Scientists at deCODE Genetics and academic collaborators from Iceland, the USA, The Netherlands and Spain today report the discovery of variants in the human genome that associate with levels of thyroid stimulating hormone and risk of thyroid cancer. The paper ‘Discovery of common variants associated with low TSH levels and thyroid cancer risk‘ is published today in the online edition of Nature Genetics.

Using data obtained by applying both Illumina whole-genome sequencing technology and Illumina SNP chip technology, deCODE’s scientists performed a genome wide association study on levels of thyroid stimulating hormone (TSH) in 27,758 Icelanders. 22 SNPs with genomewide significance were discovered, of which one, rs965513 had previously been shown to associate with thyroid cancer. The remaining 21 SNPs were genotyped in 561 Icelandic thyroid cancer cases and 40,013 controls. Variants suggestively associated with thyroid cancer were then genotyped in an additional 595 non-Icelandic cases and 2,603 controls.

After combining the results, three separate variants on chromosomes 2q35, 8p12 and 14q13.3 were shown to associate with risk of thyroid cancer, conferring an added risk of 30 – 100%, compared to the general population. These variants were also found to associate with low levels of TSH, a key regulator in the biology and endocrinology of the thyroid gland.

“This study underscores the important role that the genetics of diversity in normal physiologic function can play in understanding the risk of disease. To date, the at-risk alleles of all the variants that confer risk of thyroid cancer associate with decreased serum levels of TSH, suggesting that the primary disorder in non-medullary thyroid cancer is an endocrine one, characterized by decreased concentration of TSH,” said Kari Stefansson, deCODE’s CEO and senior author of the study.

Thyroid Cancer is a malignant thyroid neoplasm, which can be treated with radioactive iodine or surgical resection of the thyroid gland. The contribution of genetics to the risk of thyroid cancer is greater than to any other cancer. Thyroid cancer is classified into four main histology groups: papillary (PTC), follicular (FTC), medullary (MTC), and undifferentiated or anaplastic thyroid carcinomas. The great majority of malignant thyroid tumours are nonmedullary, either PTC (80–85%) or FTC (10–15%).

Scientists at deCODE genetics and academic colleagues from Iceland, China, Sweden, the UK and Australia today report the discovery of the most important single-letter variation (SNP) in the sequence of the human genome yet associated with risk of primary open-angle glaucoma. This is the most common form of glaucoma and a major cause of blindness worldwide.

The SNP on chromosome 7q31 is common among Europeans, with approximately 6% of people of European ancestry carrying two copies of the at-risk version, putting them at roughly 60% greater risk of developing the disease than those who carry none. But among Chinese, the impact of the SNP is markedy different. In study groups from Hong Kong and Shantou, the at-risk version of the SNP is shown to be carried by less than 1% the population, but each copy carried confers a more than five-fold increase in risk. The SNP is near the genes encoding caveolin 1 and 2, membrane proteins that are expressed in the meshwork that drains fluid from the eye, a process that if disturbed can increase pressure on the optic nerve and lead to glaucoma.

“The key to reducing the personal and public health impact of glaucoma is early diagnosis and treatment to slow the loss of sight. Discoveries such as today’s, which follows on our previous landmark findings in exfoliation glaucoma, are important because we can fold them directly into tests to target screening and to detect and treat more disease earlier. Moreover, among Chinese this latest SNP alone can define a small fraction of the population that should be very carefully screened. This underscores the value of being able to systematically analyze the impact of genetic risk factors across continental ancestries. Not only are these markers medically useful, they also tell us a bit about evolution and the spread of humanity across the globe,” said Kari Stefansson, deCODE’s Executive Chairman and President of Research and senior author of the study.

The authors would like to thank the more than 40,000 people who participated in this study, both glaucoma patients and control subjects. The paper, “Common variants near CAV1 and CAV2 are associated with primary open-angle glaucoma,” is published online in Nature Genetics at www.nature.com/ng and will appear in an upcoming print edition of the journal.

Primary open-angle glaucoma is a disease in which the optic nerve becomes damaged, leading to a progressive loss of sight. It affects tens of millions of people worldwide, mostly those over the age of 50. Incidence increases with age and varies between populations. Other known risk factors include high blood pressure and diabetes. Current treatments include eye drops that reduce pressure on the optic nerve, as well as surgery.

deCODE genetics and ARUP Laboratories today announced a partnership  through which ARUP will offer deCODE’s DNA-based prostate cancer risk assessment test  to its clients nationwide.

Under the terms of the non-exclusive agreement, ARUP will integrate deCODE ProstateCancer™ into the portfolio of tests it offers to leading academic medical centers, public and private healthcare providers, and major hospitals across the United States. ARUP’s clients will order the test, submit samples and receive results through ARUP, with deCODE conducting the genetic analysis in its CAP and CLIA-certified laboratory.

deCODE ProstateCancer measures 25 common single-letter variations, or SNPs, in the sequence of the human genome that are associated with the risk of prostate cancer. These SNPs were validated in tens of thousands of patients and controls in many populations. The risk conferred by these common SNPs is independent of family history, and does not correlate with benign prostatic hyperplasia (a non-cancerous enlargement of the prostate). The test can identify approximately 15% of men in the general population who are at double the average risk of prostate cancer as well as 5% who have triple the average risk. This test is complementary to standard clinical risk screening, including PSA, providing additional information for a more complete and personalized picture of individual risk to help doctors manage effective screening and early-detection strategies.

