Translational Omics Program
Genomically powered medicine
An estimated 25 million Americans are living with rare diseases, most of which are genetic and remain undiagnosed. Genomically powered, individualized medicine is transforming how healthcare teams identify, understand and treat these conditions — while also creating new opportunities to prevent disease before it develops.
Advances in state‑of‑the‑art clinical testing are generating unprecedented volumes of genomic data. For many patients, these data provide long‑sought answers to complex diagnostic dilemmas and, in some cases, open the door to novel therapeutic options. At the population level, large‑scale sequencing efforts demonstrate that genomic findings are broadly applicable and highly impactful in clinical decision‑making, enabling more predictive, preventive and precise care. Together, these advances are reshaping patient care and improving lives.
Translational Omics Program
As genomics becomes a standard component of individualized medical care, the challenge has shifted from data generation to data interpretation. The Center for Individualized Medicine established the Translational Omics Program in 2015 to address this critical need by providing deep postanalytical interpretation for omics‑based clinical and translational research.
The program focuses on rare and undiagnosed genetic diseases, populational genomics, and preventive genomic screening. It brings together a multidisciplinary team that integrates computational analysis, data integration and biological interpretation with traditional in vitro and in vivo functional studies, ensuring that complex omics findings can be translated into clinically meaningful insights.
Training the workforce of the future
The Translational Omics Program's core mission is to develop the next generation of translational genomics experts. It offers a rich, collaborative training environment for postdoctoral fellows, graduate students and interns, equipping trainees with skills that span genomics, bioinformatics and clinical medicine. Through this integrated approach, the program is helping build a workforce prepared to translate omics discoveries into patient care.

Projects
Exome sequencing and genome sequencing have provided diagnostic answers for thousands of patients with rare and undiagnosed diseases and are now widely adopted at institutions around the world, including Mayo Clinic. Despite their impact, current approaches yield diagnoses for only about 30% to 40% of patients, leaving the majority without definitive genetic explanations.
The Translational Omics Program focuses on reevaluating clinically generated sequencing data beyond standard clinical reports. By identifying additional candidate variants and performing targeted follow‑up studies, researchers seek to establish pathogenicity and uncover previously unrecognized genetic causes of disease.
For patients with rare and undiagnosed diseases, the Translational Omics Program employs an integrated, end‑to‑end strategy to maximize diagnostic resolution and enable individualized care.
This work includes systematic reanalysis of existing clinical genomic data as scientific knowledge evolves. Researchers apply complementary genomic, transcriptomic and epigenomic technologies to uncover regulatory and expression‑based disease mechanisms. Then, program members develop scalable, automated approaches for variant interpretation across both individual patients and large populations. They use advanced bioinformatics, structured phenotyping and machine learning methods to connect genetic variation with patient‑specific clinical features, while expanding testing modalities to extend analysis beyond coding regions alone. Finally, the research team further evaluates possible findings through in silico modeling and functional laboratory studies, providing biological validation and mechanistic insight.
Together, these activities transform previously inconclusive results into actionable diagnoses, inform therapeutic strategies, and continuously improve the care of patients with complex genetic diseases.
The RADiaNT project aims to transform care for patients with rare and undiagnosed genetic diseases by integrating complementary RNA sequencing into clinical evaluation. In an initial phase, a subset of successfully diagnosed patients receive personalized antisense oligonucleotide (ASO) therapeutics for evaluation in pilot studies. This work assesses the feasibility of individualized RNA‑based therapies and expands treatment options for patients with rare genetic diseases.
While DNA and RNA sequencing have advanced the diagnosis of Mendelian disorders, some complex cases require deeper insight into epigenetic regulation. Errors in DNA methylation can alter gene expression and contribute to hereditary disease.
To address this gap, researchers are performing methylation sequencing in patients with rare and undiagnosed genetic conditions and integrating these data with existing DNA and RNA results. This comprehensive multi‑omic approach enables more complete molecular characterization and improved diagnostic precision.
