1/4 Thrilled to be sharing new work published today in Nature describing the third wave of results from the PGC Cross-Disorder Group. This reflects a massive group effort to examine shared and unique genetic signal across >1 million cases for 14 psychiatric disorders. www.nature.com/articles/s41...
First time on Bsky and first big announcement!
I am excited to announce that our new study explaining the missing heritability of many phenotypes using WGS data from ~347,000 UK Biobank participants has just been published in @Nature.
Our manuscript is here: www.nature.com/articles/s41....
🚨 New paper out! In a collaboration across MVP, FinnGen & UK Biobank, we conducted a phenome-wide study of sex chromosome trisomies (SCT) in 1.5M participants. Findings reveal shared disease risks across SCT. 🔗 www.sciencedirect.com/science/arti...
“What an odd thing“ wrote Oliver Sacks “to see an entire species playing with listening to meaningless tonal patterns, preoccupied for much of their time by what they call ‘music’...“. Our new paper, led by ace student @giacomobignardi.bsky.social, unpacks this puzzle from a genetic perspective. 🧪
Out today, our method for comparing multivariate genetic architecture across groups of people, called Genomic Structural Invariance: www.nature.com/articles/s41...

New preprint🌍 Our trans-ancestry GWAS in UK Biobank uncovers novel risk loci for major depression, improving genetic insights across populations. 🔗: www.medrxiv.org/content/10.1... @madhurbsingh.bsky.social @gentyae.bsky.social @pbb319.bsky.social timbigdeli.bsky.social @roseannpeterson.bsky.social
Many thanks to all of the collaborators and funders (esp
@wellcometrust.bsky.social & @ukri.org) who made this DNA methylome-wide study of antidepressant exposure possible www.nature.com/articles/s41...
Excited to share a couple of new items (links below):
1. Our work on gene-environment interactions in the UKBiobank is up at the American Journal of Human Genetics
2. Our work on modeling ancient human population size history is up at Molecular Biology and Evolution
🚨NEW PAPER! Together with Wuno Akingbuwa (@wonuola.bsky.social) we developed a way to estimate non-linear genetic correlations. It didnt sit well with us that known non-linear relations (e.g. BMI and MDD with a famous U shaped ) are poorly captured in statistical genetics. 🧵
Incredibly proud to see our latest work out in Nature Genetics: www.nature.com/articles/s41...
Here we share our FLAMES framework, which predicts the effector genes in GWAS loci with state-of-the-art precision🔥
Special thanks to @daniposthu.bsky.social
A full thread describing findings below!
New paper! Led by Kirsten J. M. van Hooijdonk & Jacqueline Vink, this study finds no bidirectional causal link between diet/physical activity & depression/anxiety using triangulation. No strong causal evidence! @zoereed.bsky.social @madhurbsingh.bsky.social
📖 doi.org/10.1017/S003...
Nice paper showing ~1/540 people have a sex chromosome trisomy from 3 large biobanks (UKB, FinnGen, MVP) comprising 1.5 million individuals along with their phenotypic impact.

Genetic correlations between MDD and each neuroticism cut point. The line of best fit is shown, based on a linear regression model, with parameters estimated using generalized least squares (GLS).
Standardized results (with standard errors) for two-factor genomic structural equation model as estimated using GenomicSEM software.
Standardized results (with standard errors) for three-severity factor genomic structural equation model as estimated using GenomicSEM software.
Are mental disorders extreme manifestations of continuous traits or genetically distinct entities? We present Genomic Taxometric Analysis of Continuous and Case-Control data (GTACCC) for evaluating genetic continuity and differentiation of traits across the severity spectrum. Tweetorial coming soon.
Modern GWAS can identify 1000s of significant hits but it can be hard to turn this into biological insight. What key cellular functions link genetic variation to disease?
I'm very excited to present our new work combining associations and Perturb-seq to build interpretable causal graphs! A 🧵

New here? or logged back in recently? Find your old friends in statistical and psychiatric genetics in this starter pack, ill try to update frequently, let me know if you want to be added: go.bsky.app/9643dwo
@ent3c.bsky.social suggested we need a behaviour genetics starter pack, let me know who to add!
I couldn't spot a starter pack for rare disease / clinical genomics, so I started one: go.bsky.app/SUWZ9Hw
Very much a work in progress, and biased by who I have already found here, so please suggest people to add! Self-nominations encouraged.

e.g., if you were using mxPath() to specify a path, you'd set free=TRUE and then specify some lbound and ubound values. Of course, you'd need a rationale to constrain the parameter within that range.
