Propel testing excellence with Mayo Clinic quality
Mayo Clinic Laboratories is a one-stop laboratory solution, offering commercial laboratories a vast testing menu, unparalleled customer service, and optimized processes. We work collaboratively with partners to assess their needs, providing the testing they need to expand into new areas and meet their business goals.
As the reference lab for Mayo Clinic, we’ve developed robust logistics and testing protocols applied uniformly for all specimens received, no matter their geographic origin. Whether you send us one test order or thousands, each sample receives the same treatment and level of care, ensuring superior results that help our partners better serve their clients.
“Our clients want personal experiences. They want someone to answer the phone. They want someone to provide answers when they're looking for results of a sample sent a couple days ago. and we deliver those answers.”

This week's research roundup feature: Variants of uncertain significance (VUSs) in BRCA2 are a common result of hereditary cancer genetic testing. While more than 4,000 unique VUSs, comprised of missense or intronic variants, have been identified in BRCA2, the few missense variants now classified clinically as pathogenic or likely pathogenic are predominantly located in the region encoding the C-terminal DNA binding domain (DBD). We report on functional evaluation of the influence of 462 BRCA2 missense variants affecting the DBD on DNA repair activity of BRCA2 using a homology-directed DNA double-strand break repair assay.