Although exome sequencing and genome sequencing have transformed genetic diagnostics, most patients with rare diseases remain undiagnosed or receive results classified as variants of uncertain significance. Meanwhile, new gene‑disease associations are continuously reported in the scientific literature and curated in public databases. The RENEW project uses automated bioinformatics pipelines to identify emerging evidence from major genomic databases and reannotate previously negative or inconclusive exome results. This scalable approach enables rapid reanalysis, allowing unresolved cases to be revisited efficiently as knowledge evolves.
The Translational Omics Program is developing robust annotation frameworks and bioinformatics tools to support large scale population screening initiatives. By leveraging current scientific literature and scalable software solutions, the program enables accurate and efficient interpretation of genetic variation across large cohorts.
Modern genetic testing generates tens of thousands of variants per patient, requiring sophisticated analytics to connect genotype with phenotype. The Translational Omics Program employs intuitive systems to capture clinicians' observations as structured phenotype data, enabling automated analysis and integration with genomic results. The systems cross‑reference these data with scientific literature and biological databases. The research team applies machine learning approaches to prioritize variants most likely to explain a patient's condition.
Beyond short-read DNA sequencing, data from long-read sequencing, RNA, metabolomics and proteomics provide insight into gene structure, activity and regulation. The Translational Omics Program evaluates multi-omic data alongside DNA sequencing to improve diagnostic yield. In a subset of patients, this integrated approach substantially enhances the ability to identify underlying genetic causes of disease.
A major limitation of genetic testing is the prevalence of variants of uncertain significance. To address this challenge, the Translational Omics Program conducts functional studies using protein modeling and experimental systems to evaluate the biological impact of variants. Researchers use genome engineering technologies to introduce patient specific variants into laboratory or animal models, enabling direct assessment of function and supporting more confident clinical interpretation.

Molecular Genetics and Genomic Medicine: Margot A. Cousin, Ph.D.
Dr. Cousin discusses her paper, "Pharmacogenomic Findings From Clinical Whole-Exome Sequencing of Diagnostic Odyssey Patients," which was published in Molecular Genetics and Genomic Medicine."
To determine the impact of the secondary pharmacogenomic findings for these patients, we decided to, you know, start this study, which was recently published in Molecular Genetics and Genomic Medicine, and really discusses the pharmacogenetic findings that we found using whole-exome sequencing on diagnostic odyssey patients.
Whole-exome sequencing is a test that looks at all of the genes in your genome. So some of the benefits include, really, not having to know which gene in particular you want to look at.
So we were in the early stages of starting to use exome sequencing for the care of these patients. What we started to realize is that there's other information contained within that no one would really know about unless you're digging through it. Because you get a lot of results back when you get an exome result, right? And within those results, we're starting to find pharmacogenomic variants listed, and of course that wasn't really necessarily related to the disease that we were searching for an answer for, but its an important result that can be used for patients' care.
In looking at our cohort of patients, of the 94 patients we evaluated for pharmacogenomic findings, the majority were young, median age of ten years at testing. The majority also had a neurologic component to their clinical presentation. Seizures was one of the most common phenotypes described in their reason for referral. In the majority of patients had at least on pharmacogenomic variant reported on their clinical WES test, and one fifth of patients were taking a medication at that time that could be impacted by that result.
I think if you look at our patient population, most of the patients were, I think, the average age was about ten years of age. Usually, we don't worry too much about medications when it comes to this population because they are usually not taking a large number of medications. We're usually concerned about a large number of medications in an older population. However, through this study, I came to realize as a pharmacist that pharmacogenomics matters in almost all age groups. Why? Because some of our patients were taking antidepressants. Some of them were taking anti-seizure medications. Some of them were taking pain medications. Some of them were taking muscle relaxants. All these medications, or some of the medications, are metabolized by some the genes that we identified in our cohort. Meaning that pharmacogenomics could, at a certain point, help these patients who are currently taking medications in our population either make changes either with the dose or change the medication to a different medication.