“The management of patients with elevated or borderline PSA continues to be a challenge, and having the additional knowledge of a patient’s genetic risk for prostate cancer can be very useful. We are pleased to be working with deCODE, who has developed this test through a number of large clinical studies and continues to demonstrate excellent scientific productivity in the area of human genetics,” said Edward Ashwood, MD, President and CEO of ARUP Laboratories.

“We are excited to be partnering with ARUP to increase the availability of our prostate cancer test to physicians and their patients. The quality and breadth of their services, and their range of customers across the healthcare spectrum, make them an excellent partner. Our test helps to meet the need for improved risk stratification and patient outcomes, and we believe that this alliance will make these benefits available to a greater number of patients,” said Kari Stefansson, Executive Chairman and President of Research at deCODE.

ARUP Laboratories plans to begin offering deCODE’s prostate cancer risk test (ARUP test code 2003326) to clients in the fall of 2010.

deCODE genetics ehf today emerged as a newly financed, private company focused on advancing the science of human genetics and its application to products and services that improve human health. The new company will be building on the scientific leadership in genetics it developed over more than a decade as a subsidiary of deCODE genetics, Inc. deCODE ehf was this week purchased from its former parent company by Saga Investments LLC, a consortium that includes Polaris Ventures and ARCH Venture Partners, two leading life science investors. deCODE will continue all of its operations and product lines in this field, including its deCODE diagnostics disease risk tests; deCODEme™ personal genome scans; and contract service offerings including genotyping, sequencing and data analysis. Going forward, deCODE  will concentrate on translating its science into medically and commercially important products and services.  The company will be led by a two-man executive committee comprised of Earl “Duke” Collier, previously an executive vice president at Genzyme Corp.,who will serve as CEO, and Kari Stefansson, who will serve as executive chairman and president of research.

deCODE operates the most productive human gene discovery engine in the world. It is driven by genetic and medical data from 500,000 participants from around the globe taking part in its gene discovery work; comprehensive genealogies linking the 140,000 Icelandic participants; a major CLIA- and CAP-certified genotyping and sequencing facility; and statistical and informatics tools for mining large datasets, for maximizing the information derived from genotyping and sequencing data, and for visualizing genetic and disease data in research, in the clinic, and for subscribers to its genome scans.

“deCODE has led the world in discovering variants in the sequence of the human genome that affect the risk of common diseases. Our resources and expertise have also enabled us to develop the leading analytical tools in the field, and we are putting all of this to work to provide unique value for patients, physicians and researchers. As we enter the era of sequencing entire genomes, we believe our ability to make sense of ever larger amounts of data will continue to keep us in the lead in discovery. And with our now solid financial backing and the splendid addition of Duke Collier to our management, we will be taking a lead in the translation of our science into powerful products and services.” said Kari Stefansson.

“I am pleased to be joining Kari and the outstanding scientific team at deCODE,” said Duke Collier. “deCODE combines world class science devoted to human genetics, unmatched access to genetic data, and a powerful set of tools for managing and analyzing this data. SNP genotyping, and now genomic sequencing, is taking human genetics into an ever expanding world of research, discovery and translation. With its scientific skill and industrial scale analytical capacity, deCODE will be an invaluable partner to investigators, labs and companies working at the highest levels of sophistication in this exciting field. I am thrilled by the challenge and the opportunity.”

Scientists at deCODE genetics today report the discovery of seven novel and common single-letter variations in the sequence of the human genome (SNPs) that are involved in modulating the electrical impulses that govern the working of the heart. Two of these SNPs, which correlate with electrocardiogram (ECG or EKG) measurements that are used in the clinical evaluation of heart health and activity, were then shown to confer increased risk of atrial fibrillation (AF), one of the most common causes of irregular heartbeat and a leading cause of stroke. The paper, “Several common variants modulate heart rate, PR interval and QRS duration,” is published online in Nature Genetics and will appear in an upcoming print addition of the journal.

The deCODE team began by correlating ECG measurements with genome-wide SNP data from more than 40,000 Icelandic participants in its gene discovery program. This search identified one novel SNP influencing heart rate and four each linked to PR interval and QRS duration, measurements of how quickly the electrical impulses that cause the heart muscles to pump achieve their purpose. Intriguingly, SNPs on chromosome 3 linked to both longer PR interval and QRS duration are in the gene encoding SCN10A, a sodium channel that has never before been linked to heart activity. Individuals with the same variants were also more likely to have been fittted with a pacemaker. A follow-on analysis of all of the novel SNPs in Icelandic and Norwegian heart patients and controls demonstrated the association of two of the SNPs linked to PR interval to risk of AF, and another SNP to increased risk of advanced atrioventricular block. Two other papers published today in the same journal provide further validation of some of the deCODE findings.

