SALT LAKE CITY, May 15, 2026 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. , (NASDAQ: MYGN), a leader in molecular diagnostic testing and precision medicine, joins forces with Nobody Wants This actress Jackie Tohn to raise awareness about the importance of hereditary cancer testing with the MyRisk ® Hereditary Cancer Test.


Through conversations with her physician and genetic testing, Tohn discovered she carried a BRCA1 gene variant after her father was diagnosed with cancer and tested positive for the same variant. With guidance from her physician, she chose to undergo a prophylactic double mastectomy and future oophorectomy.

“I am very proactive about my health, and yet I had no idea how important hereditary cancer screening was,” said Tohn. “Working with my genetic counselor, I learned I had an 85% chance of developing breast cancer and a 65% chance of developing ovarian cancer. Given how high those numbers are, I believe hereditary cancer testing saved my life.”

The hereditary cancer risk for 11 cancer types, including breast, ovarian, uterine and prostate cancers, can be inherited through either the maternal or paternal side of the family. Important risk factors for hereditary cancer screening are:

  • Multiple of the same type of cancers on the same side of the family
  • Young family history of cancer that is diagnosed at a young age (50 or younger)
  • Rare cancer in your family like ovarian, male breast cancer or pancreatic cancer

"The MyRisk test is about empowerment. When you know your risk, you and your provider may be able to build a personalized plan for early surveillance with increased screenings or other risk-reducing measures that could include medication or surgery," said Brian Donnelly, Chief Commercial Officer, Myriad Genetics. "Jackie's result was not the news anyone wants but having that information allowed her and her clinicians to be proactive about managing her health risks.”

More than one in four women in an OB-GYN setting meet the clinical criteria for hereditary cancer testing. 1 For individuals of Ashkenazi Jewish ancestry, like Tohn, the risk is even greater. 1 in 40 Ashkenazi Jewish individuals (men and women) carry a BRCA1/2 gene mutation. Individuals of Ashkenazi Jewish ancestry are 10x more likely to carry a BRCA1/2 mutation compared to the general population at large. 2

“I’m sharing my story because I am a Jewish woman in my 40s and no one had ever talked to me about BRCA ,” said Tohn. “I hope hearing about my experience encourages everyone to learn more about their family health history, start a conversation with their doctor, and explore a genetic test like the MyRisk Hereditary Cancer Test.”

The MyRisk ® Hereditary Cancer Test with RiskScore ® evaluates 63 carefully selected genes to assess hereditary risk across 11 cancer types, including breast, ovarian, uterine, colorectal, and prostate cancers. For breast cancer risk, the RiskScore assessment combines personal history, family history, and ~150 genetic markers to build both a personalized five-year and remaining lifetime risk of breast cancer and is two times more predictive of breast cancer risk than personal and family history alone. 3

Testing can be completed through a healthcare provider or via virtual care using a blood or saliva sample, with results typically available within 14 days. Myriad’s board-certified genetic counselors are available for a complimentary phone consultation to help understand test results and help guide conversations with a healthcare provider. Clinicians can order and receive results through the Myriad patient portal and several electronic medical record platforms including Epic and OncoEMR.

Myriad was the first laboratory to identify and sequence the BRCA genes and has been a leader in hereditary cancer testing for over 30 years, testing over 3 million patients.
