In Monte Carlo, Monaco, for the Keystone Symposium on B cells! On Wednesday, I will talk about our work on B cell activation.

Has anyone phased the srWGS data on AoU, and if so, have an estimate of the cost? 🧬

Question for you all: when you compute polygenic scores, do you sum up only effect alleles with positive betas, or just ALT alleles weighted by their beta whether they're negative or positive? 🤔

Dear bluesky friends, do you have recommendations for creating a data browser to be released along with a paper to allow users query expression of specific genes, cell type annotation on UMAPs, ATAC-seq peaks. Use shiny app? How to host it? How to make it robust and stable for multiple users?

I started listening to it yesterday in the train from NYC back to Boston. Started by the episodes with Aviv Regev, then George Church, and Todd Golub. It’s really great!

In NYC for the Lupus Research Alliance meeting.

Had a great day at the Broad Institute attending a talk by @bpasaniuc.bsky.social and later meeting with him to design future collaborations. It's a joy to be part of this community!

Estimates of the constraint metric s_het from @jkpritch.bsky.social work (doi.org/10.1038/s415...) for a curated list of lupus susceptibility genes. IKZF1 is the SLE risk gene with the most extreme selection on LOF mutations.

Thanks to Dr. Hai Fang and Cell Genomics for this piece that provides a nice summary and contextualization of our recent work: www.cell.com/cell-genomic...

I’ve selected the latest paper by @kauralasoo.bsky.social group to discuss in our journal club this Friday. I’d love to know which papers you all are discussing in your labs! www.cell.com/hgg-advances...

Brazil, you're setting new all-time-highs for activity on Bluesky! 🥇 Brasil, você está estabelecendo novos recordes de atividade no Bluesky! 🥇

I'm hiring! Currently accepting applications for center coordinator, bioinformatics engineer/scientist, and postdoctoral researcher. Please share with those that might be interested: genomeinformatics.github.io/jobs2024/

Glad to work with this group

I recently did a coloc analysis that surprised me for how it can be impacted by a single variant. I initially got colocalization for a given GWAS locus with 254 eQTL catalogue datasets (PP4>0.75). But, after removing a single variant with p = 10^-80 that violates HWE, I get only 13 colocalizations.

Whaaat

It was a very inspiring talk!

From Wu et al, Genome Bio, 2023: "Currently, SEESAW does not support alignment of haplotypes across individuals of different genotype. [...] It would require further work for the methods presented here to group individuals by their haplotype combinations per gene and perform across-sample inference"

I've just registered to attend this lecture by @mollyprz.bsky.social on May 2nd here in Cambridge, MA. hmsc.harvard.edu/calendar_eve...

Is there a resource of _fine-mapped_ GWAS variants (across many traits)? Ideally with PIPs. Sadly the download link for this causalDB website (www.mulinlab.org/causaldb/ind...) is broken :(

I haven't been able to replicate colocs found with @eQTLCatalogue v5 using the v6 data. The summ stats for the dataset/gene/molecular_traits in question are not even available via API anymore. Culprit may be the new fine-mapping-based filtering of summ stats. It worries me a bit. Anyone else?

Spreading the word: The Nigrovic lab (Boston Children's Hospital) is seeking new postdoctoral fellows in the fields of (1) non-coding genetic variants in human autoimmunity and (2) megakaryocyte-neutrophil emperipolesis using 2-photon microscopy and other methods.

The brilliant work by Joyce Kang (Raychaudhuri lab) on the dynamic genetic control of HLA expression across immune cell states is now published in Nature Genetics. rdcu.be/dsrz2

Are any of you familiar with the QuASAR method for allele-specific expression? doi.org/10.1093/bioi... If my interpretation is correct, it throws away relevant data. See here: github.com/piquelab/QuA... Btw, let me know if you have a favorite method to model ASE accounting for overdispersion 🧬

Sad to miss #ASHG2023 but I will advertise a talk by Nicolaj Hackert and Dany Salinas!

Glad to see this out. It’s always lovely to collaborate with the Nigrovic Lab at Boston Children’s. www.cell.com/cell-genomic...

Interested in doing a PhD with me in Sweden? Experimental+computational genomics skills and/or interests? We have an open position! Great environment at KTH on @SciLifeLab campus, staff benefits, well-funded project, close interactions with our New York team. kth.varbi.com/en/what:job/...

I'm delighted to release the first half of my new textbook in human genetics: web.stanford.edu/group/pritch... "An Owner's Guide to the Human Genome: an introduction to human population genetics, variation and disease"

Fresh work from the lab!👇🏼

I've just registered for the PQG Conference (Diversity in Genetics and Genomics) in Boston this October. I didn't submit an abstract as the topic is a bit far from my current research, but I hope to get inspiration for a grant proposal that I've been working on! www.hsph.harvard.edu/pqg-conferen...