“Over the past two years, we have discovered major genetic risk factors for heart disease and stroke and introduced tests for these risk factors into clinical practice. We are building the power of these tests through our ongoing discovery work, and today’s findings demonstrate again the fruitfulness of using intermediate risk factors and clinical measurements as entry points for finding risk factors for disease. Our population resources enable us to do so efficiently and with exciting results. These latest findings will be incorporated into our deCODE AF test and deCODEme scans,  and certain of these discoveries may also provide opportunities for out-licensing for therapeutic development,” said Kari Stefansson, CEO of deCODE.

deCODE genetics and Celera Corporation have announced the signing of agreements under which deCODE has granted Celera non-exclusive worldwide licenses to deCODE’s genetic markers for increased risk of major cardiovascular and metabolic diseases, including heart attack, stroke, atrial fibrillation (AF) and type 2 diabetes (T2D). These markers can be incorporated into laboratory tests for assessing and managing individual risk of these diseases.

“This is an excellent opportunity to broaden the clinical application and commercialization of our discoveries of high-impact genetic risk factors for major diseases. The markers included in these agreements are among the most widely replicated genetic risk factors for cardiovascular and metabolic disease, and they provide a natural complement to the biomarker services already offered by Berkeley HeartLab, Celera’s subsidiary.  In Celera we have a partner with a global reputation in human genetics and a large and effective outreach and sales force. We are pleased to have the chance to work with them to build upon our discovery and testing platforms and to accelerate the adoption of personalized medicine,” said Kari Stefansson CEO of deCODE.

“We believe access to these highly replicated markers, which complement our internal proprietary genetic discoveries in cardiovascular disease such as KIF6 and LPA, furthers Celera’s commitment to be a leading provider of genetic tests used routinely in personalizing disease management,” said Kathy Ordoñez, CEO of Celera.  “We expect Berkeley HeartLab to incorporate these markers into future laboratory service offerings, and Celera plans to ultimately commercialize them globally as new molecular diagnostic tests through our Products business.  We believe these markers that predict risk of coronary heart disease and drug response could produce highly differentiated, proprietary, and compelling tests that personalize cardiovascular disease management.”

As a deCODEyou reader, you have an active interest in how genetics can help to improve personal health and healthcare. If you are a deCODEme subscriber or have taken one of our DNA-based diagnostic tests, you have already followed up on that interest.

Then again, you may not have had your genome analyzed yet. You may simply be interested in taking part in research, having a scan, or simply in keeping up with the latest discoveries.

But whoever you are, your genome is information about you. And at deCODE, we believe that your genome belongs to you. Over the past decade we have worked with hundreds of thousands individuals who have decided to use their genome to advance our gene discovery work, to understand their risk of a certain disease, or who want to have a broad and constantly updated look at their genome through deCODEme. In every case, we think it is the individual who has the right to decide to use their genome and learn about it as they wish.

Our job is to find the variations in the sequence of the genome that have an impact on risk of disease, and to report to those who use our tests and scans what those findings mean to them. We have done a lot of this – more than anyone else. And because we take your genome as seriously as you do, our tests and scans only detect genetic risk factors that have been validated in multiple populations and to very strict criteria. Many of the risk factors we have found and test for in diseases like heart attack, type 2 diabetes and breast cancer account for a large proportion of the occurrence of these diseases. Some have as big an impact on risk as do some of the major lifestyle and environmental risk factors that are already a standard part of risk screening.

So when we hear august voices argue that you shouldn’t have the right to look at your genome if you want to, or that we shouldn’t test for genetic risk factors until we know everything there is to know about the human genome, we feel obliged to disagree. In this week’s New England Journal of Medicine, we have heard again that it is “too early” to measure genetic risk factors for common diseases. Why? In essence because in the coming years we are likely to discover many more genetic risk factors that will help to round out our understanding of all of the risk factors that exist. To be sure, we will discover more risk variants in a great many diseases. Many will be common but with little effect on risk. Others will be rare but will confer a high likelihood of disease and thus likely be useful components in genetic tests.

But since we already know risk factors that can nearly double the risk of heart attack, diabetes or breast cancer, in a substantial portion of the population, we take the much clearer view that there is an ethical responsibility to make tests for these risk factors available as widely as possible. As our CEO, Kari Stefansson, was cited as noting in the New York Times yesterday, our tests can identify people who are at several times average risk of major diseases, and there is nothing trivial about that sort of increased risk.

After all, we believe that testing for cholesterol is a good thing, even though our understanding of just how LDL impacts risk of heart disease in incomplete. Similarly, we are only now learning how to optimize the use of statins (and that our heart attack risk factor on chromosome 9p21 has been shown to be helpful for finding the best dose for individuals). How many lives would have been lost if we had taken statins off the market until that elusive day when we thought we understood everything about them?

In our view the challenge is rather to try to bring genetic risk factors into clinical practice as swiftly as possible. As an article this week in The Times points out, a deCODEme scan has a lot of actionable risk information in it. But one of the things we need to do is educate doctors about how to use such results  and how to integrate genetic risk into everyday screening. Our own experience with doctors is that most are very eager to learn. Moreover, genetic information complements what they already do and helps them to deliver better and more personalized medicine to their patients.

