Description

A large number of sequence variants have been linked to complex human traits and diseases, but deciphering their biological function remains a daunting challenge especially for the non-protein-coding variants. To fill this gap, we have systematically assessed the differential binding of transcription factors (TF) to different alleles of non-coding variants in the human genome. Using an ultra-high throughput multiplex protein-DNA binding assay, we examined the binding of 270 human TFs to 95,886 common sequence variants within the 110 type 2 diabetes (T2D) risk loci. We then employed a machine-learning approach to derive computational models to predict differential DNA binding of 124 TFs to other common non-coding variants in the human genome. We showed that the newly derived models outperformed current position-weight matrices (PWM) in describing TF binding to non-coding variants, and facilitated discovery of potential causal variants and dysregulated molecular pathways in human diseases.
