🚀 We are introducing PerturbPair (with Taka Kudo) — a platform that combines parallel Perturb-seq and optical pooled screening (PerturbView) in primary cells to systematically map at massive scale how genetic perturbations reshape cellular states across modalities. www.biorxiv.org/content/10.6...

A herculean effort by many, but esp. the first three authors: Ujjwal Rathore, Eli Dugan, and Hunter Thornton working in the Krogan and Marson labs, with a veritable army of collaborators from HARC (harc.ucsf.edu) and beyond. Press release: gladstone.org/news/scienti... (inc. paper link)

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

I'm just delighted to announce our new preprint on genome-scale perturb-seq in CD4+ T cells. We learned both general lessons about the power of perturb-seq, and specific lessons about T cell biology. Led by amazing postdocs Emma Dann and Ronghui Zhu, with my wonderful collaborator Alex Marson.

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

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🧵:

A really nice paper by @drghawkes.bsky.social et al. argues that rare and common genetic associations converge on the same genes. While this seems at odds with our recent work about how burden tests and GWAS prioritize different genes, our results agree (🧬🧪🧵 1/6) www.biorxiv.org/content/10.1...

Beautifully elegant work on integrating LoF, GWAS & Perturb-seq data to build causal paths from regulators to genes / programs to phenotype. And it didn't require a foundational virtual cell model (well almost ... gene & protein embeddings r used in GeneBayes)! 😜

Really nice work. And they chose one of my favorite traits to model: mean corpuscular hemoglobin. Allows me to reuse one of my figures from a few weeks ago on a gene as old as eukaryotes, mitoferrin, which is needed to move iron into mitochondria. @jkpritch.bsky.social

Thank you Jonathan for these fantastic threads about our recent work! We dove into how we can model the gene regulatory architecture of complex traits with 1) Gene effects from LoF burden tests and 2) Perturb-seq.