In the past few years we have made rapid strides in identifying the key genetic risk factors for some of the most common diseases in our society. Very large independent studies have established that detecting these risk factors can help individuals to act to protect their health and to get the treatments that are best suited to them. This is precisely the sort of information that is going to make it possible to transform our healthcare system into one that is both more effective and efficient – focused on preventing disease and treating it early, rather than spending vast sums of money once people are already seriously ill.

You and your genome are already at the heart of this transformation. If someone tells you that you need to wait, or that they will decide whether and what you can learn about yourself, you need to set them straight. We’ll be there with you.

Martha Stewart at the deCODE laboratories

On Thursday, February 5^th, just ahead of Friday’s annual focus on women’s heart health awareness, deCODE CEO Kari Stefansson is scheduled to appear live on The Martha Stewart Show, the nationally syndicated lifestyle series hosted by Martha Stewart. The discussion will focus on how understanding the inherited risk factors measured by the deCODEme™ full genome scan and the new Cardio and Cancer Scans may empower people to better protect their health. Those unable to watch Thursday’s show live can find a replay of the segment on www.marthastewart.com or on www.decodeme.com.

“As the people who discovered the highest impact genetic risk factors for heart attack and stroke, this is our way of encouraging people to gain a better understanding of their cardiovascular risk. Because these diseases occur at the interface between genes and the environment, this is empowering information that may help people to take action to effectively reduce the likelihood of developing these diseases. We are also pleased to have the opportunity to talk about our scans with Martha Stewart in this month devoted to increasing the awareness of heart disease. Heart disease remains the leading killer of women as well as men, but there is a lot we can all do, working on our own and with our doctors, to reduce our risk and to stay healthier longer,” said Kari Stefansson, CEO of deCODE.

deCODE Complete Scan, Cardio Scan and Cancer Scan.

Through deCODEme™, the world’s first retail genome analysis service, deCODE genetics today announced the launch of the first focused genetic scans for assessing personal risk of several major cardiovascular diseases and common cancers. deCODEme Cardio™, which detects genetic risk factors for Heart Attack, Atrial Fibrillation, Peripheral Artery Disease (PAD), and several other conditions, is offered at an introductory price of $195. deCODEme Cancer measures genetic risk factors for Prostate Cancer, Lung Cancer, Bladder Cancer, Skin Cancer and Colorectal Cancers, as well as the common form of Breast Cancer, at an introductory price of $225. Both can be ordered as a bundle for $350.

Focused Genetic Scans offer individuals a new way to better understand their risk of cardiovascular disease and common cancers.

“The common diseases, including cardiovascular conditions such as heart attack and stroke, as well as the common forms of cancer in women and men, result from both genetic and environmental risk factors. We are all familiar with many of the environmental and lifestyle factors that impact our risk of these diseases, and we know that addressing these risk factors can lower our risk of disease. Building on our discoveries of inherited risk factors for these diseases, our goal is to help individuals understand the genetic side of the equation. This is empowering information, that may enable people, on their own or working with their doctors, to make more informed decisions to protect their health. In an age when we are encouraged to take more responsibility for our health, we believe that we should all be able to use understanding of our genome to do stay healthy. deCODEme™ opened the era of the personal genome scan, and deCODEme Cardio™ and deCODEme Cancer™ offer individuals who wish to better understand their risk of particular diseases a focused means of doing so,” said Kari Stefansson, CEO of deCODE.

The scans – deCODEme Cardio™ and deCODEme Cancer™ – build on deCODE’s global leadership in the discovery of common variations in the sequence of the human genome conferring increased risk of common diseases. They combine the latest science and highest quality analysis as only deCODE can. The scans are based on assays custom designed by deCODE scientists to detect the single-letter genetic variations (called SNPs) with the biggest impact on disease risk. These are SNPs validated in large-scale studies by deCODE as well as leading academic research institutions. DNA Analysis is conducted in deCODE’s own CLIA-registered laboratory, one of the largest genotyping facilities in the world. Subscribers have access to genetic counseling. Many deCODE customers have already employed the results of deCODEme and the company’s range of DNA-based risk assessment tests to improve and protect their health. Stories of how deCODE’s products are helping individuals and their physicians to take more control of their health can be found on our blog, at www.deCODEyou.com.

deCODEme Cardio™ measures 8 SNPs associated with the risk of heart attack, intracranical and abdominal aortic aneurysm, stroke and atrial fibrillation, peripherial arterial disease (PAD) and venous thromboempolism. deCODEme Cancer™ measures 29 SNPs associated with risk of prostate, lung, bladder and colorectal cancers, as well as basal cell carcinoma and the common form of breast cancer. Based upon which versions of these SNPs they carry, subscribers will receive a secure online profile presenting their results. Results are presented both in terms of relative risk compared to the general population, as well as absolute lifetime risk, which is the percentage likelihood that an individual will develop a disease in their lifetime, which is their relative risk multiplied by the average lifetime risk in the population.

