LOS ANGELES, June 12, 2014 (GLOBE NEWSWIRE) -- Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests that help guide cancer therapy selection, today announced that the National Institutes of Health (NIH) Genetic Testing Registry (GTR), a searchable database of genetic and genomic tests, has been updated to include the recently introduced ResponseDX: Tissue of OriginTM test. Response Genetics acquired this test as part of its acquisition of the assets of the former PathWork Diagnostics in late 2013 and introduced the test, the only FDA-cleared test of its kind, to the market in February 2014. The GTR offers detailed clinical and scientific information about testing options for physicians and patients.

"We are very proud that the GTR has elected to include the ResponseDX: Tissue of OriginTM test, and will soon include all of our other molecular tests in the Response Genetics portfolio", said Thomas A. Bologna, Chairman and Chief Executive Officer of Response Genetics. "A centralized information repository searchable by laboratory, mutation, test, etc. is a tremendous benefit to the community of oncologists, pathologists and patients we serve. In addition to including the basic information about the ResponseDX: Tissue of OriginTM test, namely that is an FDA-cleared, Medicare-reimbursed gene expression analysis that provides a definitive diagnosis for poorly-differentiated or metastatic cancers without a clear primary origin, the GTR also includes detailed information about the test's development, validation and clinical utility making this information easily accessible to physicians, researchers and patients.

"We are very pleased to add Response Genetics' ResponseDX: Tissue of OriginTM test to the GTR, particularly since it is the first test in GTR that is used to identify the tissue in which a malignancy originates," said Wendy Rubinstein, M.D., Ph.D., Director of the Genetic Testing Registry and Senior Scientist at the National Center for Biotechnology Information, a division of the National Library of Medicine at the National Institutes of Health. "Our goal is to provide an efficient means for health care providers, researchers, and others to access detailed information about the broad range of available genetic and genomic tests. The addition of the Response Genetics menu of genomic tests for cancer to our database will significantly further this goal."
