MIAMI – OPKO Health, Inc., through its subsidiary GeneDx, today announced results from the largest published study to date of patients who received hereditary genetic testing with Next Generation Sequencing (NGS) cancer panels. The study, “Pathogenic and Likely Pathogenic Variant Prevalence among the First 10,000 Patients Referred for Next Generation Cancer Panel Testing,” was published in the December 2015 issue of Genetics in Medicine. GeneDx’s analysis of the data generated from the first 10,030 patients highlights the clinical utility of testing for multiple cancer genes to identify variants that would not have been identified through previously used testing methods. The patients, who were referred for testing between August, 2013 and October, 2014, underwent genetic testing for panels of genes associated with hereditary cancer.
While many patients were found to carry pathogenic or likely pathogenic variants in well-established, high-risk cancer genes, approximately half of the pathogenic variants identified were in genes with moderate risk and in recently identified cancer genes. Notably, among women with breast cancer, 50% of positive findings were in genes other than BRCA1 or BRCA2. Additionally, several individuals had pathogenic variants in high-risk genes that were somewhat unexpected, so clinical presentation alone might not have prompted testing for these genes
“We believe that molecular diagnostic testing for panels containing multiple genes are significantly more accurate in determine the heritable factors which increase the risk of cancer, and may permit more tailored treatment for cancer patients and screening for their family members,” said Sherri Bale, PhD, FACMG, Co-Founder and Managing Director of GeneDx. “Our experience, based on a large database of patients, demonstrates that multi-gene panels have the potential to identify pathogenic variants in genes that would not typically have been tested and most likely would have been missed. This study provides important empirical data for clinical decision-making when choosing between single genes and NGS cancer panel testing for a variety of cancers.”
