Interleukin 1B genetic patterns predict life-long tendency to inflammation

and related cardiovascular event risk profile

WALTHAM, Mass., May 1 /PRNewswire-FirstCall/ -- Interleukin Genetics, Inc. (Amex: ILI), today announced publication of the results of clinical studies that support the company's Heart Health Genetic Test to assess cardiovascular risk. The article, titled, "IL1B Gene Promoter Haplotype Pairs Predict Clinical Levels of Interleukin-1beta and C-reactive Protein," was published in the journal Human Genetics (123:387-398; May 2008) and further confirms prior studies associating variations in the Interleukin 1B (IL1B) gene with the inflammatory response.

Sir Gordon W. Duff, M.D., Ph.D., one of the pioneers in the genetics of inflammatory diseases, was the senior author of the paper. Dr. Duff, former Director of the Division of Genomic Medicine, University of Sheffield, UK, commented, "It is now well recognized that inflammation is an underlying factor in many diseases including cardiovascular disease. Interleukin-1beta (IL-1beta) is a major regulator of inflammation. This paper from a collaborative team of international researchers, demonstrates that people with specific variation patterns in the IL1B gene had higher levels of IL-1beta and C-reactive protein (CRP). Studies from our group and others have found that these same IL1B gene variations were associated with an increased risk for cardiovascular disease and an increased risk for myocardial infarction at a younger age, that is, an early first heart attack."

The IL1B gene is among the first gene activated when the body encounters a challenge of almost any type, ranging from bacterial infections to bad cholesterol. IL-1beta initiates a complex cascade of related immune responses. Interleukin Genetics' approach, started over fifteen years ago, is to study variations in regulatory, or on/off switch, regions for these first mover genes and then link them to biological events and risk of inflammatory disease.

Dr. Kenneth Kornman, Chief Scientific Officer at Interleukin Genetics and an author on the paper explained the practical utility of the IL1B genetic information. "We use a simple cheek swab to collect an individual's DNA. Our technologists perform the genetic analysis in our CLIA certified laboratory. A report is generated about an individual's risk for excess inflammation and cardiovascular disease. The privacy-ensured report is sent directly to the individual, who then has access to physicians and genetic counselors to discuss results."

These peer-reviewed results build on prior studies which showed that three gene variations inherited together from a parent, called a haplotype, functioned together to control regulation of the gene producing IL-1beta. In this study, four specific IL1B haplotype pairs, one from each parent, representing just over half of the study population, were associated with higher tissue levels of IL-1beta levels, and two of those haplotype pairs were also associated with increased blood CRP levels. CRP is an inflammatory chemical that is well-established as an independent marker of risk for heart disease.

Interleukin Genetics' Heart Health Genetic Test is available to consumers in the U.S. and Canada under the Gensona(R) brand and marketed by Alticor Inc. The Gensona(R) Heart Health Genetic Test employs a number of single nucleotide polymorphisms (genetic sequence variations called SNPs) to identify specific genetic patterns in the Interleukin 1 genes. These genetic patterns are known to correlate with exaggerated inflammatory responses and increased risk of early cardiovascular disease. The Gensona(R) Heart Health Genetic Test is available in the Personalized Health Products category at Quixtar by e-mail at Quixtar also can be reached at 800-361-2213.

About Cardiovascular Disease

According to the Centers for Disease Control and Prevention, about 700,000 people die annually of cardiovascular disease. Cardiovascular disease involves the heart and vessels and is the number one killer in the U.S. accounting for nearly 30-percent of all deaths. Cardiovascular disease has a number of forms but the most common are myocardial infarction and angina pectoris which affect the heart itself. There are well known environmental risk factors associated with cardiovascular disease such as smoking, diet, inactivity and increased alcohol use. Heredity also plays a factor in cardiovascular disease since other risk factors like high blood pressure and high LDL cholesterol tend to run in families. Cardiovascular disease can be reduced by controlling environmental factors and understanding the genetic factors that put people at greater risk for heart disease.
