Largest Published Study to Date Supports Testing Changes and

Development of New Treatment Options

MIAMI--(BUSINESS WIRE)--

OPKO Health, Inc. (NYSE: OPK) 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.”
