Testing for at-risk family members

Genetic testing for family members

Follow up testing for blood relatives

Genetic test results may have health implications not only for an individual, but for an entire family. If you receive a positive test result, family variant testing can help identify other family members at risk for the same genetic disease. Family members who test positive can work with their doctors to make a plan for prevention or early detection of disease.

Invitae offers family variant testing for all blood relatives of patients who undergo gene or panel testing for a hereditary condition at Invitae and are found to have a positive test result.

When to consider family follow-up testing 

I received a positive test result

If you tested positive for a disease-causing (pathogenic or likely pathogenic) variant, your family members have up to a 50% chance of having the same variant.

If they also test positive, they may have an elevated risk of developing disease and can look into options for prevention and early detection. If they test negative, their risk of developing the disease may be similar to the general population.

There are a few steps you can take:

  • Talk to your doctor or one of Invitae’s genetic counselors to determine which of your family members could be at risk. Call Invitae at 800-436-3037, Monday through Friday, 5:00 am to 5:00 pm Pacific.
  • Provide your family members with a copy of your genetic test report. We know that discussing your health can be difficult, so we created template letters to family members to help begin the conversation.
  • Encourage your family members to discuss the option of genetic testing with their doctor.

If your family member has a disease-causing (pathogenic or likely pathogenic) variant, you may have up to a 50% chance of having the same variant.

If you also test positive, you may have an elevated risk of developing disease. With this knowledge, you can consider options for prevention and early detection. If you test negative, your risk of developing the disease may be similar to the general population.

There are a few steps you can take:

  • Obtain a copy of your relative’s positive genetic test report.
