A fast and scalable framework for large-scale and ultrahigh-dimensional sparse regression with application to the UK Biobank
In this project led by Junyang Qian, we developed BASIL, a novel algorithm to fit large-scale L1 penalized (Lasso) regression model using an iterative procedure, and implemented R …
Fast Lasso method for large-scale and ultrahigh-dimensional Cox model with applications to UK Biobank
We propose extending the BASIL/snpnet algorithm to fit the L1 penalized Cox proportional hazards model using a large-scale dataset from a genotyped cohort.
Sex-specific genetic effects across biomarkers
In this study led by Emily Flynn, we discovered a surprising sex-specificity in the genetics of testosterone.
Rare protein-altering variants in ANGPTL7 lower intraocular pressure and protect against glaucoma
We identified an allelic series of rare protein-altering variants in ANGPTL7 that lower intraocular pressure and protect against glaucoma, highlighting ANGPTL7 as a therapeutic …
Assessing Digital Phenotyping to Enhance Genetic Studies of Human Diseases
Large-scale population-based genotyped biobanks with dense phenotypic information provide opportunities for genetic analysis at scale.
Components of genetic associations across 2,138 phenotypes in the UK Biobank highlight adipocyte biology
We developed DeGAs to decompose shared genetic associations across 2,138 UK Biobank phenotypes and identify their underlying pleiotropic structure.
Significant shared heritability underlies suicide attempt and clinically predicted probability of attempting suicide
Using two independent datasets from genotyped cohorts (UK Biobank and electronic medical record (EMR) in Vanderbilt University Medical Center), we quantified the heritability …
Global Biobank Engine: enabling genotype-phenotype browsing for biobank summary statistics
We present Global Biobank Engine as a platform to visualize genome- and phenome-wide associations and perform statistical inference using those association data.
Medical relevance of protein-truncating variants across 337,205 individuals in the UK Biobank study
Using the UK Biobank population cohort, we investigated the genetic effects of Protein-truncating variants (PTVs) and the clinical impacts.
