Recent advances in high-throughput gene sequencing and other omics biotechnologies have served as a springboard for the field of pharmacogenomics. Pharmacogenomics is now generally accepted as the major determinant of variable drug safety, efficacy, and cost-effectiveness. Therefore, widespread use of pharmacogenomics for patient care has become a critical requirement. There is an unprecedented urgency for aspiring and practicing clinicians to become trained on how to interpret data from pharmacogenomic testing in preparation for the future of healthcare i.e., personalized medicine.