The results also explain what other risk factors interact with genetic risk to increase or decrease the likelihood of developing a given diseaese, as well as how subscribers may wish to follow up with their doctor to optimize the prevention or early detection of these diseases. deCODEme offers genetic counseling to all its subscribers, and deCODE counselors can be consulted via email or by telephone.

Iceland was mainly settled by Scandinavian men and women from Irealand and Scotland

In a paper published today scientists at deCODE genetics present the results of the largest study of ancient DNA from a single population ever undertaken. Analyzing mitochondrial DNA, which is passed from mother to offspring, from 68 skeletal remains from approximately 1000 years ago, the study provides the most detailed look to date at how a contemporary population differs from that of its ancestors. The results confirm previous deCODE work that used genetics to test the history of Iceland as recorded in the sagas.

Audio link:  Dr. Kari Stefansson interviewed on BBC WORLD. BBC

These studies demonstrated that the country seems indeed to have been settled by men from Scandinavia – the vikings – but that the majority of the original female inhabitants were from the coastal regions of Scotland and Ireland, areas that regularly suffered raids by vikings in the years around the settlement of Iceland 1100 years ago.

Perhaps the most remarkable finding of the study published today is that the gene pool of contemporary Icelanders appears to have evolved rapidly over the intervening thousand years. As a result, the original female settlers are genetically more closely related to the present day populations of Scotland, Ireland and Scandinavia, as well as those of northwestern Europe and even southwestern Europe, than they are to present day Icelanders. This is an important demonstration of a phenomenon known as ‘genetic drift.’ In essence, in any population certain individuals will have more offspring and, by chance and in this case over the course of 35 generations, many more descendants than others. And as a result, particularly in a small population, the genetic variety of the original population can decrease and change over time. In this study only mitochondrial DNA was studied, but the same phenomenon applies to the Y chromosome, which is passed from fathers to sons, and to any other part of the genome. The paper, ‘Sequences from first settlers reveal rapid evolution in Icelandic mtDNA pool,’ is published today in the open-access journal PLOS Genetics.

“This study is a major contribution to the use of ancient DNA studies in tracing the history not just of single populations, but of our species and how we spread from Africa to every corner of the globe. It is the first such study to be large enough to permit meaningful statistical methods to be applied to ancient DNA. We very much hope this will aid and encourage others to follow with large studies in other parts of the world. In this field, as in the genetics of common diseases, we are pleased and proud to be able to put the knowledge we gain in Iceland to work for the benefit of people everywhere,” said Kari Stefansson, CEO of deCODE.

Reykjavik, ICELAND, December 8, 2008 – deCODE genetics (Nasdaq:DCGN) today announced the discovery by an international consortium of scientists from deCODE and major European and US academic institutions of a single letter variation in the human genome (SNP) that is associated with increased fasting glucose levels and risk of type 2 diabetes (T2D). deCODE will employ its CLIA-registered genotyping laboratory and existing testing platform to swiftly integrate the finding into its deCODEme™ personal genome scan, and to assess the addition of this new variant to the company’s deCODE T2™ reference laboratory test for assessing individual risk of type 2 diabetes.

The multinational study analyzed a number of SNPs that had been suggestively linked with fasting glucose levels in several major studies involving some 36,000 individuals from Europe and the United States.The analysis identified a version of single SNP within the gene encoding melatonin receptor IB (MTNR1B) that was associated with notable increase in fasting glucose levels. The deCODE team then demonstrated in its Icelandic cohort that this SNP also associated with an increased risk of T2D, a finding that was then replicated in a meta-analysis of data from more than 80,000 cases and controls from Europe and the US. Approximately 10% of the participants in this study carry two copies of the at-risk version of this SNP, putting them at more than 15 percent greater risk of type 2 diabetes than individuals who carry no copies. The paper, entitled “Variants in MTNR1B influence fasting glucose levels,” is published today in the online edition of Nature Genetics, and will appear in an upcoming print edition of the journal.

“This finding is another step towards rounding out our understanding of the genetic factors that underpin glucose regulation and risk of type 2 diabetes. This variant does not confer sufficient risk to be of clinical utility on its own. But when measured in addition to our TCF7L2 variant that is the anchor of the deCODE T2™ test, it may, like other common variants conferring modest risk, enable the test to capture an even larger proportion of inherited risk. We are currently evaluating its integration into deCODE T2™, because understanding genetic risk of T2D enables individuals and their physicians to focus, personalize and improve prevention. In the meantime, we will be enabling our deCODEme subscribers to check their profiles for this new variant, keeping them at the cutting edge of human genetics” said Kari Stefansson, CEO of deCODE.

Type 2 diabetes: A major public health problem
T2D is a chronic condition that develops when the body either becomes resistant to or doesn’t secrete enough insulin. Diabetes affects nearly 200 million people worldwide and, according to the American Diabetes Association, some 21 million in the United States. The vast majority of these have T2D, and as many as one third of Americans with diabetes may not even be aware that they have the disease. More than 50 million Americans have pre-diabetes, a condition characterized by elevated blood glucose levels and which puts these individuals at high risk for developing T2D. T2D can be managed and – most importantly – prevented. If losing weight, eating better and getting adequate exercise aren’t enough, there are also medications that can help to manage blood sugar levels and insulin response to reduce the likelihood of developing diabetes. For more information on T2D and how to prevent it, you can go to the American Diabetes Association’s website.

deCODE Breast Cancer enables women to understand whether they may benefit from more intensive screening, monitoring or preventive drug therapy.

