SAN DIEGO, Feb. 4, 2013

SAN DIEGO, Feb. 4, 2013 /PRNewswire/ -- Sequenom, Inc. (NASDAQ: SQNM), a life
sciences company providing innovative diagnostic testing and genetic analysis
solutions, announced today that the MaterniT21™ PLUS laboratory-developed test
(LDT) available exclusively through Sequenom Center for Molecular Medicine
(Sequenom CMM) will now report as additional findings the presence of certain
fetal sex chromosomal aneuploidies, in addition to its identification of
autosomal aneuploidies for chromosome 21 (associated with Down syndrome),
chromosome 18 (associated with Edwards syndrome), and chromosome 13
(associated with Patau syndrome). Reporting of these sex aneuploidies will
begin for samples received as of Monday, February 4, 2013.

The test will report on the presence of four rare aneuploidies involving an
abnormal number of X or Y chromosomes, including female syndromes 45,X (Turner
Syndrome) and 47,XXX (Triple X Syndrome), and male syndromes 47,XXY
(Klinefelter Syndrome) and 47,XYY. Results of the blinded clinical validation
study set have been submitted for publication in a peer-reviewed journal.

"Sex chromosome abnormalities may be recognized at birth, as part of the
spectrum of less severe chromosome abnormalities. They can also be found in
adults, many being incidentally discovered in the course of evaluating
patients for infertility or endocrine problems. Identifying these conditions
through the MaterniT21 PLUS test will allow the health care provider and
patient to discuss the medical issues associated with these conditions as well
as to develop both short- and long-term care plans," said Allan Bombard, MD,
Sequenom's Chief Medical Officer.

The MaterniT21 PLUS test analyzes the relative amount of 21, 18, 13, as well
as X and Y chromosomal material in cell-free DNA. The test is intended for
use in pregnant women at increased risk for fetal aneuploidy and can be used
as early as 10 weeks' gestation. Estimates suggest there are about 750,000
pregnancies at high risk for fetal aneuploidy each year in the United States.
The MaterniT21 PLUS test is available exclusively through the Sequenom Center
for Molecular Medicine (Sequenom CMM) as a testing service provided to
physicians. To learn more about the test, please visit www.Sequenomcmm.com.
