1\ Excited to finally share some of my PhD work: OpenSplice! We measured how >590,000 mutations affect exon inclusion across 600 human exons, creating a resource to study splicing regulation, benchmark variant effect predictors, and support variant interpretation.

OpenSplice: the impact of half a million mutations on the alternative splicing of 600 human exons https://www.biorxiv.org/content/10.64898/2026.05.22.727141v1

+1 to perhaps not utopian relabeling the world, but gently moving to directly describing the mutation impact in biophysical terms as destabilizing, aggregation-inducing, interface-destroying, etc.; and the higher level phenotypes as a function of these protein qualities, not of mutations!

I wrote an essay. It’s about gain-of-function mutations. And penguins. Also ion channels, chihuahuas, the film Alien, recycled cardboard, and the Apollonian mind. Oh, and muffins. Thanks to the editors of #GENETICS @genetics-gsa.bsky.social for letting me take some stylistic liberties. 1/2

New Perspective form Rory Maizels & me: "Gene regulatory networks: from correlative models to causal explanations" Gene regulatory networks are supposed to give us mechanistic explanations of development, so why are we drowning in 'hairballs' of statistical correlations? rdcu.be/e7zx7

Gene regulatory networks: from correlative models to causal explanations

Nature Reviews Genetics - In this Perspective, Maizels and Briscoe discuss the limitations of current models of gene regulatory networks and outline solutions to harness data abundance without...

New preprint on technologies to scale up CRISPR screens. We use them to map 665,856 pairwise genetic perturbations and outline a path to comprehensive interaction mapping in human cells. We also introduce an approach for cloning lentiviral libraries with billions of elements.

New preprint from our lab, spearheaded by @maelledaunesse.bsky.social and in collaboration with Diego Villar! In which we ask, can we detect joint signatures suggestive of positive selection on transcriptomes and epigenomes?

We've just released our new preprint! 🐀✨ doi.org/10.1101/2025... How do gene expression and regulation evolve during adaptation? And how can we tell adaptive shifts apart from simple drift? @camilleberthelot.bsky.social 👇 A short thread on what we found in African mole-rats.
