Disease heterogeneity dissection

Diagnosis for the same disease affects individuals differently. However, we don’t know how best to represent biologically meaningful axes of variation within a disease, beyond the standard case vs. control comparison or proxy measure of severity. We combine human genetics, causal inference, and modern AI to address this challenge.

  • Decomposition of genetic associations across many phenotypes
  • Causal representation learning from pleiotropic associations
  • Assessing the biological bases of disease subtypes

Polygenic risk modeling with latent trait-related genetic components

Polygenic risk score (PRS) has been proposed for disease risk prediction with potential clinical relevance for some traits, but its personalized interpretation is generally …

A cross-population atlas of genetic associations for 220 human phenotypes

Using a set of GWAS summary statistics of diseases characterized from both European (UK Biobank and FinnGen) and East Asian (Biobank Japan) populations, we dissected latent DeGAs …