Reykjavik, ICELAND, October 8, 2008 – deCODE genetics today announced the launch of deCODE BreastCancer™, a new tool for assessing risk of the common forms of breast cancer. For the first time, a woman concerned about breast cancer can speak with her physician about a genetic test to better understand her lifetime risk of developing the common forms of the disease.

The common forms of breast cancer result from the interplay of genetic as well as environmental and lifestyle factors and represent 95 percent of all breast cancers. These are distinct from the rare and essentially purely inherited forms of the disease due to mutations in the BRCA1 and BRCA2 genes, which cause between 1 and 3 percent of breast cancers. deCODE BreastCancer™ is a DNA-based reference laboratory test performed using a simple blood sample or cheek swab, ordered by physicians on behalf of their patients.

“This test is simple and compelling because it provides a woman and her doctor a means of understanding her personal risk of developing the common forms of breast cancer. This information is well-validated, relevant to the vast majority of women, and independent of family history and other known risk factors. Combined with the high public awareness of the importance of screening, advances in magnetic resonance imaging (MRI) technology and the availability of preventive drugs targeting estrogen receptors, I believe this test will help to save lives,” said Dr. Kari Stefansson, M.D., Dr. Med., CEO of deCODE.

“DNA-based breast cancer risk assessment has to date been focused on detecting rare mutations that confer very high risk of early onset breast cancer. These are very valuable tests, but they do not measure genetic risk of the common forms of the disease.  The DNA markers identified recently by deCODE represent an important step toward filling current gaps in our understanding of breast cancer risk.  Ultimately, the goal is to deliver more personalized prevention and treatment for a much greater number of women,” said Rebecca Sutphen, M.D., Clinical Geneticist at Moffitt Cancer Center and Advisory Board member at Informed Medical Decisions, Inc., a network of genetic counselors who provide support to physicians and patients using deCODE’s tests.
“We speak to many people who are concerned about breast cancer through our 24/7 YourShoes Breast Cancer Support Center,” said Margaret C. Kirk, CEO, Breast Cancer Network of Strength (formerly known as YME National Breast Cancer Organization). “We are very interested in all advances that could empower people to take charge of their health care and better understand their risk for developing breast cancer.”

Owen Winsett, M.D., founder and director of the Breast Center of Austin, Texas, commented: “I have followed closely the recent scientific discoveries that are incorporated into this test. I am excited to be able to extend my screening and prevention practice, because this test applies to so many more women than the BRCA1 and BRCA2 tests. My patients are eager for this type of risk information and appreciate that the test can be done with a painless inner-cheek swab. I have ordered several tests on an early-access basis and plan to make this test a standard tool for helping me to decide which of my patients may benefit from screening at an earlier age, breast MRIs, and other risk reduction measures. This test helps define individual prevention, which is what so many of my patients want.”

The deCODE BreastCancer™ test measures seven widely replicated single-letter variations (SNPs) in the human genome that deCODE and others have linked to risk of breast cancer. These SNPs contribute to the incidence of an estimated 60 percent of all breast cancers. The test integrates data from discovery and replication studies published in major peer-reviewed journals and involving nearly 100,000 breast cancer patients and healthy volunteers from many populations, principally of European descent. deCODE and other organizations are conducting replication studies to validate these markers in populations of other continental ancestries.

Women taking the deCODE BreastCancer™ test will receive a numerical score representing their relative risk of developing breast cancer in their lifetime compared to that of the general population as well as their personal lifetime risk. According to the American Cancer Society, average lifetime risk for women of European descent is 12 percent. Test scores range from 4.0 times average lifetime risk to less than half, or 0.4-times. The risk assessed by deCODE BreastCancer™ is independent of conventional risk factors such as family history of breast cancer in close relatives, age at first menstrual period, pregnancy history, and breast density. Therefore, this genetic risk should be viewed in the context of other risk factors assessed by a woman’s physician.

deCODE BreastCancer™ can identify the roughly 5 percent of women who are at a greater than 20 percent lifetime risk of the common forms of breast cancer (about twice the average risk in the general population), and the 1 percent of women whose lifetime risk is roughly 36 percent (about three-times average). According to ACS guidelines, women with a lifetime risk of 20 percent or greater should receive annual MRI breast screenings in additional to mammograms, and women at 15 to 20 percent lifetime risk should talk with their doctors about the benefits and limitations of adding MRI screening to their yearly mammogram. With the information provided by the deCODE BreastCancer™ test, an additional 15 percent of women may fall within this range of moderately increased risk.

The test also predicts which women are more likely to develop ER-positive breast cancer if they develop cancer at all. This is important because these women may be more likely to respond to prevention strategies with drugs like tamoxifen that target estrogen receptors. The American Society of Clinical Oncology (ASCO) recommends that women with a five-year risk of 1.66 percent or greater should be considered for preventive treatment with tamoxifen.

deCODE BreastCancer™ may also be used to modulate the risk profile of the early onset inherited forms of breast cancer in women who have tested positive for risk variants in the BRCA1 or BRCA2 genes.

