The Genomic Medicine Institute (GMI) serves as the expert base for the principles and practice of genomic medicine, including genetics and genomics research, clinical care, and outreach and education directed at genomics-based personalized healthcare. Research conducted at GMI focuses on both translational and clinical human genetics and genomic science, meaning discoveries made in the laboratory will advance the field of precision medicine and, ultimately, improve the quality of patient care.
GMI, founded over a decade ago by Charis Eng, MD, PhD, Chairperson, is specifically designed with open laboratory space in order to enhance genomics research. Researchers work together with clinicians in the clinical arm of the Institute — the Center for Personalized Genetic Healthcare — as well as the Genomic Medicine Biorepository, which processes and stores thousands of patient samples and biological molecules linked to a relational database, and the Genomics Core facility, which utilizes cutting-edge genomics technology for multiple researchers within the Cleveland Clinic and externally.
The Institute offers a unique training program to young investigators who wish to apply genomics to their research or medical practice. GMI also coordinates genomic research and practice across many disease areas to enhance interdisciplinary research and healthcare.

Pharmacogenomics: An Emerging Clinical Tool
Inter-patient variability in response to medications is an ongoing concern in the medical field. Despite adjustments for age, weight, concomitant medications, and renal or hepatic function, certain patients respond well, some experience severe adverse effects while others do not respond to the same drug therapy. Numerous studies, spanning several decades, have demonstrated that genetic polymorphisms are one of the main factors that influence medication response.
Pharmacogenomics, the study of how an individual’s genetic variations impact the response to drugs, has emerged as an essential tool to optimize therapy and minimize the risk of adverse effects. In general, genetic polymorphisms result in alterations of pharmacokinetic and/or pharmacodynamics properties which are then reflected in therapy outcomes that range from potentially life-threatening adverse effects to inadequate therapeutic response. The goal of pre-emptive pharmacogenomics testing is to take into account the impact of each individual’s genetic variants when selecting therapy thus providing personalized medicine. The benefits of incorporating pharmacogenomics can be exemplified in patients who are diagnosed with major depressive disorder. The majority of patients will need 6 to 12 weeks on a steady antidepressant dose to experience sufficient symptom relief. However, some patients will experience adverse effects or insufficient improvement necessitating changes in therapy and extending the time to remission of symptoms. This results in frustration for the patient along with potential for poor outcomes and higher treatment costs. Pharmacogenomic testing may help identify subsets of the population who carry genetic variants that may alter psychotropic response to specific antidepressants. With this information, clinicians can minimize the need to trial various antidepressants and the time to a positive therapeutic outcome.
Many commercial laboratories offer pharmacogenomics testing but testing is not standardized,
thus results and interpretations may differ between laboratories. This can lead to confusion and can make clinical application of pharmacogenomic results difficult. To address this concern, Molecular Pathology and Pharmacy are collaborating to develop an in-house pharmacogenomics testing process to provide an additional clinical tool to strengthen the ability to provide quality patient care. Until then to assist with testing and interpretation, the Center for Personalized Genetic Healthcare (CPGH), the clinical arm of the Genomic Medicine Institute (GMI), offers a Pharmacogenomic Clinic that welcomes referrals. This clinic is interdisciplinary and currently staffed by our clinical geneticist, Angelika Erwin, MD and our pharmacogenomics clinical specialist, Jennifer Hockings, PharmD, PhD. Although pharmacogenomics has great potential for clinical utility when used accordingly, many third party payers, including Medicare, may only cover testing for certain disease diagnoses and usually after therapy failure. It is important that patients are aware they may have out-of-pocket costs associated with pharmacogenomics testing.
If you have any questions, please contact the pharmacogenomics clinical specialist, Jennifer

Charis Eng, MD, PhD, was awarded a computational grant (110,000 resource units) from Ohio Supercomputer Center, Columbus, for a project titled: “Insight into Structure and Dynamics from Computational Modeling and Simulation: The Effects of Germline PTEN Mutations in Autism Spectrum Disorder and Cancer.” The project is aimed at understanding the dynamics and structure of PTEN in Autism Spectrum Disorder (ASD) vs. cancer-associated mutations in context of the lipid membrane as well as its lipid substrate phosphatidylinositol 3,4,5 triphosphate (PIP3) and adenosine triphosphate (ATP). “Understanding the functional impact that ASD- vs. cancer-associated germline PTEN missense mutations have on the structure of PTEN will aid in a better clinical-molecular classification and prediction of associated phenotypes,” says postdoctoral fellow Iris N Smith, PhD, who is working on the project. “This will potentially allow for translation into new diagnostic and therapeutic approaches.

10/6/17 - Charis Eng, MD, PhD, along with co-senior author Stephen Grobmyer, MD, uncovered differences in the bacterial composition of breast tissue in healthy women compared to that of women with breast cancer. The findings were recently published in the journal Oncotarget. According to Dr. Eng, this study of the breast tissue, oral and urinary microbiomes in breast cancer is the first to examine both breast tissue and distant sites for bacterial differences in breast cancer.
“Our hope,” said Dr. Eng, “is to find a biomarker that would help us diagnose breast cancer quickly and easily. In our wildest dreams, we hope we can use microbiomics right before breast cancer forms, and then prevent cancer with probiotics or antibiotics.”
Breast cancer is the second most common cancer in women (after skin cancer) in the United States, where 1 in 8 women will develop the disease in their lifetimes.

1/19/17 - Since her discovery of the PTEN gene in 1997, cancer geneticist and Cleveland Clinic Genomic Medicine Institute Chair, Charis Eng, MD, PhD has collaborated with physicians and scientists across the nation to determine the impact of a PTEN gene mutation. Their research determined that this gene, in some cases, can cause both cancer and autism. This subtype of autism has been named PTEN-ASD and is estimated to affect up to 2% of individuals with autism.
That was the story of a boy in Tulsa, Oklahoma, Charlie Ryan, one of Dr. Eng’s patients at Cleveland Clinic’s Center for Personalized Genetic Healthcare. After her son developed autism and a benign tumor - Charlie’s mother was determined to find out what could cause such seemingly polar diseases. Her research led Charlie to Cleveland Clinic to be treated by Dr. Eng and autism expert, Thomas Frazier, PhD. In a story by Spectrum, an autism news site, Charlie’s parents tell their story. The article also includes how PTEN was discovered, the impact of a PTEN gene mutation, and finally, the treatment options for Charlie and others like him. Read the whole story on Spectrum’s website here.
