Transforming test results into actionable insights

Since 1992, cases of colorectal cancer have been on a slow decline, yet 52,550 people died from it in 2023. At Mayo Clinic, a cutting-edge menu of both germline (inherited genetic alterations) and somatic (tumors due to non-inherited genetic alterations) testing are two critical tools helping to improve targeted treatments for colorectal and other common gastrointestinal cancers.

Dr. Linda Hasadsri’s firsthand encounter with the genetic tests she’s helped develop has provided rare insight into testing quality and implications, enhancing their ability to advocate for the value of testing and infusing their work with deep empathy.

Recognizing the powerful role genes can play in diagnosing illness and guiding treatment, the Division of Laboratory Genetics and Genomics at Mayo Clinic spearheaded a testing expansion, implementing and upgrading more than 60 advanced sequencing and biochemical assays in 2023 and planning for even more this year.

Prevented from providing testing services to its community members due to a non-compete agreement with a national laboratory, Kootenai Health laboratory leaders deepened their relationship with Mayo Clinic Laboratories, receiving tactical support and guidance to launch an in-house reference lab just days after the non-compete agreement expired.

Multiple doctors and multiple examinations could not figure out why Lauri Sieben had spent much of her life “never feeling quite right” physically. Fortunately for Lauri, that changed after her daughter Christy began working as a genetic counselor in Mayo Clinic’s Molecular Technologies Laboratory. After seeing similarities between the patient testing she was performing for the lab and the physical symptoms being experienced by her mom, Christy took a leading role in getting Lauri to undergo molecular and biochemical testing at Mayo Clinic. The results of that testing not only provided much-needed answers, but a promising path forward for Lauri.

On the brink of losing her battle with acute myeloid leukemia, Shannon Camlek arrived at Mayo Clinic as a last hope. Her chances didn’t look good, but with the help of specialized genetic testing, particularly FISH (fluorescence in situ hybridization) studies, doctors were able to detect the specific gene mutations responsible for her symptoms and disease. The test results also helped Shannon’s care team target her treatment accordingly, and finally put an end to what Shannon likens as starring in her own personal horror movie while in search of hope and healing.

Endometrial cancer affects thousands annually and ranks as the fourth most common cancer among women in the United States. At the forefront of innovative discoveries in endometrial cancer diagnostics are Mayo Clinic's Department of Laboratory Medicine and Pathology consultants. Sounak Gupta, M.B.B.S., Ph.D., vice chair of Oncology Practice for the Division of Laboratory Genetics and Genomics; Maryam Shahi, M.D., senior consultant for Anatomic Pathology; and Andrea Mariani, M.D., M.S., division chair of Gynecologic Surgery, explore the critical significance of molecular profiling and collaborative efforts driving these innovations, highlighting Mayo Clinic’s revolutionary influence on patient care.

One summer morning, James Kypuros awoke to find his toes stiffened like claws. Then he started having falls, which culminated in losing his ability to walk or even sit up without help. Diagnosed with stiff-person syndrome, James wouldn’t find hope or relief until he was treated for glycine receptor antibody syndrome following specialized testing by Mayo Clinic.

For over two decades, Mayo Clinic has been at the forefront of cardiovascular (CV) genetic testing. The current test menu features 24 different panels that span over 300 genes linked to inherited cardiovascular disorders, many of which are rare and challenging to diagnose. Whereas many labs operate in a “silo” — meaning they take a genetic specimen, test it, and then return a result with limited input — Mayo Clinic takes a much more expansive approach.

After immigrating to the United State and becoming a U.S. citizen at the age of 18, Holocaust survivor Kurt Glover-Ettrich chose to give back to his new homeland by serving a 30-year career in the U.S. military. Today, as a Mayo Clinic volunteer, Kurt is giving back in new ways for the 22 years of regular care, treatment, and laboratory testing he’s received in response to the prostate cancer diagnosis that first brought him to Mayo Clinic.

In a recent discovery by Mayo Clinic Laboratories, a novel hemoglobinopathy category was identified and termed epsilon gamma thalassemia. The first instance of the disorder was found in 2017 when an obstetric patient underwent a routine screening for blood-related illnesses such as sickle cell disease and thalassemia. Upon completion of additional tests, doctors found an abnormality they had never seen before.

In August of 2021, 28-year-old Mike Knudson, a Twin Cities resident known for his vibrant and active lifestyle, set out on what he anticipated to be an adventurous hiking vacation to the picturesque Glacier National Park in Montana. Little did he know that this journey in nature would be the start of an unexpected life path.
