Formal Statistical Replication Analysis in Lung Cancer Genome-Wide Association Studies Dozens of genome-wide association studies (GWAS) have identified thousands of single nucleotide polymor-phisms (SNPs) associated with lung cancer risk. However, it remains challenging to translate the...

Star PhD student @ytchang11.bsky.social will present an empirical Bayes method to formally test the replication composite null hypothesis in GWAS, effectively controlling FDR and maintaining strong power. Big downstream implications to check out in her pre-print: www.medrxiv.org/content/10.1....

Long-read transcriptome assembly reveals vast isoform diversity in the placenta associated with metabolic and endocrine function The placenta plays a critical role in fetal development and mediates maternal metabolic effects on offspring health outcomes. Despite its importance, the placenta remains understudied in large-scale g...

@seantbres.bsky.social will talk about a placental long-read RNA-seq isoform reference + how using it with short reads improves transcript quantification and DTE/U analyses. Cool results in the preprint below. More maternal-fetal health work soon in GxE/POE analyses.

Taylor also was recently nominated internally and submitted an early K99/R00 award to NCI. She did a tremendous amount of work for a really exciting proposal!

Quantification method affects replicability of eQTL analysis, colocalization, and TWAS eQTL mapping and TWAS are widely used to contextualize GWAS, yet the impact of RNA-seq processing choices remains unexplored. We find that RNA-seq quantification method and transcriptomic reference su...

@taylorhead.bsky.social will talk about integrating long-read based transcript assemblies can improve QTL mapping and GWAS integration for breast cancer risk, building off her recent work showing eQTL colocalization and TWAS are HIGHLY sensitive to annotation choice.

Super excited to get this out. This collab started a few years ago and is the first paper from it. Here, with experimental and computational approaches we:

1. establish that cell villages can be just as accurate (one might argue more accurate!) than arrayed-based designs

When testing a computational data analysis method: simulated data are good for checking whether the method is doing what you think it should be doing, real data for checking whether what you think it should be doing is any good.

Isoform-level analyses of 6 cancers uncover extensive genetic risk mechanisms undetected at the gene-level - British Journal of Cancer British Journal of Cancer - Isoform-level analyses of 6 cancers uncover extensive genetic risk mechanisms undetected at the gene-level

Very proud of @ytchang11.bsky.social for her first publication from her doctoral research! She conducted very meticulous genomic analyses that uncovered novel isoform-specific mechanistic hypotheses underlying genetic loci associated with multiple cancers.

Higher eQTL power reveals signals that boost GWAS colocalization Expression quantitative trait locus (eQTL) studies in human cohorts typically detect at least one regulatory signal per gene, and have been proposed as a way to explain mechanisms of genetic liability...

Excited to share this preprint from first author Jon Rosen, a postdoctoral fellow in the @klmohlke.bsky.social lab and my lab. We examine eQTL study sample size and how this affects signal discovery and rates of colocalization with GWAS.
