Pancreatic cancer has been added to the deCODEme Complete Scan. Pancreatic cancer is a particularly difficult form of cancer. It is virtually asymptomatic in its earliest stages. The cancer typically spreads rapidly and aggressively into surrounding tissue and organs, it is resistant to standard chemotherapy and has a strong tendency to recur. These characteristics make pancreatic cancer one of the most challenging cancers to treat unless caught early enough, and provide a grim prognosis for many diagnosed with the disease.

Currently there is no screening test available for this cancer, but genetic variants have been identified that are associated with increased risk of developing non-endocrine pancreatic cancer, the most common type of pancreatic cancer.  The deCODEme Complete Scan recently added non-endocrine pancreatic cancer to its genetic risk assessment profile.

We have just made some updates to the deCODEme ancestry service. Now you have more power and flexibility when you compare your genome with that of friends or individuals from different populations around the world.

Your genome can be viewed as a mosaic or tapestry made up of fragments of chromosomes from your ancestors. Fragments of chromosomes inherited from very recent ancestors, say grandparents, are expected to be large – typically tens of millions of nucleotides in size. As ancestors become more ancient, then the size of the chromosome fragments inherited from them become smaller – down to a few thousand or hundred nucleotides for ancestors born thousands of years ago.

Our new and improved genome comparison tool enables to you compare your genome with another individual in order to determine which chromosome fragments you share and to see how much of your genome is shared. The fascinating thing about this analysis is that each shared fragment represents a common ancestor. The number of shared fragments and their size reflects the number of common ancestors and how far back in time they are found. In other words, you can see how closely you are related.

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.

Hypertension genetic risk now a part of the deCODEme Complete Scan

Hypertension, commonly referred to as high blood pressure, has been added to the deCODEme Complete Scan. Hypertension is defined as blood pressure of 140/90 mmHg or above on three consecutive measurements at least six hours apart. Blood pressure this high is a risk factor for many diseases. Over time, the increased workload on the heart weakens it and contributes to atherosclerosis (the thickening of the arteries due to fat and cholesterol depositions), thereby increasing the risk of coronary heart disease and stroke, which are among the leading causes of death in the United States. High blood pressure can also lead to other conditions, such as heart failure, kidney disease, and blindness. High blood pressure is especially dangerous because it often has no obvious warning signs or symptoms and can therefore remain undiagnosed and untreated long enough to cause damage. High blood pressure is common, but too often goes undetected. An estimated 1 billion people worldwide have hypertension, and this number is expected to increase to 1.56 billion people by the year 2025. This translates to about 1 in 4 adults being afflicted with hypertension worldwide. Currently, about 1 in 3 Americans are thought to have hypertension, and a third of them probably do not know it.

deCODE scientists have discovered a single SNP that confers increased risk if inherited from the father, but is protective if inherited from the mother

Scientists at deCODE genetics, Inc. publish in the journal Nature the discovery of a version of a common single-letter variant in the sequence of the human genome (SNP) with a major impact on susceptibility to type 2 diabetes (T2D). The impact of the T2D variant is not only large, but unusual: if an individual inherits it from their father, the variant increases risk of T2D by more than 30% compared to those who inherit the non T2D-linked version; if inherited maternally, the variant  lowers risk by more than 10% compared to the non T2D-linked version. Nearly one quarter of those studied have the highest risk combination of the versions of this SNP, putting them at a roughly 50% greater lifetime risk of T2D than the quarter with the protective combination. This is the second largest effect of any genetic variant for T2D apart from SNPs in TCF7L2, discovered by deCODE in 2006.

“We could make this discovery beacause we are in the unique position of being able to distinguish what is inherited from the mother from what is inherited from the father. This we can do because of the large amount of data we have assembled on the Icelandic population. Read the rest of this entry »

Systemic Lupus Erythematosus is a complex disease and often difficult to diagnose – knowing your genetic risk may help your doctor rule out or confirm Lupus.

Systemic Lupus Erythematosus has been added to the deCODEme Complete Scan. Lupus is an autoimmune disease characterized by intermittent flares of inflammation in various tissues of the body. Autoimmune diseases occur when the body’s tissues are attacked by its own immune system. Normally, people produce antibodies that attach themselves to infectious agents when they enter the body and mark them for destruction by the immune system. People who have Lupus produce abnormal antibodies that target tissues within their own body. Lupus can therefore cause inflammation and tissue damage in various organs such as the skin, heart, lungs, kidneys, joints, and even the nervous system. If you already have a deCODEme Complete Scan you can now log in to see your genetic risk for Systemic Lupus Erythematosus. If you want to purchase a genetic test visit the deCODEme store.

The National Human Genome Research Institute catalog can now be accessed through your deCODEme account

Through your deCODEme account (or the demo account if you are not yet a deCODEme customer) you can access a catalog of published Genome-Wide Association Studies (GWAS) that has been compiled by the National Human Genome Research Institute (NHGRI).