How to order deCODE BreastCancer™
Additional information and physician order forms for deCODE BreastCancer™ can be found at www.decodebreastcancer.com. The price of the test is $1625 dollars and deCODE facilitates filing for reimbursement with commercial insurers. Testing is performed in deCODE’s CLIA-registered laboratory, which has analyzed the genomes of hundreds of thousands of people from around the globe.

Breast cancer is the most common cancer and the second leading cause of cancer deaths among women, according to the World Health Organization. The ACS estimates that 182,400 new cases of invasive breast cancer will be diagnosed in the United States in 2008, resulting in more than 40,000 deaths.

Breast cancers are classified as ER-positive or ER-negative according to whether tumors are found to contain estrogen receptors. In women of European descent, approximately three-quarters of breast cancers are ER-positive, and in women of African descent, approximately 50 percent are ER-positive.

Although a substantial portion of risk of breast cancer is inherited, it has taken painstaking research to find genetic variants predisposing to the disease’s common forms. The mutations in the BRCA1 and BRCA2 genes conferring very high risk have a less than 0.5 percent frequency in the general population in the United States and Europe, accounting for only 1-3 % of all breast cancers.

Identifying and enabling the detection of a substantial proportion of the genetic risk for the common forms of breast cancer is the goal of deCODE’s gene discovery work in breast cancer and the deCODE BreastCancer™ test. Women who know they are at a higher than average risk of breast cancer can also make proactive lifestyle changes to lower their lifetime risk, according to ACS. These include staying physically active, maintaining a healthy weight, eating healthy foods, and limiting alcohol intake and smoking.

Through its CLIA-registered laboratory, deCODE is offering a growing range of DNA-based tests for gauging risk and empowering prevention of common diseases, including deCODE T2™ for type 2 diabetes; deCODE AF™ for atrial fibrillation and stroke; deCODE MI™ for heart attack; deCODE ProCa™ for prostate cancer; deCODE Glaucoma™ for a major type of glaucoma; and deCODE BreastCancer™ for the common forms of breast cancer. deCODE is delivering on the promise of the new genetics.

Urinary bladder cancer is something many people have never heard of. But it is the sixth most common form of cancer in the United States, and its environmental risk factors include exposure to toxic chemicals, including some used in industrial processing as well as cigarette smoke. Genetic factors also play a role and may help to elucidate how bladder cancer starts and develops.

Today, deCODE’s cancer group and colleagues at Radboud University in the Netherlands report the discovery of two single letter variants (commonly referred to as SNPs) in the human genome that confer increased risk of bladder cancer. Both are common, and 20 percent of people of European descent carry two copies of the highest impact SNP, located on chromosome 8q24. That puts them at about 50 percent higher likelihood of developing bladder cancer than people who do not carry the variant.

Since risk screening for bladder cancer has been largely confined to those with known exposure to carcinogenic substances, the ability to test for these variants may useful particularly for those know to have other risk factors. As with all our discoveries, we have worked hard to publish them and to secure intellectual property rights to enable us to put these findings straight to use. deCODE has integrated these findings into deCODEme, so that individuals and their doctors can utilize these findings if it is warranted.

Another intriguing aspect of the paper published today in Nature Genetics is that over the past year deCODE and others have linked SNPs on the same stretch of chromosome 8 to risk of prostate, breast and colorectal cancer. We are looking into what common processes may be triggered or affected by these variants, since a common mechanism might be able to tell us something about the underlying molecular causes of cancer in general.

deCODE and Radboud University Discover Common Variants in the Human Genome Conferring Risk of Bladder Cancer

Detection may be used to complement and target screening for the disease; findings will be integrated into the deCODEme™ personal genome scan.

Reykjavik, ICELAND, September 14, 2008 – Scientists at deCODE genetics (Nasdaq:DCGN) and colleagues at Radboud University Medical Center in the Netherlands today report the discovery of two common single-letter variants in the human genome (SNPs) that confer increased risk of urinary bladder cancer. Approximately 20% of people of European descent carry two copies of the first variant, a version of a SNP on chromosome 8q24, putting them at a 50% higher risk of developing bladder cancer than those without the variant. Individuals who carry two copies of a common version of another SNP on chromosome 3 were found to be at a 40% higher risk of the disease than non-carriers. These are the best-replicated genetic variants ever linked to bladder cancer risk, and the study analysed genotypic data from more than 40,000 patients and controls from Iceland, the Netherlands and eight other European countries. The paper, entitled ‘Sequence variant on 8q24 confers susceptibility to urinary bladder cancer,’ will appear today in the online edition of Nature Genetics at www.nature.com/ng.

