Genomics-driven drug discovery based on disease-susceptibility genes.

Genome-wide association studies have identified numerous disease-susceptibility genes. As knowledge of gene-disease associations accumulates, it is becoming increasingly important to translate this knowledge into clinical practice. This challenge involves finding effective drug targets and estimating their potential side effects, which often results in failure of promising clinical trials. Here, we review recent advances and future perspectives in genetics-led drug discovery, with a focus on drug repurposing, Mendelian randomization, and the use of multifaceted omics data.
