Advancing patient care, education and research in the evolving and promising field of human genetics

The Division of Human Genetics, in the Department of Internal Medicine, offers outpatient and inpatient consultation services, performs clinical and translational research and participates in community education and outreach. Our physicians and faculty collaborate with colleagues throughout our medical center and around world. And the Master of Genetic Counseling Graduate Program addresses the rapidly growing need for genetics professionals.

Our comprehensive services include a Clinical Cancer Genetics Program with risk assessments and genetic counseling to 800 patients yearly and, as needed, their families. A Cardiovascular Genetic and Genomic Medicine Program, in conjunction with Ohio State’s Division of Cardiovascular Medicine, offers consultation for hereditary forms of heart disease at multiple clinics. And the Medical Genetics and Genomics Program provides risk assessment, genetic counseling and, when appropriate, genetic testing for the many different conditions that can run in families. These can range from bleeding and blot-clotting disorders to diseases of the skin, kidney, lung and eye. The Neuroscience Genetics and Genomics Program focuses on neuromuscular disorders, but also provides consultation for a wide array of neurological conditions.

Also, along with offering with risk assessment tools for healthcare providers, the division’s interactive Family HealthLink allows you to estimate your own risk by reviewing patterns of cancer, heart disease and related conditions in your family.

Whether originating from a single gene, a chromosome or inherited genetic disorders encompass a broad span of conditions. The Division of Human Genetics is a leader in providing the most up-to-date, thorough and advanced information available.

Genetic testing can be provided on a clinical or research basis. Genetic testing is routinely performed on a small sample of blood, saliva or cheek swab.

Ray Hershberger, MD

Director of Division of Human Genetics, Professor of Cardiovascular Medicine

Since my 2012 appointment as director, I have worked toward expanding the medical genetics program at The Ohio State University Wexner Medical Center and the clinical cancer program at the James Cancer Hospital and Solove Research Institute. As a physician-scientist, my focus is not only on laboratory and translational research but also in sharing knowledge with others though publishing, advising students and participating in professional societies. I received my MD from University of Nebraska. View my full bio.


Albert de la Chapelle, MD, PhD

Distinguished University Professor, Department of Molecular Virology, Immunology and Medical Genetics, Department of Internal Medicine

I study the coding pathology of proteins and molecules of newly identified genes as well as how genetic mutations contribute to different kinds of cancer. Translational aspects of my research include exploring new diagnostic and therapeutic procedures. I received my MD and PhD at the University of Helsinki in Finland and have served on editorial boards, sharing various findings in book chapters and academic journals. My specialties are mapping, cloning and characterization of genes for cancer predisposition.

Our Licensed Genetic Counselors

Our leaders


Ana Morales Reyes, MS, LGC

I direct, assist and coordinate cardiovascular genomic research studies, maintaining a project database and disseminating information on familial dilated cardiomyopathy (enlargement of the heart). My focus is on peripartum cardiomyopathy and I work as a genetics counselor in this area. After receiving my BS in biology at the University of Puerto Rico, I obtained my MS in genetic counseling from Brandeis University.


Dawn C. Allain, MS, LGC

My practice includes patients in the Adult Down Syndrome Clinic and the Medical Genetics and Genomics Program. Along with studies of genes involved with cutaneous squamous cell carcinoma (skin cancer), I have researched the effectiveness and impact of genetic counseling and helped spearhead the passage of Ohio’s genetic counselor licensure law. I received my BS from the University of New Hampshire in Durham and my MS in genetic counseling from Northwestern.


Heather Hampel Doll, MS, LGC

I received my BS in molecular genetics from Ohio State in 1993, returning to The Ohio State University Wexner Medical Center in 1995 after graduating from Sarah Lawrence College with an MS in human genetics. Since then, I have been a cancer genetics counselor, working closely with families and individuals. Most of my research is concentrated on Lynch syndrome and includes screening all colorectal and endometrial cancer patients for this condition.


Jennifer Roggenbuck, MS, LGC

I am a licensed genetic counselor and assistant clinical professor in the Division of Human Genetics. My area of research is neurogenetics, which studies the genetic factors contributing to the development of neurological disorders.


Kevin Sweet, MS, LGC

Along with doing research on and providing genetic cancer counseling to patients and families, I work with the Coriell Personalized Medicine Collaborative on exploring the use of genomic information and heart issues. I also direct Family HealthLink, an interactive website allowing patients and families to estimate their genetic risk for cancer and heart disease. My degrees include a BS from the University of Wisconsin and an MS from Sarah Lawrence College.


Leigha Senter Jamieson, MS, LGC

Along with my duties in cancer risk assessment and counseling, I research the PMS2 gene associated with Lynch syndrome. I also investigate and coordinate multiple cancer genetics studies, including those aimed at determining hereditary components of chronic lymphocytic leukemia as well as BRCA (breast cancer) gene mutations. I received my BS in molecular genetics from Ohio State and my MS in genetic counseling from the University of Pittsburgh.


Rachel Pearlman, MS, LGC

Along with providing cancer risk assessment and counseling to patients and families, I also research universal screening for Lynch syndrome. Additionally I serve as project manager for the Ohio Colorectal Cancer Prevention Initiative, a study of 4,000 newly diagnosed individuals and their relatives. In 2010, I received my BS in public health from Indiana University and obtained my MS in genetic counseling from the University of Pittsburgh in 2012.


Rebecca Nagy, MS, LGC

Since 1997, I have been a cancer genetics counselor. My research interests include genetic predisposition to non-medullary thyroid cancer, which includes hunting genes that may play a role in this disease. Additionally I coordinate a repository of data and biological samples for individuals diagnosed with thyroid cancer and other endocrine tumors. I received my BS in biology from the University of Iowa and my MS in genetic counseling from the University of Minnesota.


Robert Pilarski, MS, LGC, MSW, LSW

My focus on clinical cancer genetics and translational research includes coordinating studies with the Columbus Breast Cancer Tissue Bank and also on the genetic development of cancerous and noncancerous conditions. Along with providing consultations to those with a history of cancer, I act as a liaison to the Molecular Pathology Laboratory. I received my BS from Michigan State, a MS from the University of Wisconsin and in 2010, a MSW from Ohio State.
