Multi-gene panel tests look for inherited mutations in many genes at the same time. These tests look for genes that are less common and less information may be known about them. The list below includes some of the more common genes linked to breast cancer. Some tests may include additional genes not listed below. A genetics expert can make sure that the right test is ordered based on your personal situation and family history. They will also make sure that your test results are interpreted correctly.
Genes linked to breast cancer in women
Mutations in the following genes have been linked to increased risk for breast cancer in women.

Genes linked to male breast cancer
Mutations in the following genes have been linked to male breast cancer risk.
Some inherited mutations have been linked to certain types of breast cancer.
- People with inherited mutations are more likely to develop than any other subtype of breast cancer.
- People with mutations are more likely to develop lobular carcinoma than ductal carcinoma.

Expert Guidelines
The National Comprehensive Cancer Network has guidelines on who should undergo genetic counseling and testing. If you have been diagnosed with breast cancer, you should speak with a genetics expert about genetic testing if any of the following apply to you:
- You have a blood relative who has tested positive for an
- You have any of the following:
- Breast cancer at age 50 or younger
- Male breast cancer at any age
- Ovarian cancer at any age
- at any age
- Two separate breast cancer diagnoses
- Eastern European Jewish ancestry and breast cancer at any age
- Lobular breast cancer and a family history of diffuse gastric cancer
- For treatment decisions for people with breast cancer or people with early , breast cancer who are at high-risk for recurrence
- Testing of your tumor shows a mutation in a gene that is associated with
OR
- You have one or more close family members who have had:
- Young-onset or rare cancers
- Breast cancer at age 50 or younger
- Male breast cancer, ovarian cancer, pancreatic cancer, or cancer at any age
- Two separate cancer diagnoses
- prostate cancer or cancer that is high-risk or very-high-risk group.
The American Society of Breast Cancer Surgeons (ASBrS) released guidelines in 2019 that recommend all women diagnosed with breast cancer have access to genetic testing for inherited mutations in breast cancer genes.
If you are uncertain whether you meet the guidelines above and you are interested in or considering genetic testing, you should speak with a cancer genetics expert.
Paying For Care
Insurance coverage for genetic counseling and testing
Most health plans cover genetic counseling and testing for inherited gene mutations linked to cancer in people who meet the national guidelines. The cost of testing and your out-of-pocket charges may vary based on several factors.
People who are denied coverage for genetic testing can file an appeal (FORCE has sample appeal letters). Your healthcare provider can work with your insurance company and help you file an appeal if needed. Low cost testing may be available for $250 or less. Learn more about coverage for genetic counseling and testing here.

testing under the Affordable Care Act
Under the Affordable Care Act (ACA), insurance companies must pay for both genetic counseling and testing with no out-of-pocket costs for women who meet certain criteria. The ACA regulations are limited to testing for and only and do not cover genetic counseling or testing in all situations. You can learn more about testing under the ACA here.
Medicare and Medicaid coverage of genetic testing
Genetic counseling and testing is typically covered by Medicare for people already diagnosed with cancer who are in treatment or for whom test results may affect their care. Most state Medicaid programs cover genetic testing for and mutations for people who meet requirements, which vary by state. You can read more about Medicare and Medicaid coverage of genetic testing here.
Financial assistance or low cost genetic testing
JScreen is a national program based out of Emory University that provides low-cost at-home genetic counseling and testing with financial assistance available. Many laboratories offer low-cost genetic testing or financial assistance programs. Programs vary, so if you are not eligible for assistance through one lab, consider contacting other labs to see if you qualify .
