Clinical Data, Inc. Establishes Scientific Advisory Board for Cardiovascular Genetics.

Company maintains leadership by offering new FAMILION([R]) tests, advancing critical research and collaborating with experts

NEWTON, Mass. -- Clinical Data, Inc. (NASDAQ: CLDA) announced today that its PGxHealth division has established a Scientific Advisory Board (SAB) of leading experts in the field of cardiovascular genetics to advise PGxHealth on its FAMILION cardiac genetic research and clinical genetic testing. The SAB will provide PGxHealth with a multidisciplinary perspective on emerging molecular diagnostics and therapeutics to help advance the standard of care for inherited heart disease patients. The Board members are joining PGxHealth at the American Heart Association (AHA) meeting in Orlando, FL, to discuss additional opportunities for educating and promoting inherited heart disease research to the healthcare community.

"We are excited to formalize the relationships that we have cultivated over the years by bringing together in our Scientific Advisory Board these outstanding clinicians and genetic researchers," said Benjamin Salisbury, Ph.D., Vice President of Clinical Genetics at PGxHealth. "Through our SAB, as well as through our ongoing relationships with other academic and industry collaborators, PGxHealth remains at the forefront of innovative research in this area and will continue to offer the most clinically relevant cardiac genetic tests to healthcare providers."

The SAB members were chosen for their extensive investigations into the causes of inherited heart diseases, including cardiac channelopathies and cardiomyopathies, and their clinical expertise in treating these diseases. The members of PGxHealth's Scientific Advisory Board are:

* Michael Ackerman, M.D., Ph.D., Pediatric Cardiologist at the Mayo Clinic and Director of Mayo's Long QT Syndrome Clinic, as well as Director of the Mayo Clinic Windland Smith Rice Sudden Death Genomics Laboratory;

* Martin Maron, M.D., Director, Hypertrophic Cardiomyopathy Center, Tufts Medical Center;

* Silvia Priori, M.D., Ph.D, Professor of Medicine Director of Cardiovascular Genetics, Langone Medical Center, New York University, Associate Professor of Cardiology, Director of Molecular Cardiology, Fondazione Maugeri University of Pavia, Italy;

* Jeffrey Towbin, M.D., Director of Cardiology and Co-director of Heart Institute at Cincinnati Children's Hospital, and

* Arthur Wilde, M.D., Ph.D., Academic Medical Center, Amsterdam, The Netherlands.

In addition to attracting leading experts to its SAB, PGxHealth's leadership in cardiovascular genetic testing has been underscored by recent events, presentations and publications including:

* Launch of the sixth FAMILION test, the FAMILION DCM Test for Dilated Cardiomyopathy, an inherited disease which is the leading cause of heart transplants and a possible cause of sudden cardiac death.

* Oral presentation at AHA 2009, "Evidence that Rare Missense Variants Seen in Long QT Syndrome-susceptibility Genes in Healthy Volunteers are not Pathogenic," presented in association with Mayo Clinic collaborators.

* Publication in the current issue of the journal Circulation, "Genetic Testing for Long QT Syndrome - Distinguishing Pathogenic Mutations from Benign Variants." Results of a multi-center study of Long QT Syndrome, a potentially lethal and highly treatable disorder involving the heart's electrical system, demonstrate that mutation type and location are critical determinants for distinguishing background noise from true LQTS-causative mutations.

* Publication in the Heart Rhythm journal, "An International Compendium of Mutations in the SCN5A-Encoded Cardiac Sodium Channel in Patients Referred for Brugada Syndrome Genetic Testing." A retrospective analysis of Brugada Syndrome (BrS), a common heritable channelopathy, involving an international consortium of databases from 9 genetic testing centers, adds 200 new BrS-associated mutations to the public domain. http://www.heartrhythmjournal.com/article/S1547-5271(09)01142-4/abstract.

PGxHealth is committed to providing patients with access to the FAMILION family of genetic tests and has successfully contracted with major insurance companies, accepts Medicare assignment and is an approved Medicaid provider in certain states. The FAMILION LQTS Test now has coverage policies and agreements that cover over 250 million patients, representing an increase of over 50 million patients in 2009. In-network coverage by private payers also continues to increase, resulting in lower out-of-pocket costs for patients.
