Mendelian randomization design out today: link.springer.com/article/10.100… with Daisy Crick @mendel_random @medland_sarah
New preprint with Guy Sella on the question: what is polygenicity? biorxiv.org/content/10.110…

🔔 LGN Summer Lecture! Wed 16 Jul @ UCL Bloomsbury. @dr_appie (Amsterdam UMC) on “Genetic Architecture of a Social Construct”. ☕ 15:30 coffee | 16:00 talk | 🤝 17:00 networking. Members: check your email for the invite from the LGN mailing list.
Yayy that’s all scicomm talks done! Thank you for hosting me at Amsterdam @dr_appie
🚨New preprint is out! How do genetic effects on complex traits change with age? In this work, we compare different approaches to obtain age-varying genetic effects, and show how design and modeling choices can impact the conclusions we draw. shorturl.at/17snd A thread 🧵
How does art contribute to science? My friend Eliza Wolfson and I 'talked' about this in a comic! I'm preparing some lectures for my trip to NL to talk about visual scicomm and this is such a nice excuse to look back at my body of work rather than just the current deadline.
Delighted to share the preprint on the largest obesity GWAS to date! GWAS from >2 million participants Key: ✳️13% increase in loci discovery ✳️Identified 11 obesity genetic clusters (endotypes) ✳️Obesity management should be as diverse as the condition itself Thread👇
