🧵 Our latest preprint is available. It describes an extraordinary case of a boy with two very rare genetic conditions: Fanconi anaemia (FANCB, with a deep intronic pathogenic variant) and embryonic triploid–diploid mosaicism. Read more here 👉 medrxiv.org/content/10.1101/…

Earlier this year, I learned I have a pathogenic variant in BRCA2, which gives me a very high lifetime risk of breast cancer (55-69%), as well as an increased risk of ovarian cancer (12-29%) and pancreatic cancer (5-10%).

Today in @CellCellPress we report the use of prime editing to correct several mutations that cause alternating hemiplegia of childhood (AHC), a rare and devastating neurodevelopmental disorder, in patient-derived cells and in two mouse models.

In my several decades in science, few moments have been as seismic as when AlphaFold burst onto the scene (seeing the first structure of a K+ ion channel, from Rod MacKinnon, was up there too). We rushed to fold every protein we had been working on, that had no structure, and suddenly so many things made sense. AF, then AF2 and AF3, are daily workhorses in our business of protein engineering.
And I am beyond thrilled that my friend and collaborator David Baker has also received the prize. One of the projects I’m most proud of was a computational design collaboration with him to produce a resorufin fluorophore ligase, and it was miraculous when the crystal structure matched his computational design exactly (pnas.org/doi/10.1073/pnas.14…). We use the tools David’s lab has produced, such as proteinMPNN and RFDiffusion, daily. As incredible as David’s contributions have been, I feel that his best work is ahead of him.

Our lab's latest is now out on BioRxiv. In this work we set out to understand how 'shieldin' regulates #DNArepair, focusing on its physiological function in B cells & pathological contributions to BRCA1-mutant cancers. Some background & take-home msgs (1/) biorxiv.org/content/10.1101/…

Very interesting paper from the @KarleneCimprich lab and collaborators, showing that HLTF removes G4 structures, using a very different mechanism from other proteins characterized to date. Thanks for having us on board!

Having a hard time with #CRISPR HDR? Your cells might be fighting against you! TREX1 nuclease, high in some cells, eats up HDR donor templates.
