NEW ORLEANS, LA--(Marketwire - May 27, 2009) - Kahn Swick & Foti, LLC ("KSF") announces that investors have only until June 30, 2009 to apply for lead plaintiff in a securities fraud class action lawsuit filed in the United States District Court for the Southern District of California, on behalf of purchasers of the common stock of Sequenom, Inc. ("Sequenom" or the "Company") (NASDAQ: SQNM) between June 4, 2008 and April 29, 2009, inclusive (the "Class Period"). No class has yet been certified in this action.

Sequenom and certain of its officers and directors are charged with violating the Securities Exchange Act of 1934 by issuing a series of materially false and misleading statements during the Class Period. On April 29, 2009, the Company revealed significant problems related to its Down syndrome test "SeQureDx," including the mishandling of test data and associated results, which would cause it to be unable to bring SeQureDx to the market timely. As a result of this news, Sequenom's shares fell by over $11, a one day decline of over 75%, on high volume of over 85 million shares.

If you wish to serve as lead plaintiff in this class action lawsuit, you must move the Court no later June 30, 2009. Any member of the putative class may move the Court to serve as lead plaintiff through counsel of their choice, or may choose to do nothing and remain an absent class member.
