Thanks to all involved, especially Sophie who has really driven this project, and the participants and funders of All of Us, UK Biobank, and FinnGen. Happy to hear everyone’s thoughts!

Where accuracy is a bit reduced (e.g. T2D), they’re not explained by ancestry, age, BMI, sex, or smoking status. Instead, phenotype definition matters: hospital data-trained models vs PCP differ, as does requiring two codes.

We built models of 15 diseases (prevalent/classification, and 5-year incident/prediction) in UK Biobank, and applied them to All of Us and FinnGen. For the most part, accuracy is preserved for most models

My favorite part of this (and I think it’s been fixed) is that if you reply to that email, it sends a message on that channel. So when someone leaves an institution, their auto reply replies to every single message… including on the #general channel…

Strange numbers with many to many mappings is no basis for a system of genome coordinates

Well it’s a bit funky. For better or for worse, we did 1% max MAF in UKB (all that was easily accessible) and 0.1% in AoU, which makes things very different esp for the missense/synonymous space. I tend to focus on the pLoF partially for this reason and that the effect directions are consistent

Huge team effort led by @wenhanl.bsky.social with collaborators across the Broad, VUMC, and the All of Us Research Program. This is a first release — looking forward to the next round as All of Us keeps growing and we integrate more biobanks

All of Us markedly boosts non-European representation. Nearly half of the significant signals are found only by meta-analysis. Effects are also consistent: across 140 burden associations marginally significant in ≥2 similarity groups, we saw zero opposite-direction effects

Konrad @konradjk.bsky.social · 13/05/2026
New rare-variant findings include pLoF in TIMD4 → elevated triglycerides, TREM1 → umbilical hernia, and TMEM127 → dermatophytosis. For TIMD4, common variants near the locus were known for lipid traits; the rare-variant evidence adds a direction of effect.

Konrad @konradjk.bsky.social · 13/05/2026
Cross-biobank meta-analysis with UK Biobank (up to 786,871 participants, 222 phenotypes) identified 193 pLoF gene–phenotype associations not significant in either cohort alone, 22 with no prior literature evidence.

Konrad @konradjk.bsky.social · 26/03/2026
To nominate disease genes, we introduce two discovery scores: ΔPEPPER flags genes where biological features predicts clinical impact beyond whats published, and DisPo highlights genes under strong constraint with limited literature. Together they prioritize hundreds of candidate genes for follow-up
101
Konrad @konradjk.bsky.social · 26/03/2026
We train a new model trained on biomedical literature (PEPPER_XGB). Mix LOEUF and PEPPER to make an OMELET, which outperforms either each individual model in identifying disease genes
222
Konrad @konradjk.bsky.social · 26/03/2026
We introduce LOEUF-MIS, combining pLoF and top 1% predicted deleterious missense constraint. This captures not just LoF but also gain-of-function and dominant-negative signals.

gnomAD v4's 5x sample increase benefits both common and rare disease: more common variants observed across ancestries improve diagnostic filtering, while more rare variants strengthen constraint metrics for disease gene detection

The analogy I find myself frequently using here: if everyone smoked (or no one did), the heritability of lung cancer would go up. We think about this a lot in the context of cross-biobank comparisons

gs://ukb-diverse-pops-public/misc/pairwise/pairwise_correlations_regressed.txt.bgz - it’s coded in the way that our pan-UKB phenotypes were so not sure if it’s super easy to use but that’s pairwise r_p for ~14k phenos

Konrad @konradjk.bsky.social · 18/09/2025
Tons of lessons learned around carefully controlling population stratification, using heritability as a QC metric, and probably most importantly, quantifying novelty in a mega-phenotype analysis. Some really cool analyses to find interesting biology e.g. allelic series and ancestry-enriched variants

Heh, it was on our list but somehow never made it into the pre-submission checklist. Will do!

Konrad @konradjk.bsky.social · 20/09/2024
Interesting question. We do have a “gnomAD-new” analysis in there but haven’t broken down by ancestry - i fear a lot is going to be driven by “not yet observed” (which is the same across all ancestries)
010
Konrad @konradjk.bsky.social · 20/09/2024
It gets a bit more complicated though - these scores have a mix of impacts of variant-to-gene, as well as prioritizing which genes, when disrupted, lead to phenotypes. Perhaps a new method that combines both these insights optimally will outperform them all!
100
Konrad @konradjk.bsky.social · 20/09/2024
We found that population-focused methods do best for identifying highly impactful variants (de novo’s in individuals with developmental disorders for instance), while the deep learning methods are better at prioritizing inherited variation in biobanks

Konrad @konradjk.bsky.social · 20/09/2024
We have a new preprint that we’d love feedback on! We benchmarked a bunch of variant scoring methods to figure out what they were actually doing, and how they performed across selection regimes: www.biorxiv.org/content/10.1...

As genomic analyses scale to millions of exomes/genomes, we need a scalable infrastructure to process/QC/handle these data while retaining all the metrics needed for downstream analysis. A new preprint from the Hail team proposes a way to do this! Comments welcome: www.biorxiv.org/content/10.1...

Paella is good. With LOEUF I assumed the culmination would be an omelette but CHARR is better in a paella, so maybe it’s a multi-course meal

Extended data figure 2b has exclusive exon-only. I think we internally made some with intermediate overlaps and it was an intermediate result as you’d expect

Interestingly, these scores also provide additional insight into genes regulated by these regions, even those underpowered by previous constraint metrics:

Konrad @konradjk.bsky.social · 06/12/2023
We built a new metric we called gnocchi (genomic non-coding constraint of haploinsufficient variation), building on methods that find depletions of variation (natural selection), which we show can prioritize functional variation
