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.

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 and SGENE Consortium Discover Deletions in the Human Genome Linked to Risk of Schizophrenia

Findings may provide the foundation for a test to complement standard clinical diagnosis, potentially enabling earlier intervention and treatment

A team of scientists led by deCODE genetics has discovered evidence of three rare deletions in the human genome that confer a greater risk of schizophrenia. This discovery shows that individuals who have one of these deletions may be up to 15 times more likely to develop schizophrenia than the population at large. See “Large recurrent microdeletions associated with schizophrenia” which appeared this afternoon in Nature (www.nature.com)

“Schizophrenia is a disorder affecting thoughts and emotions. It is therefore a quintessentially human disease, but one that is little understood biologically and which is difficult to diagnose. These findings are important because they shed light on its causes and provide a first component to a molecular test to aid in clinical diagnosis and intervention. These discoveries also demonstrate one way in which we can use SNP-chips to find rarer genetic factors conferring risk of disease. In many disease areas we have had great success of late in identifying what these chips are best suited to find: common variants conferring relatively modest increases in risk. But we know that individuals with certain mental disorders such as schizophrenia tend to have few children, and thus that we may have to identify a larger number of rare but high risk variants to understand the genetic contribution to susceptibility. It is encouraging that our efforts to use SNP chips to detect rarer variations such as spontaneous deletions and duplications is now bearing fruit,” said Kari Stefansson, CEO of deCODE.

In the recent wave of discoveries of risk variants for common diseases, those associated with mental disorders such as schizophrenia, autism and others have been conspicuously absent. This phenomenon, and the fact that people with these disorders tend to have few children, suggest that rarer and perhaps spontaneously generated variants may account for a greater proportion of the disease burden in these conditions than in others. SNP-chips are not well suited to finding rare SNPs but can, with sufficiently large sample sizes, be used to identify deletions and duplications – known as copy number variations, or CNVs – which can also be carried by healthy individuals in one generation and contribute to risk of disease in the next.
