In our new study, we investigate how GWAS test statistics behave when a trait’s genetic architecture includes epistasis. We first model the bias mathematically and show via simulations how linear models can produce spurious significance (more in comments). www.biorxiv.org/content/10.1...

Bias in genome-wide association test statistics due to omitted interactions

Over the past two decades, genome-wide association studies (GWAS) enabled the discovery of thousands of variants associated with many complex human traits. However, conventional GWAS are still widely ...
