SALT LAKE CITY, Dec. 06, 2018 (GLOBE NEWSWIRE) -- Myriad Genetics, Inc. (NASDAQ: MYGN), a leader in molecular diagnostics and personalized medicine, today announced results from an important study to validate the polygenic component of a forthcoming riskScore™ test for Hispanic women who test negative for a hereditary cancer mutation with the myRisk® Hereditary Cancer test. The results are being presented at the 2018 San Antonio Breast Cancer Symposium (SABCS) in San Antonio, Texas.
'A year ago, we launched riskScore as a significant enhancement to myRisk® to provide women of European ancestry with additional genetic information about their lifetime risk of developing breast cancer,' said Jerry Lanchbury, Ph.D., chief scientific officer, Myriad Genetics. 'This year we are excited to presents results from almost 14,000 women which is the largest polygenic study ever conducted for Hispanic ancestry. It is another step in our commitment to make riskScore accessible to all women, including those most underrepresented in our health care system.'
The key data being presented at SABCS are summarized below. Please visit Myriad at Booth #1001 to learn more about genetic testing for breast cancer. Follow Myriad on Twitter via @myriadgenetics and keep up to date with Symposium news and updates by using the hashtag #SABCS18.
Polygenic Score Poster Presentation
Title: Development and Validation of a Polygenic Score to Predict Breast Cancer Risk in Unaffected Hispanic Women Negative for Mutations on a Multigene Hereditary Cancer Panel.
Presenter: Elisha Hughes, Ph.D.
Date: Friday, Dec. 7, 2018, 5:00 - 6:00 p.m.
This study evaluated 87 single nucleotide polymorphisms (SNPs) as breast cancer risk factors through the validation of a polygenic score in 8,487 women of Hispanic ancestry. The results show that the 87-SNP polygenic score was highly predictive of breast cancer risk in unaffected Hispanic women with a significant family cancer history who tested negative for germline mutations in known breast cancer risk genes (p=7.1x10-19). Estimates of relative risk due to SNPs ranged from 0.2 to 3.6 (Graph 1). The clinical implementation of riskScore for women of Hispanic ancestry may significantly improve the management of high-risk Hispanic women who test negative for mutations in with the myRisk Hereditary Cancer test.
'In this study, we identified a novel SNP-based polygenic score that provides significant breast cancer predictive value in individuals of Hispanic ancestry,' said Lanchbury. 'Our next task is to validate the combination of the polygenic score with the Tyrer-Cuzick model in Hispanic women.'
riskScore is a new clinically validated personalized medicine tool that enhances Myriad's myRisk® Hereditary Cancer test. riskScore helps to further predict a women's lifetime risk of developing breast cancer using clinical risk factors and genetic-markers throughout the genome. The test incorporates data from more than 80 single nucleotide polymorphisms identified through 20 years of genome wide association studies in breast cancer and was validated in our laboratory to predict breast cancer risk. This data is then combined with a best-in-class family and personal history algorithm, the Tyrer-Cuzick model, to provide every patient with individualized breast cancer risk. riskScore is a value-added service to Myriad's myRisk Hereditary Cancer test.
About Myriad myRisk® Hereditary Cancer
The Myriad myRisk Hereditary Cancer test uses an extensive number of sophisticated technologies and proprietary algorithms to evaluate 29 clinically significant genes associated with eight hereditary cancer sites including: breast, colon, ovarian, endometrial, pancreatic, prostate and gastric cancers and melanoma.
