Mount Sinai Genetic Testing Laboratory Partners with Counsyl to Expand Screening for Genetic Diseases

Genetic screening tests for more than 100 disorders are available with on-site counseling.

New York, NY
 – January 8, 2013 /Press Release/  –– 

The Mount Sinai Genetic Testing Laboratory (MGTL) has announced a partnership with Counsyl to expand options for prospective parents, for preconception and prenatal genetic screening for a greater number of recessive diseases.

New tests developed by Counsyl, a genomic technology company founded by Stanford University graduates, include carrier screening for conditions such as Smith-Lemli-Opitz, Carnitine Palmitoyltransferase II Deficiency, GJB2-Related DFNB 1 nonsyndromic hearing loss and deafness, and certain forms of limb-girdle muscular dystrophy. Ramji Srinivasan, CEO of Counsyl, said, "As a New York native, I find it personally gratifying to be working with Mount Sinai to make carrier testing available to anyone planning to have children. Mount Sinai has built an incredible reputation in genetic screening, and we're thrilled to partner with them."

Lisa J. Edelmann, PhD, Director, Mount Sinai Genetic Testing Laboratory, said: "This new partnership between Mount Sinai and Counsyl will facilitate access to carrier screening for many more recessive genetic diseases and some of the more common X-linked diseases, so that couples can learn about potential risks at the pre-pregnancy stage to inform reproductive decision-making. Mount Sinai offers prenatal diagnostic testing in combination with on-site expert genetic counseling, thus providing a comprehensive and convenient service for patients and providers." Mount Sinai also provides additional prenatal testing on site, such as rapid 24-hour aneuploidy fluorescent in situ hybridization (FISH) testing, chromosome analysis, and array- comparative genomic hybridization.

Mount Sinai's genetic testing laboratory, part of the Icahn School of Medicine at Mount Sinai, already offers a comprehensive set of screening options for more than 100 disorders, including a cystic fibrosis mutation panel, spinal muscular atrophy test, Tay-Sachs enzyme analysis, and an expanded Ashkenazi Jewish panel. The lab has been a leader in carrier screening for Ashkenazi Jewish genetic disorders and was the first to offer carrier screening for Walker-Warburg Syndrome in this population.

Lawrence Grunfeld, MD, Clinical Associate Professor of Obstetrics, Gynecology and Reproductive Science at the Icahn School of Medicine at Mount Sinai and Co-Director of Reproductive Medicine Associates of New York, recently began providing the expanded genetic screening tests from Mount Sinai and Counsyl to his patients. Dr. Grunfeld commented, "Our expanding understanding of genetics has made the old-fashioned genetic testing obsolete. We can now detect and prevent more and more diseases. Our relationship with Mount Sinai and Counsyl offers our patients state-of-the-art detection of inherited genetic diseases to allow for more informed reproductive decisions."
