An integrated, scaled approach to resolve TSC2 variants of uncertain significance https://www.biorxiv.org/content/10.64898/2026.01.16.699909v1
Excited to share our work to resolve TSC2 variants of uncertain significance. Will write a proper tweetorial soon! Huge thanks to our many collaborators. This study benefited from the hard work of many folks and I appreciate them lending their time and expertise.

Watching the systematic dismantling of the world's largest funder of biomedical research is heartbreaking and infuriating
NEW: Another NIH institute director hasn't been renewed — the director of NIAMS (arthritis, musculoskeletal and skin diseases institute).
That leaves a whopping 15 of 27 institutes and centers without a permanent director.

🚨 Most variant screens measure growth or abundance. What do they miss? That variants impact a spectrum of protein and cellular phenotypes. Variant in situ sequencing (VIS-seq) finds what’s missing: image cells 🔬 first, decode later, revealing multi-scale phenotypes for thousands of variants.👇

How bad will it be? Catastrophic.
Proposed cuts to #NSF, #NIH, and #NASA will set the US R&D landscape back 25 yrs+, cause economic and job loss now, and undermine innovations to come.
But, this is the WH's *proposed* budget.
Speak up now before it is too late.
