As we all know to well, for decades the scales have been tipping in favor of obesity. The epidemic of obesity in many industrialized countries has been driven by many factors, including easy access to fast food, an increasingly sedentary lifestyle, insufficient daily physical activity. All of this while our genomes have evolved on a background of scarcity, often putting a premium on the ability of the body to turn food into fat and store energy for leaner times. A paper published today by deCODE scientists and academic colleagues from the US and Europe provide a significant advance in our knowledge of the underlying genetics and biology of obesity, providing new information for understanding and addressing obesity and perhaps nudging the scales the other way.

New genetic variants influencing Body Mass Index, Weight, and risk of Obesity
deCODE launches deCODE BreastCancer™, a genetic test to screen for risk of the most common forms of breast cancer

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.

Your genome, your choice: a buyer’s checklist for genetic tests

Scientists at deCODE genetics Genetic Service Facility lab in Iceland
The number of companies offering genetic tests to the public is large and growing. But there are vast and very real differences in the quality, purpose and price of testing services out there. So how do you tell the difference between them? And how do you decide which to use?
Knowing what you want
First and foremost, you need to think about what sort of information you hope to gain from your genome and how accurate you want the results to be. Are you taking the test only for fun, perhaps hoping to talk about your results on Facebook? Read More
deCODE and Radboud University discover common variants in the human genome conferring risk of bladder cancer
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.
Not all genetic tests are created equal

Here are a few thoughts on Nic Fleming’s piece on personal genome scans, of which one was our own, deCODEme:
Our genomes are all remarkably similar. And so it is the differences that are most interesting and important, and that make us who we are.
The same can be said of genetic testing services. We at deCODE were not at all surprised that Mr. Fleming found that he got some varying results from the three genome scans that he tried. Indeed we would be surprised (and more than a little dismayed) if he hadn’t. Analyzing the genome - accurately detecting which genetic markers individuals have at specific points in the genome, and correlating these variations with risk of a range of common diseases - has been our bread and butter for well over a decade.

How much did Boonsri Dickinson learn from her home DNA test?
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.
