Abraham, Fruchter & Twersky, LLP Files Class Action Lawsuit Against Sequenom, Inc.

NEW YORK, NY--(Marketwire - May 7, 2009) - Abraham, Fruchter & Twersky, LLP filed a class action lawsuit in the United States District Court for the Southern District of California (the "Court") against Sequenom, Inc. ("Sequenom" or the "Company") (NASDAQ: SQNM) on behalf of all persons who purchased or otherwise acquired Sequenom common stock between June 4, 2008 and April 29, 2009.

The Complaint charges Sequenom and its Chief Executive Officer with violations of the Securities and Exchange Act of 1934. The Complaint alleges that defendants misrepresented facts concerning the Company's single most important product under development, SEQureDx, a non-invasive prenatal test for Down Syndrome. Defendants' statements regarding the Company's prospects are alleged to have been materially false and misleading because defendants knew that: (i) the Company's clinical trials were plagued with material defects; (ii) their employees were mishandling the test data and results for SEQureDx; and (iii) the Company would not be in a position to achieve a commercial launch of SEQureDx by June 2009.

On April 29, 2009, Sequenom shocked investors when the Company announced in a press release that its employees had mishandled SEQureDx test data and results. In response to this news, shares of the Company's stock fell by $11.68 per share to $3.23 a decline of more than 75%.

Plaintiff seeks to recover damages for all those who purchased or otherwise acquired Sequenom common stock between June 4, 2008 and April 29, 2009. Plaintiff is represented by Abraham, Fruchter & Twersky, LLP which has extensive experience in securities class action cases, having for example acted as a co-lead counsel in the Peregrine case filed in the Court which recently preliminarily settled for approximately $120 million.
