Myriad Genetics Underscores Commitment to Cancer Care Continuum with New Data Presentations at SGO Annual Meeting

SALT LAKE CITY, April 09, 2026 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ: MYGN), a leader in molecular diagnostic testing and precision medicine, today announces that it will share new data at the Society of Gynecologic Oncology (SGO) Annual Meeting, including two oral presentations and two posters.

“Having four abstracts accepted at the prestigious SGO annual meeting underscores the importance of the data we are sharing and our commitment to the cancer care continuum,” said Dale Muzzey, PhD, Chief Scientific Officer, Myriad Genetics. “We are particularly pleased to be presenting the latest Precise MRD™ data, showing that Precise MRD testing after adjuvant therapy for ovarian cancer was significantly prognostic of recurrence during the monitoring period. Importantly, recurrence risk tracked with the quantitative ctDNA fraction detected by Precise MRD, with elevated risk observed even at ctDNA levels detectable only by an ultrasensitive assay.”

The remaining three presentations use data from the Myriad Collaborative Research Registry™ (MCRR), one of the largest pan-cancer registries accessible for research use, including de-identified data for more than 1.3 million participants. The studies demonstrate Myriad’s commitment to externally driven research that addresses diverse questions with immediate clinical implications:

  • Germline pathogenic and likely pathogenic variant prevalence is associated with age and ancestry in patients diagnosed with ovarian cancer before age 40;
  • Ovarian cancer diagnosis varies by Lynch syndrome gene, informing counseling and risk-reducing surgery recommendations;
  • Universal hereditary cancer screening identifies more individuals at high risk for endometrial cancer compared to age-based screening.

These studies will be presented at the Society of Gynecologic Oncology Annual Meeting on April 10-13 at the Puerto Rico Convention Center in San Juan. Myriad will exhibit at booth #523. For more information, visit: https://myriad.com/oncology/oncology-conferences/
