Whole genome sequencing has largely been used as a research tool, but is currently being introduced to clinics.[3][4][5] In the future of personalized medicine, whole genome sequence data will be an important tool to guide therapeutic intervention.[6] The tool of gene sequencing at SNP level is also used to pinpoint functional variants from association studies and improve the knowledge available to researchers interested in evolutionary biology, and hence may lay the foundation for predicting disease susceptibility and drug response.
