🚨 Big news at #ACMG2025! 🚨
Today we’re announcing global democratization of deidentified allele count + frequency data with population breakdown from the first ~250k short-read WGS in All of Us designed to plug straight into clinical workflows. It is ~1.1 billion unique variants! 🧬💡

🚨 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.👇

Excited to share our @varianteffect.bsky.social CVI workstream preprint! Herein, we discuss important considerations for integration of multiplex functional data to generate a single score set and how this is likely to impact variant classification now and in the future

In our updated TraitGym preprint (w/ @gonzalobenegas.bsky.social & Gökcen Eraslan), we evaluate Evo 2 on regulatory variants associated with human traits. We see marked performance gains with scale on Mendelian traits, although still a bit behind alignment-based methods.

I'm very happy to share our latest work with Seth Berger and the UCI-GREGoR team. Using long-read sequencing, we can detect de novo variants *without* sequencing both parents. We call our method duoNovo.

Interested in rare variants, the X-chromosome, sex-differences, pharmacogenetics, or transcription factors? You might be interested in our new manuscript where we identified >700 functional rare variants with a difference in effect by sex in GTEx! bit.ly/x_rv_sex #genomics #multiomics 💻🧬
Functional impact of rare variants and sex across the X-chromosome and autosomes
The human X-chromosome contains hundreds of genes and has well-established impacts on sex differences and traits. However, the X-chromosome is often excluded from many genetic analyses, limiting broad...

What if one variant can cause splicing outliers transcriptome-wide? In our preprint, we show how examining transcriptome-wide patterns of splicing outliers can both diagnose individuals with rare spliceopathies and uncover novel disease-gene relationships! (www.medrxiv.org/content/10.1...)
Transcriptome-wide outlier approach identifies individuals with minor spliceopathies
RNA-sequencing has improved the diagnostic yield of individuals with rare diseases. Current analyses predominantly focus on identifying outliers in single genes that can be attributed to cis-acting va...

New work! Wherein we (as in, the AVE ODIC working group) looked at clinical variant classification across genetic ancestry groups in gnomAD and AoU and what we found... is exactly what you might expect, after decades of Eurocentric research. But we also show there's a better way forward! 🧬🖥️
