About the Program

The Massachusetts General Hospital’s Preventive Genomics Clinic empowers patients to better understand, predict and prevent disease using genetic information.

We have made tremendous progress in discovering subtle differences encoded in our DNA that can significantly change risk of important diseases—including cardiovascular disease, cancer and diabetes. The next chapter is to translate these discoveries into enhanced care for our patients.

Our clinic brings together a team of genetic counselors, clinical geneticists and physicians to provide individualized testing and treatment plans based on state-of-the-art genome interpretation. We work with our patients and their health care teams to develop a plan aimed at minimizing any risks identified for patients and their families, including helping to decide if genetic testing is right for you and discussing previous genetic testing results.

Common reasons for referral to our clinic include:

  • Consideration of genetic testing based on family history
  • Preventive genomic risk assessment (such as clinical whole genome sequencing or expanded carrier screening) for healthy individuals
  • Follow-up consultation for prior genetic testing (direct-to-consumer genetic test results, genetic research results such as those from the Partners HealthCare Biobank, genetic test results shared by family members)

For Patients

About the Appointment

Note for MA residents and non-MA residents in light of COVID-19: If you are a Massachusetts resident, your Preventive Genomics Clinic visit can be virtual (over Zoom) and we can coordinate genetic testing remotely. The genetic testing lab will send a saliva sample collection kit to your home with instructions and a return shipping label. If you are an out-of-state patient, you will need to come into Boston for an in-person visit. We will provide you with a saliva sample collection tube and will send out your sample to the lab.

How can I make an appointment with the Preventive Genomics Clinic?
If you would like to request an appointment in the Preventive Genomics Clinic, please contact us directly at 617-643-0303 or MGHPreventiveGenomics@mgh.harvard.edu.

What can I expect from my appointment?
You will meet with a genetic counselor and a doctor. We will collect important information about your personal and family history and answer any questions you may have. If you have an interest in genetic testing, we will help you decide which genetic tests will be most helpful for you, and discuss the benefits and limitations of these tests.

What if I already have had genetic testing?
We are happy to discuss previous genetic testing results with patients who have questions about what their results mean or seek a second opinion. Together, we can help you interpret the results, get referrals to necessary medical providers and provide recommendations for your health care maintenance.

About Genetic Testing

What types of genetic testing options are there?
There are many types of genetic tests, from tests that look at a small, targeted list of genes, to those that read all of the letters of your genetic code. We will review the options with you to help you decide which test is right for you.

How is genetic testing done?
Genetic testing is typically performed on a blood sample when possible. In some situations, genetic testing can be performed on other types of samples, such as saliva.

How long will it take for me to get my genetic testing results?
Turnaround time for genetic testing depends on the type of test that is ordered. Some results can be returned within 2-3 weeks, while others may take several months. Your clinicians will review this with you.

Will my genetic testing be covered by my insurance?
Not all insurance plans cover the cost of genetic testing. We will help you navigate insurance coverage and potential costs before genetic testing is ordered.

For Providers

About Our Polygenic Risk Score Test

We offer a polygenic score for coronary artery disease—the disease process that causes heart attacks—in the Preventive Genomics Clinic. Polygenic scores are a new type of genetic test used to estimate your risk for important diseases based on a combination of risk variants across your genome. The test tells you how your genetic risk for heart disease compares to the genetic risk of other people. This is different from most genetic tests that look for the presence or absence of a single genetic variant that has a large impact on your disease risk. A polygenic score assessment may help you and your care team personalize a plan to prevent or understand heart disease. This score was developed by our group at Mass General and the Broad Institute and published in the leading genetics journal, and is calculated by Color Health.

Frequently Asked Questions About the Polygenic Risk Score Test

What does the test tell me?
This test may provide you with information about your genetic risk to develop coronary artery disease. The test will also provide you with information about your risk to develop some cancers and information about how your genetics may effect your body’s response to certain medications.

Do I need to come for an in-person visit to get this test?
If you are a Massachusetts resident, your visit can be virtual and we will coordinate testing remotely. The genetic testing lab will send a sample collection kit to your home with instructions and a shipping label to return your saliva sample.

If you are an out-of-state patient, you will need to come into Boston for a visit. We will provide you with a saliva sample collection tube and will send out your sample to the lab.

What will I have to pay to get this test?
Visits in the Preventive Genomics Clinic are billed as outpatient clinical services to you or your insurance. The polygenic score test costs $249 out of pocket and is not currently covered by insurance. 

Note: We are currently doing a research study to better understand how this test impacts medical care for patients. If you choose to participate in our research study, you will be asked to complete three short surveys and the cost of the polygenic score test will be waived. If you choose not to participate in our study and simply receive our clinical services, the test costs $249 out of pocket. The initial and followup visits are billed like any other clinical visit, and patients should consult their insurance plans for more information on visit coverage.

If you are interested in participating, please email MGHPreventiveGenomics@mgh.harvard.edu with “PRS Cardio Test” in the subject line. If you have any questions about the study, please contact our Genetic Counselor, Deanna Brockman, at deanna.brockman@mgh.harvard.edu or our physician research assistant, Dimitri Maamari, at dmaamari@mgh.harvard.edu.
