Revelatory evaluations to advance awareness and individualize care
For more than 50 years, Mayo Clinic Laboratories has been providing meaningful results to individuals seeking genetic answers. Rare genetic disorders can be among the most difficult conditions to diagnose. To provide meaningful answers, our genetic testing is developed and supported by an integrated team of clinical, genetic, and laboratory experts and uses precision technologies to reveal variations related to diagnosis and treatment. Built around a tradition of placing patients’ needs first, our testing generates personalized insights to elevate understanding of a patient’s condition.
“We understand supplemental assays come with additional cost and effort, but our commitment to providing complete and accurate results for our patients motivates us to go beyond standard lab testing processes.”
Wei Shen, Ph.D., associate director of the Clinical Genome Sequencing Laboratory at Mayo Clinic.

Cherisse Marcou, Ph.D., and Kristen Rasmussen, M.S., CGC, explain how Mayo Clinic Laboratories' WESPR whole exome sequencing reflex test provides cost-effective diagnosis of complex genetic conditions. Using samples and data from previous targeted gene panels, WESPR's wider net can identify undetected genetic variants.
In the last decade or so, genetic testing has evolved from single-gene Sanger based assays to much more complex next-generation sequencing (NGS) based assays. This incredible technology has facilitated the rapid and high-throughput evaluation of many genes (hundreds of thousands of DNA strands) all at once.
This week's featured chromosomal microarray test in focus is presented by William Sukov, M.D., a pathologist and cancer geneticist at Mayo Clinic. He discusses when this test should be used for patients with renal tumors.
Newborn screening panels that test for a variety of conditions are available in every state; however, test performance and response rate by each state are very different. Mayo Clinic's Biochemical Genetics Laboratory created the Collaborative Laboratory Integrated Reports tool to mitigate the national (and international) problem of false positives and to raise the bar on test performance.
Ann Moyer, M.D., Ph.D. gives an overview of this new test available through Mayo Clinic Laboratories. She discusses when this testing should be ordered, how this testing improves upon other testing approaches, and what clinical action can be taken due to the results of this testing.
Ann Moyer, M.D., Ph.D., discusses an additional gene, NUDT15, which is important in the prediction of thiopurine-related toxicity This gene has been added to our TPMT genotyping assay available through Mayo Medical Laboratories.
Devin Oglesbee, Ph.D., Director of the Biochemical and Molecular Genetics Laboratories at Mayo Clinic, provides an overview of the lysosomal storage disease panel, when it is appropriate to order this test, what actions the results allow you to take, and how this test improves upon previous approaches.
Detection of individuals with low thiopurine methyltransferase (TPMT) activity who are at risk for excessive myelosuppression or severe hematopoietic toxicity when taking thiopurine drugs.