This feature allows you to gain a quick overview of where research on common traits has been showing associations with single nucleotide genetic variations (SNPs).  Users can easily select a disease or trait from a list and a feature track with the corresponding SNPs from the catalog will show up in our Genome Browser.

Many of the associations in the GWAS catalog compiled in August 2009 are included in our Health Watch feature. There are also numerous other associations that our scientists have not included, as they do not fulfill the criteria we set for inclusion in our Health Watch.

The GWAS catalog is presented (see here) simply as it appears on the NHGRI web site and has not been reviewed by deCODE’s scientists. The catalog is provided primarily for educational purposes – for the curious George who wants to look at genome-wide association study results in the context of other information that we provide in our Genome Browser.

As a follower of deCodeYou, we wanted to let you know about some important developments in the company and how we believe these will underpin our ability to continue to keep you in the forefront of understanding what the latest advances in genetics mean for you and your health.

For the past several months, deCODE has been working on restructuring its operations. As a result of these efforts, deCODE has entered into and filed concurrently with its Chapter 11 petition announced today an asset purchase agreement under which it would sell its Iceland-based human genetics operation to new owners. This is the subsidiary that conducts our human genetics research, manages our population genetics resources and provides our personal genome scans and DNA-based risk assessment tests. This agreement is subject to a number of contingencies, including a competitive bidding procedure and court approval in accordance with bankruptcy law. It also provides interim financing to enable us to continue operations during the Chapter 11 process, and we have asked the court for the customary authority to continue to provide products and services to our customers without interruption during the bankruptcy process.

Thus you should expect to continue to hear from here on all the latest in human genetics and its relevance to health and healthcare. You can read our press release here.

With best regards,

Knowing your risk for Chronic Kidney Disease through a deCODEme DNA scan can increase your awareness and empower you to take preventive steps to protect your kidneys.

Chronic Kidney Disease has been added to the deCODEme Complete Scan. Chronic Kidney Disease involves the gradual loss of kidney function over time that can ultimately lead to kidney failure. It typically develops as a result of other common diseases, primarily diabetes, high blood pressure and obesity, but not everyone has the same risk of developing Chronic Kidney Disease. Research suggests that this disease has a strong familial component.

In the U.S., an estimated 26 million adults have Chronic Kidney Disease, but most of them do not know it. The kidneys have such a remarkable ability to compensate for problems in their function, that there may be no symptoms of Chronic Kidney Disease until it has progressed considerably.

Recently, scientists identified a common genetic variant (rs4293393-T), associated with increased risk of Chronic Kidney Disease. deCODEme has incorporated these results into the complete genetic scan, which analyzes your DNA and provides you with a personalized risk assessment for Chronic Kidney Disease and about many other diseases, including diabetes, obesity and kidney stones.

Chronic Kidney Disease is a growing problem in the U.S. and in other western parts of the world, Knowing your risk for Chronic Kidney Disease can increase your awareness and empower you to take preventive steps to protect your kidneys.

deCODEme Complete Scan now includes Testicular Cancer

At deCODEme, we believe that when it comes to planning your preventive health efforts, your genetic profile is the place to start. This month we have added two new diseases, both of which are highly curable if caught early.

If you are a deCODEme customer who has bought our Complete Scan, your account now includes a personalized genetic risk assessment for:

Testicular Cancer of males, and Ovarian Cancer of females.

Our scientists have also added more genetic details to the risk assessment for Prostate Cancer, which now includes a total of 25 genetic risk variants for customers of the Complete Scan.

deCODEme DNA test now includes Ovarian Cancer

Ovarian cancer is the eighth most common cancer in women. Based on ovarian cancer statistics in the U.S., it is expected that 1.4% of women born today will be diagnosed with cancer of the ovary at some point during their lifetime. This represents the lifetime risk of ovarian cancer and means that 1 out of every 71 women will be diagnosed with this disease during their lifetime. deCODEme Complete Scan now includes risk calculation for Ovarian Cancer.

deCODEme Prostate Cancer

Last night we announced our discovery of four more SNPs linked to increased risk of prostate cancer. At the same time, academic collagues in the US and UK have also found more SNPs. (See article in TIMES ONLINE) All of the well-validated new risk variants will be incorporated into your deCODEme profile in the days ahead.

In the same study we published yesterday, we also conducted an analysis of all well-validated genetic risk factors discovered to date to establish what percentage of men would be at a significantly higher risk than average using these markers. Based upon our ability to swiftly conduct a population-based analysis in Iceland, this analysis demonstrates that about 4% of men are at more than double average risk based upon these risk factors, while just over 1% are at more than 2.5-times average risk.

deCODEme provides personalized access to some of the first genetic variants recently linked to the most common type of brain cancer - Glioma

There are various types of brain cancer. Brain cancer can be primary, when it starts from cells in the brain, or secondary, when the cancer starts in another part of the body (for example in the lung or breast) and spreads to the brain through the bloodstream (that is through metastasis). Brain tumors can also be either benign (non-cancerous) or malignant (with cancer cells that multiply uncontrollably).

