Focused Pharmacogenomics Panel

Test in Focus

Mayo Clinic Laboratories’ updated focused pharmacogenomics panel uses real-time, PCR testing for targeted genotyping of 10 genes with known associations to medications used to treat a variety of disorders across a spectrum of specialities. In this “A Test in Focus” episode of the "Answers From the Lab" podcast, Ann Moyer, M.D., Ph.D., explains how this innovative assay helps guide providers on choosing the best treatment option for their patients.

“The goal of this panel would be that it should be useful for patients that are either on many different medications or patients where the differential diagnosis is still rather broad, where it's difficult to decide which medication to put the patient on,” Dr. Moyer says “Because these drugs metabolize so many different medications, hopefully this is a panel that, once the patient has it ordered, it can be reused again and again, throughout their care, no matter what specialty they're seeing.”

By including both genotype and phenotype evaluation of those genes with a high level of evidence for metabolic associations to medications, the test enables detailed insights on patients’ genetic dispositions, Dr. Moyer says. “We tried to be really careful and cognizant about making sure that we include all of the alleles that are relevant for various patient populations throughout the world. And I think that makes our tests something that should be useful for years to come.”
