Breast cancer gene tests explained
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%.

A hypocondriac meets deCODEme and comes out eating apples
By Edward Weinman
With a simple swab from the inside of your cheek, deCODE genetics can scan your DNA, map your markers and assess your risk of developing 29 common diseases. Edward Weinman, self-described hypochondriac, wonders if he should look too closely at his possible future.
Genetic test helps to detect prostate cancer
Chief scientific officer of deCODE, Jeff Gulcher (48) takes a deCODEme scan that indicates he has a very high risk bracket for prostate cancer. Taking his results to a urologist may have saved his life.
Rick Weiss of the Washington Post reports:
Jeffrey Gulcher had no reason to think much about prostate cancer. He was just 48, and the disease typically strikes later in life. Even the most cautious medical groups agree that most men need not begin annual prostate screenings until age 50.
But Gulcher happens to be the chief scientific officer of deCODE Genetics — one of several companies that, amid some controversy, have begun offering direct-to-consumer DNA tests that can help people predict which diseases they are likely to get. So in April, he spat into a test tube and, without giving the matter much thought, sent the sample in for analysis by his own company.
He was in for a shock.
