deCODE You

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.

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.