A glioma is a malignant primary brain cancer that originates from so-called glial cells found within the brain. There are several different types of gliomas determined by the type of glial cell that gives rise to the tumor. Although gliomas are rare, they are the most common type of primary malignant brain tumor in adults. They account for up to 80% of all brain cancer cases, with around 21,000 individuals diagnosed every year in the USA.

You may have heard about glioma in the news recently as this was the type of malignant brain cancer that recently claimed Senator Edward M. Kennedy’s life at age 77. The causes of gliomas are largely unknown. However, scientists have long suspected that genes play a role, making some individuals more likely than others to develop brain cancer. Now some of these genes have been found. A study published in Nature Genetics in July, 2009, reports on the identification of the first common genetic variants known to contribute to an increased risk of developing this type of brain cancer. The deCODEme team has reviewed these findings and added them to the deCODEme Genetic Scan . On the basis of this newly published knowledge, we can now provide customers of European descent with a personalized interpretation of their genetic risk for developing a glioma-type brain cancer.

It’s Not Just the Sun: deCODE Discovers Sequence Variants Affecting Susceptibility to Skin Cancer.

Scientists at deCODE genetics and academic colleagues from Europe and the United States today present in the journal Nature Genetics the discovery of common genetic risk factors for basal cell carcinoma (BCC) that affect people with fair and dark complexions alike. deCODE had previously discovered five common single-letter variants in the sequence of the human genome (SNPs) linked to risk of BCC, the most common cancer in people of European descent. However, most of these earlier findings were also correlated with fair skin, well known to accompany vulnerability to the damaging effects of ultraviolet radiation in sunlight. By contrast, three of the SNPs presented today do not correlate with light pigmentation…

deCODE Discovers a Gene Linked to Risk of Kidney Stones and Osteoporosis. Findings offer promising target for drugs to better regulate calcium metabolism, are integrated into deCODEme™.

A discovery by scientists at deCODE genetics and academic colleagues from Iceland, the Netherlands and Denmark has pointed to a common biological mechanism contributing to both kidney stones and decreased bone mineral density (BMD). About 60% of the population carry two copies of a single-letter variation in the human genome (SNP) on chromosome 21, putting them at roughly 65% greater likelihood of developing kidney stones than those who carry no copies. This single variant may thus account for more than a quarter of the incidence of kidney stones, and in women carriers it is also associated with decreased BMD at the hip and spine.

Charles Wallace and his wife believe that a deCODEme Complete Scan helped save Chuck's life when it lead to discovering Prostate Cancer. Click on the picture to see Chuck's story.

Dr. Bradley Bale at the the Heart Attack & Stroke Prevention Center is a big believer in deCODE’s tests for genetic risk factors for cardiovascular disease. As he has for many of his patients, Dr. Bale recommended that Charles Wallace, a 55 year-old Texan, have a full deCODEme scan to understand his risk of a range of conditions, including cardiovascular diseases. The breadth of the risk factors analyzed by deCODEme proved to be very important indeed. Mr. Wallace learned that he was at nearly double the average risk of prostate cancer, a piece of information he and Bale followed up on and that Wallace credits with helping to save his life.

deCODEme calculates your genetic risk for Multiple Sclerosis

The Multiple Sclerosis Association of America (MSAA) encourages Multiple Sclerosis (MS) Awareness during March 2009.

Multiple sclerosis (MS) is the most common neurological disorder diagnosed in young adults.  It is an inflammatory disease of the central nervous system; the brain, nerves and spinal cord, that damages the protective insulation (known as “myelin”) surrounding the nerves. As a result, nerve impulses carrying messages from the brain and spinal cord are disturbed, causing a variety of symptoms such as visual disorders, weakness, dizziness, and various movement disorders, to name but a few.

The causes of MS are not fully understood. With better understanding of the disease, more effective ways will be found to treat it in the future, and hopefully prevent it from occurring in the first place. Significant steps towards better understanding of MS have however been made.

The Map of Kinship can be used not only to learn about your relationship to people from the different continents, but also your relationship to populations within the continents.

From a genetic point of view we are all unique, but some individuals are more similar than others. Generally speaking, genetic differences reflect geography. People from the same geographic area tend to be more genetically similar than people from distant parts of the world. This means that the greater your genetic similarity is to a particular population, the more likely you have ancestors that belonged to that group in the past and relatives in the present.

The deCODEme team has recently implemented a new tool, called the Map of Kinship. This tool can be used to explore a person’s ancestry and genealogical relationship to more than 1000 individuals from 53 populations from all over the world.
