Saturation editing of RNU4-2 reveals distinct dominant and recessive disorders - Nature Saturation genome editing of RNU4-2 identifies the functional and clinical impact of variants across the entire gene and delineates variants that cause a new recessive neurodevelopmental disorder distinct from ReNU syndrome.

Stunning illustration of how advances in cellular genomics can disentangle links between gene variants & clinical outcomes. Here, saturation editing revealed distinct neurodevelopmental disorders involving the same non-protein-coding gene. 🙌 @nickywhiffin.bsky.social @gregfindlay.bsky.social & co🧬🔬🧪

How do immune disease-relevant variants rewire gene regulation in CD4+ T cells?
In a collaboration led by Daniel Schraivogel and Lars Steinmetz at @embl.org, we combined two large-scale CRISPRi screens (4.1M cells) to map the downstream cascades of thousands of SNPs.

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.

TF-MINDI is out! A new method to learn cis-regulatory codes through rich embeddings of TF binding sites. TF-MINDI decomposes motif neighbourhoods, and works downstream of any sequence-to-function deep learning model. We deeply study the enhancer code in human neural development, check out the thread

Ok here it is - out of 44 FDA approvals this year, 31 are small molecules (70%), 26 of those are oral drugs (84%), 22 of them are chiral (71%). This is the largest number and percentage of chiral FDA approved molecules in a single year. Fitusiran is not a small molecule, bonus.

Review | The inventor of the web says we can recapture its magic. Is he right? In “This Is for Everyone,” Tim Berners-Lee writes about the early days of the internet and how we might restore its more democratic roots.

“The free, open access communications paradigm we have did not arrive like magic. It was the product of a fair amount of political wrangling” - that's why we must continue our fight for the web.
