Sequenom (Nasdaq: SQNM) is very pleased to note the publication in the British Medical Journal (BMJ 2011;342:c7401) of a groundbreaking international study led by our longstanding collaborator, Professor Dennis Lo of The Chinese University of Hong Kong. Building on early work from the Lo laboratory, the present paper is the first report of a large-scale clinical study that validates a noninvasive, plasma DNA-based approach for prenatally detecting Down's syndrome (T21). Sequenom congratulates the research team for their achievements.
