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

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.

What should I bring with me?
Being prepared will help you get the most out of your visit in the Preventive Genomics Clinic. It may be helpful to bring the following information or documents with you to your appointment:

  • Your family history:
    • Discuss your health history with your family members, and write it down
    • Be sure to ask about any medical conditions in your siblings, parents, aunts, uncles, cousins, grandparents, children and grandchildren
    • If you need guidance on the questions to ask your family members, you can find additional resources here
  • Genetic testing results: If you or a family member has had genetic testing in the past, a copy of the results will be helpful to review during your visit
  • Your medical records: Any relevant medical records from non-Partners institutions will be helpful to bring with you
  • Your insurance card
  • A list of questions you hope to have addressed during your visit

What if I don’t have information about my family history?
There are many reasons why a patient may have a limited family history. We can still provide you with information if you are adopted or have limited knowledge of your family history. 

Will my insurance cover my appointment?
An appointment in the Preventive Genomics Clinic may be covered by your health insurance. However, your specific plan may require that you get a referral for your appointment, and may not cover the cost of an appointment. It is important to check with your insurance company to find out about your specific coverage.

How should I get to my appointment?

  • If you are planning on taking the T or commuter rail, we are close to both the North Station and Haymarket MBTA stations
  • If you plan to drive, there are several parking garages close by including the 101 Merrimac Garage, Haymarket Garage, Stanhope Garage and TD Garden Parking Garage.

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

Referrals
Should I refer my patient to the Preventive Genomics Clinic?
The Preventive Genomics Clinic serves individuals who are interested in their risk of genetic disease but typically do not have symptoms of disease. Reasons for referral to our clinic include:
  • Consideration of testing based on family history
  • Preventive genomic risk assessment (such as clinical whole genome sequencing) 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 Biobank, genetic test results shared by family members)

Some patients, such as children or patients with past or current symptoms of an inherited condition, may be directed to other genetics clinics, as appropriate.
