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.

The deCODEme team has been busy working to update and improve your deCODEme experience.  Additions include ABO blood types, Kidney stones, Eye color and Statin-induced myopathy. We have also added  a section for feedback and research and a more detailed Male line analysis.

Here is a summary of the additions and changes:

The Killer In You

60 Minutes Australia recently visited the deCODE genetics labs in Iceland and interviewed deCODE’s CEO Dr. Kari Stefansson. Among the people who did the deCODEme genetic test were journalist Liz Hayes, world surfing champion Layne Beachley and Australian television’s favorite builder, Scott Cam.

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.

deCODEme takes on Heart Disease in February

February is American Heart Month. With heart disease being the leading cause of death in the United States it is important to assess your genetic risk of developing Cardiovascular conditions. To mark this we have decided that during the month of February our deCODEme Cardio Scan™ will be offered for a promotional price of $100.

deCODEme Cardio Scan enables individuals to better understand their inherited risk of heart attack, stroke and atrial fibrillation, intracranial and abdominal aortic aneurysm, and venous thromboembolism.

Genetics contribute to the risk of Coronary heart disease and heart attacks

Coronary heart disease is a progressive disease that begins early in life but symptoms generally do not appear until middle age or later. Coronary heart disease is the main cause of death in the developed countries and it is estimated that over 1.35 million North Americans will as a result of coronary heart disease, have a heart attack in the year 2008.

Several studies have found evidence of a genetic contribution to CHD and heart attacks. Two common genetic variants have been discovered that are associated with an increased risk of heart attack; one variant near the CDKN2A/2B genes on chromosome 9 and another in the CELSR2/PSRC1 genes on chromosome 1. The variant near the CDKN2A/2B genes is a particularly strong risk factor for early-onset heart attacks (occurring earlier than 50 years of age in men and 60 years of age in women).

Adopting a heart-healthy lifestyle can reduce risk

Even though age, gender, and family history are unmodifiable risk factors for coronary heart disease and heart attacks, the risk of developing CHD and eventually a heart attack can be reduced with a lifestyle that includes physical activity, a heart-healthy diet, and no smoking.

Tapping the vast resources of deCODEme scientists

The users of deCODEme show great interest in their results and are not afraid to ask questions. deCODEme customer support welcomes all questions and inquiries and taps the vast knowledge base and resources of its research teams to respond to all emails as comprehensively and quickly as possible. Among the more general questions we receive is the following.

Question
“I’m seriously thinking about doing the DNA test. Now I only have to decide from which company. How does your test compare with tests from other companies?”

On October 8th MSNBC published an article by Arthur Caplan, Ph.D. on genetic tests for breast cancer.
The following is a response by Jeff Gulcher, M.D., Ph.D, Chief Scientific Officer at deCODE Genetics.

Arthur Caplan stresses caution in the application of the new genetic risk tests for common diseases and I certainly agree that genetic testing should be applied with care. However, he goes too far when he says that the new deCODE BreastCancer genetic risk test is only useful for women who have two or more close relatives with breast cancer, is not based on large enough studies to be accurate, and is not regulated.

There are two major types of breast cancer: the rare, early onset form that occurs in certain families and for the detection (for which the Myriad Genetic test is well suited), and the common form which accounts for 95 percent of breast cancer. The vast majority of women who develop breast cancer do not have the conventional risk factors of family history, pregnancy history or breast density. Unfortunately, many of these women were likely considered to be of average risk before their cancer was found. Therefore, they were not even offered screening with breast MRI which detects two to three times more cancer at an earlier stage than mammography alone, or preventive measures such as tamoxifen treatment which can cut down cancer rates by 40 to 50%.

In a recent interview Dr. Kari Stefansson, C.E.O. of deCODE genetics talked about the future for genetic tests such as deCODEme and how he believes that they will drive the shift from intervention to prevention in medicine

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.
