How do GWAS and rare variant burden tests rank gene signals?

In new work @nature.com with @hakha.bsky.social, @jkpritch.bsky.social, and our wonderful coauthors we find that the key factors are what we call Specificity, Length, and Luck!

It’s that magical time of the year again! This has been a very good year for fall colors here in Chicago.

We are excited to share GPN-Star, a cost-effective, biologically grounded genomic language modeling framework that achieves state-of-the-art performance across a wide range of variant effect prediction tasks relevant to human genetics.

SINGER, our ARG inference method, is finally published and freely available online:

doi.org/10.1038/s415...

It was a long journey – 16 months from initial submission to acceptance. Is it just me, or has peer review gotten more arduous lately? 4+ rounds of review isn't so unusual these days...

SINGER is a method for creating ancestral recombination graphs to understand the genealogical history of genomes. The method has increased speed, and thus scalability, without sacrificing accuracy.

I wrote about gene-gene interactions (epistasis) and the implications for heritability, trait definitions, natural selection, and therapeutic interventions. Biology is clearly full of causal interactions, so why don't we see them in the data? A 🧵:

Another fun year for the #mwpg, this year at the University of Minnesota! Great to see all the trainees participating with their cool work.

A very lucky morning in the Snoqualmie Falls (before hiking up the mountains)!

Beautiful strawberry moon tonight! That sliver of reflection over Lake Michigan adds even more to the moment’s tranquility.

Jennifer Blanc and @jeremyjberg.bsky.social use theory and simulations to study the process of testing for an association between polygenic scores and axes of ancestry variation when confounding factors are present.

Excited for our publication on how the geographic scale of a sample affects the discovery of rare, deleterious variants to be out this week. With a mix of theory, simulation, and data analysis, we show when samples are narrow vs broad, the number of variants discovered and their frequencies change

Defended my thesis proposal this week and am now a PhD candidate! Incredibly grateful for the support from my mentors, friends, and everyone who came to the talk in person and on zoom. I’m so lucky to be around such amazing people and can’t wait to continue this journey!

After a weekend that truly felt like summer (thunderstorms, sunshine, shorts and t-shirts), I just cannot believe that it’s going to dip below freezing again next week
(So says the weather app, which I wholeheartedly hope is wrong)

I wrote about how population stratification in genetic analyses led to a decade of false findings and almost certainly continues to bias emerging results. But we are starting to have statistical tools to sniff it out. A 🧵:

There’s no better getaway than the Oregon spring, and arguably no better therapy (at least for me!) than a few moist, crystal hours alone in the rain washed forest

My book, An Intuitive Primer on Effective Functional Genomics Study Design, is published! I’d really appreciate it if you could help spread the word, and I’d love to hear your thoughts and feedback. I hope people will find it useful.

Finishing up 2024 with some amazing orchids and orchid mantis, hibiscus flowers (incl one very aptly named Hibiscus schizopetalus - look it up, please), butterflies, and so many other wildlife, all happily living under Malaysia’s lush, verdant tropical canopy!

An absolutely breathtaking sunset in Malaysia (with a double rainbow!) to make Christmas 2024 an incredible memory. Another day of feeling grateful for all the beauty in this world, and for being able to appreciate and understand them as much as we can.

Excited to share a new preprint with @jnovembre.bsky.social ! We use a combination of population genetic theory, simulation, and data analysis to ask: how does study design in genetic studies (including biobanks) impact the discovery of rare, deleterious variants?
