Celera Identifies FCAR Genetic Polymorphism Associated with Increased Risk for Myocardial Infarction

Individuals With FCAR Genetic Polymorphism Derive Better Than Average Protection from Statin Therapy

Study Confirms Genetic Basis for Individuals at Elevated Risk for Heart Attack Who Derive Better Than Average Protective Benefits of Statin Treatment


ROCKVILLE, Md.--(HSMN NewsFeed)--Celera Genomics (NYSE:CRA ), an Applera Corporation business, today announced a publication describing a genetic polymorphism in the gene encoding the myeloid IgA Fc receptor, the FCAR Asp92Asn polymorphism, associated with increased risk for myocardial infarction (MI) and coronary heart disease (CHD). These results were obtained in genetic studies of two separate prospective randomized clinical trials assessing the effect of pravastatin on prevention of MI and CHD: the Cholesterol and Recurrent Events study (CARE) and West of Scotland Coronary Prevention Study (WOSCOPS). The risk of coronary events associated with the FCAR Asp92Asn polymorphism in both CARE and WOSCOPS was independent of other known risk factors. Further, the publication also reported that the increased risk of MI and CHD associated with this polymorphism could be significantly reduced in individuals that were treated with pravastatin, a lipid-lowering compound with anti-inflammatory properties. This paper will appear in the December 2006 edition of Arteriosclerosis, Thrombosis and Vascular Biology, and is currently available on the publication's website at http://atvb.ahajournals.org/.

The CARE study was led by Frank M. Sacks, M.D., Professor of Cardiovascular Disease Prevention, Harvard School of Public Health and Harvard Medical School. The WOSCOPS study was led by Professor James Shepherd, Department of Biochemistry, University of Glasgow and Royal Infirmary.

"This study is among the first to describe genetic polymorphisms that could identify individuals who are not only at greater risk for coronary heart disease and heart attacks, but who also derive significant benefit from preventative statin treatment," said Dr. Sacks. "This genetic information increases accuracy of identifying people who are at high risk of heart attacks, and whose risk can be lowered by statin therapy. Our findings also suggest a new link between the immune system and cardiovascular disease."

The genetic association studies were performed with samples from the male subjects of the CARE trial (2,523 men) and with samples from the all-male WOSCOPS trial (1,562 participants in a nested case control study). The subjects carrying the 92Asn allele in the FCAR gene had 68% higher incidence of MI in CARE and 49% higher risk of CHD in WOSCOPS compared to noncarriers. This genetic information appears to complement traditional risk factors because these risk levels remained similar after adjustment for traditional risk factors including subject's age, baseline LDL-C ("bad" cholesterol) levels, baseline HDL-C ("good" cholesterol) levels, and history of smoking, hypertension, and diabetes. The risk estimates for the FCAR polymorphism were similar in magnitude to risk estimates for smoking. Pravastatin treatment reduced the absolute risk in carriers of the FCAR risk allele by 10% and 4% in CARE and WOSCOPS, respectively. To put these numbers in perspective, when male patients were not stratified by genotype, absolute risk reduction was 2.8% in CARE and 2.5% in WOSCOPS. Approximately 14% of the subjects in these research studies carry the FCAR risk allele.

Investigation of other polymorphisms in the FCAR region indicated that the FCAR Asn92Asn polymorphism was the most likely reason for the observed association of this region of the genome with risk and response. The FCAR polymorphism is located in a region that encodes the IgA-binding domain of the myeloid IgA Fc receptor, also referred to as CD89. The involvement of the myeloid IgA Fc receptor in monocyte activation is consistent with a functional role for this receptor in the pathogenesis of cardiovascular disease.

"This is an exciting discovery and coupled with others that we've made in cardiovascular diseases, contributes to a better understanding of the etiology of heart disease, and helps identify individuals who are more likely to reduce risk by taking a statin as preventative treatment," said Thomas J. White, Ph.D., Chief Scientific Officer at Celera. "Moreover, along with genetic variation in known drug targets and metabolizing enzymes," genetic markers that predict risk for disease may provide a new source of biomarkers for predicting drug efficacy in multiple diseases."

The lead author of the current study was Olga A. Iakoubova, M.D., Ph.D., Project Leader at Celera, and this research study was conducted with collaborators at Harvard Medical School and Harvard School of Public Health, Boston, MA, University of Glasgow and Royal Infirmary, Glasgow, United Kingdom, and Bristol-Myers Squibb Pharmaceutical Research Institute.

About Applera Corporation and Celera Genomics

Applera Corporation consists of two operating groups. Celera Genomics is primarily a molecular diagnostics business that is using proprietary genomics and proteomics discovery platforms to identify and validate novel diagnostic markers, and is developing diagnostic products based on these markers as well as other known markers. Celera Genomics maintains a strategic alliance with Abbott for the development and commercialization of molecular, or nucleic acid-based, diagnostic products, and it is also developing new diagnostic products outside of this alliance. Through its genomics and proteomics research efforts, Celera Genomics is also discovering and validating therapeutic targets, and it is seeking strategic partnerships to develop therapeutic products based on these discovered targets. The Applied Biosystems Group serves the life science industry and research community by developing and marketing instrument-based systems, consumables, software, and services. Customers use these tools to analyze nucleic acids (DNA and RNA), small molecules, and proteins to make scientific discoveries and develop new pharmaceuticals. Applied Biosystems' products also serve the needs of some markets outside of life science research, which we refer to as "applied markets," such as the fields of: human identity testing (forensic and paternity testing); biosecurity, which refers to products needed in response to the threat of biological terrorism and other malicious, accidental, and natural biological dangers; and quality and safety testing, for example in food and the environment. Applied Biosystems is headquartered in Foster City, CA, and reported sales of over $1.9 billion during fiscal 2006.
