Why do schizophrenia GWAS signals look so flat across the genome? In our recent preprint, we explored why psychiatric disorders — and, more broadly, brain-related traits involving the central nervous system — appear to have unusual genetic architectures. 🧵1/n

How well does TWAS estimate a gene’s direction of effect on a trait? We think of this as an important stress-test for the accuracy of TWAS. In a new pre-print, we find that TWAS gets the sign wrong around 20-30% of the time! doi.org/10.64898/202... 1/n
High false sign rates in transcriptome-wide association studies
Transcriptome-wide association studies (TWAS) are widely used to identify genes involved in complex traits and to infer the direction of gene effects on traits. However, despite their popularity, it r...

GWAS has been an incredible discovery tool for human genetics: it regularly identifies *causal* links from 1000s of SNPs to any given trait. But mechanistic interpretation is usually difficult. Our latest work on causal models for this is out yesterday: www.nature.com/articles/s41... A short🧵:

@hakha.bsky.social and I wrote a Research Briefing (with a lay summary + "behind the scenes") of our paper on how genes are prioritized by GWAS and rare variant burden tests. 🧬🧪 www.nature.com/articles/d41...
How do genetic association studies rank genes?
Genome-wide association studies and rare-variant burden tests reveal complementary aspects of trait biology.

Excited to see a home for MCP servers in bioinformatics emerge! The community needs a central hub for developing MCP servers for key bioinfo tools. At @scverse.bsky.social we're contributing to this effort - can't wait to share what we're building
BioContextAI is a community hub for agentic biomedical systems - @puellesv.bsky.social @biocontext.ai go.nature.com/3JmqKux
I'm recruiting a postdoc for my group (based in beautiful Eugene, OR). Please get in touch if you're interested, esp if you'd like to chat at #ASHG25!
We'll primarily work at the intersection of statistical and population genetics, and we also have active projects related to the ethical and social implications of human genetics (ELSI). Please get in touch if that's a combination that sounds interesting to you!

I posted a couple days ago about our new paper on building causal graphs from genetic associations + Perturb-seq. Here I want to expand on the value of using DIRECTIONAL information contained in LoF burden tests.🧵 [work led by @minetoota.bsky.social ] bsky.app/profile/jkpr...
GWAS provides a unique tool in human biology as it can establish causal links from variants to trait. But interpretation is difficult as most effects flow through (unobserved) gene regulatory networks. Can we gain insight by linking to modern Perturb-seq data? www.biorxiv.org/content/10.1...
@minetoota.bsky.social set the groundwork for many ongoing projects in @jkpritch.bsky.social and Marson lab. Great to see this out!
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 🧵