“In all cancers, the ability to identify individuals at high risk, screening them intensively and intervening early, is the key to improving prevention and outcomes. We expect that the detection of these and other risk variants will soon be employed to complement the assessment of standard risk factors for bladder cancer. As with all of our discovery work, we seek to publish our findings and establish a solid intellectual property position in order to bring these swiftly into the healthcare arena, and have already folded today’s findings into our deCODEme™ personal genome analysis service. At the same time, we are working to identify the common thread of variants we and others have discovered on chromosome 8q24 that confer risk of several forms of cancer, including prostate, breast, colorectal and now bladder. If a common molecular mechanism exists, it could provide an important insight into oncogenesis more broadly,” said Kari Stefansson, CEO of deCODE.

For a more detailed discussion of today’s findings you can watch a video discussion between Dr. Stefansson and Dr. Simon Stacey on our blog, at www.decodeyou.com.

Urinary bladder cancer is the sixth most common type of cancer in the United States. It is estimated that 68,810 individuals will be diagnosed with bladder cancer in the United States during 2008 and that 14,100 people will die of the disease. Bladder cancer has been linked to exposure to various types of toxic substances such as cigarette smoke and industrial chemicals. Although it has been known for some time that genetic factors also play a significant role, identifying validated genetic risk variants had been problematic. Incidence of bladder cancer varies considerably between ethnicities, and as the risk factors reported here were discovered by analysing DNA from groups of European descent, it is our hope that the publication of these findings will contribute to the swift analysis of the impact of these variants in cohorts of other continental ancestries.

The authors wish to thank the thousands of patients and control subjects who participated in this study, and acknowledge the assistance of national cancer registries that worked to identify potential participants. Data and sample collection in Iceland and the Netherlands was funded in part by European commission grants LSHC-CT-2005-018827 and LSHM-CT-2004-005166.

Science journalist Boonsri Dickinson

Discover magazine reporter Boonsri Dickinson recently tried out deCODEme, as well as two other genetic scans offered by California-based websites. She discusses her results, and talks to several people who question whether genetic scans should be available to the public. Dickinson seems to be happy she had the chance to take a look at her genome, and went over her results with deCODE CEO Kari Stefansson. She notes that as “deCODE is known for discovering genetic risk factors…I decided to use deCODEme to validate the other two,” concluding that “deCODE genetics was authoritative.” Her article, ‘Inside Out: A DNA Diary,’ appeared on newsstands in August and can be found on the Discovermagazine.com website.

As the founder and CEO of deCODE, I want to welcome you to our blog, deCODEyou. This is a place where you can learn not just about deCODE’s discoveries and products but what others are saying about our work and about the application of human genetics to healthcare. We also hope that it will become a place where we can hear from you.

We are at a fascinating juncture in the application of genetics to the practice of healthcare. When we set out to try to search for the genetic causes of common diseases more than a decade ago, we took the approach that what we were doing was fundamentally a data mining challenge. We were trying to find correlations between two datasets: diseases or other phenotypes on the one hand, and variations in the sequence of the human genome on the other. This was a task for which computers were ideally suited. This fundamental insight has served us well, and as we assembled very large population-based datasets on disease, genotypes, and genealogy, advances in genotyping technology, computing power and our own data mining algorithms have enabled us to discovery major genetic risk factors for dozens of the biggest public health challenges of our time.

The purpose of understanding the genetics of disease was to use that information to create new means of diagnosing, treating and preventing disease.

As you know, one of the things we at deCODE are focused on now is turning our discoveries into tests for better assessing individual susceptibility to many common conditions, and, through our pioneering genome analysis service deCODEme™, enabling individuals to put themselves in the context of all that we are learning about human genetics.

And once again, the technology is helping us to bring understanding of genetics to people around the world. Unlike a large number of other companies hoping to follow on our heels, deCODEme is not just a website that happens to be about human genetics; it is your portal into the world’s largest and most successful effort to understand the inherited risk of the most common diseases in contemporary society. And the same technology that enables us to give deCODEme subscribers a secure, constantly updated profile of how you fit into what we are learning about the genome, also enables us to launch this blog and to engage you in a conversation about how we should use this information as individuals, healthcare systems and societies, to make our lives healthier and more productive.

As we make discoveries we are, by definition, opening up new possibilities and breaking new ground. We are very excited to be at the forefront of this work and hope that you will join us in this conversation.

Yours truly,

Kari Stefansson

In its work on the inherited components of dozens of common diseases, deCODE has discovered gene variants that significantly affect individual susceptibility or protection against disease. In the common forms of these conditions – such as obesity, type 2 diabetes and cardiovascular diseases – deCODE has previously shown that genetic variants confer increased or decreased risk by up-regulating or down-regulating the activity of major biological pathways.

In today’s paper, the deCODE team and collaborators from Merck demonstrate one of the principal ways in which the activity of biological pathways is functionally perturbed in a quintessentially complex condition: obesity.

Kari Stefansson, CEO of deCODE, put the study into context: “One of the observations we have made in our work on the isolation of disease genes is that the genetic risk of common diseases is often conferred by variations in the sequence of the genome that affect expression of genes. Hence, one of the ways to approach the study of common diseases is through the analysis of gene expression. This paper provides a substantial contribution towards the understanding of gene expression in man and one example of how it can be used to expand our knowledge of one disease, namely obesity.”
