At Invitae, we make genetic information more accessible to patients and healthcare providers by offering high-quality, affordable genetic testing.
We believe in the importance of understanding what your genetic information means for you and for your family members. That’s why we offer expert genetic counseling to patients.
This online learning tool is intended to provide information about DNA and genetics, as well as genetic testing and genetic counseling services. It will also focus on the genetics of hereditary breast cancer and the role that family history and genetics play in your health.
This tool can be especially helpful for individuals who have a genetic counseling appointment scheduled with Invitae. To make the most of that personalized conversation, please take a few minutes before your genetic counseling appointment to read through this online learning tool.
If you don’t have time to completely review this tool, you can get started now and come back to it later.

Our topic for today is genetic testing. Let’s start with a short video clip (about 2 minutes) that explains some of the terminology—including genes, DNA, and chromosomes—that will help you understand genetic testing.
Now that you have some familiarity with genes and DNA, let’s talk a little more specifically about genetic testing for breast cancer.
This video clip explains more about some of the features that can be seen in families with hereditary breast and ovarian cancer syndrome (HBOC).
As we have discussed, BRCA1 and BRCA2 are the most common genes known to increase the risk of breast cancer. But there are other genes that can also increase an individual’s risk of developing breast cancer—and other forms of cancer as well.
In addition to testing for BRCA1 and BRCA2, Invitae offers tests for other genes, including:
Invitae’s genetic testing services allow your healthcare provider to select the right genetic test for you. In some cases, that will include only BRCA1 and BRCA2. In other cases, it may include include a broader range of genes in addition to BRCA1 and BRCA2. The test that is selected may depend upon your personal medical history and family health history.
For more information on selecting a genetic test, cost, and insurance coverage, visit Invitae’s patient website.
At Invitae, we believe that capturing a complete and accurate family history is critical to selecting the correct test and interpreting genetic results. Please take a few moments to watch this short clip, which offers some tips for gathering information for your own family medical history.
The Invitae Family History Tool makes it easy to map your family medical history. After you fill out a quick questionnaire, the Family History Tool will automatically generate a diagram of your family history (also called a pedigree).
As you’ve learned, a pedigree is an important tool used by genetic counselors to better understand your cancer risks. If you are scheduled for a genetic counseling appointment with Invitae, you should have received an email with a link to a questionnaire about your family medical history. After you answer the questions, a pedigree will be automatically generated and sent to your Invitae genetic counselor.
Even if you don’t have a genetic counseling appointment scheduled, you can still use our free Family History Tool.
At Invitae, we believe that your genetic information should be personalized—to you. That’s why we offer genetic counseling services to patients who are tested through our lab for cancer risk.
Genetic counseling sessions at Invitae are performed by telephone or video. Sessions typically take 30 to 40 minutes, during which time your genetic counselor will review:
If your genetic counseling session has already been scheduled, you should have received an email confirmation regarding the date and time of your appointment. If you haven’t received this information, please contact us.

Our understanding of cancer genetics is evolving rapidly, with new information being discovered very quickly. Some breast cancer genes—including BRCA1, BRCA2, TP53, and PTEN—have well-known cancer risks, with specific medical management recommendations detailed by the National Comprehensive Cancer Network. Other cancer predisposition genes may have less-established risks, and may lack published recommendations for cancer surveillance. In such situations, your healthcare provider may need to recommend cancer prevention and surveillance measures based on your personal medical history and family health history.
If you have an elevated risk of developing cancer based on your genetic test result, it is important that you work with your doctor to create a medical management plan focused on cancer prevention or early detection. The specific cancer surveillance and prevention measures that your doctor recommends will depend upon your personal medical history, family health history, and specific genetic test results.
Genetic testing can help you and your healthcare provider develop an appropriate medical management plan that is focused on cancer prevention or early detection. Genetic testing can also help clarify the cancer risks for other members of your family.
Knowing about an increased cancer risk can help you and your clinician address it. You might consider:
