deCODE Finds Genetic Factors Impacting Key Clinical Measurements of Heart Activity and Disease Risk

REYKJAVIK, Iceland, January 10 /PRNewswire-FirstCall/ -- - Novel
SNPs Modulate ECG Measurements Including Heart Rate, Two are Also
Risk Factors for Atrial Fibrillation and Will be Integrated Into
deCODE AF(TM) Test 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 at
http://www.nature.com/ng, and will appear in an upcoming print
addition of the journal. The deCODE team began by correlating ECG
measurements with genome-wide SNP data from more than 40,000
Icelandic participants in its gene discovery program. This search
identified one novel SNP influencing heart rate and four each
linked to PR interval and QRS duration, measurements of how quickly
the electrical impulses that cause the heart muscles to pump
achieve their purpose. Intriguingly, SNPs on chromosome 3 linked to
both longer PR interval and QRS duration are in the gene encoding
SCN10A, a sodium channel that has never before been linked to heart
activity. Individuals with the same variants were also more likely
to have been fitted with a pacemaker. A follow-on analysis of all
of the novel SNPs in Icelandic and Norwegian heart patients and
controls demonstrated the association of two of the SNPs linked to
PR interval to risk of AF, and another SNP to increased risk of
advanced atrioventricular block. Two other papers published today
in the same journal provide further validation of some of the
deCODE findings. "Over the past two years, we have discovered major
genetic risk factors for heart disease and stroke and introduced
tests for these risk factors into clinical practice. We are
building the power of these tests through our ongoing discovery
work, and today's findings demonstrate again the fruitfulness of
using intermediate risk factors and clinical measurements as entry
points for finding risk factors for disease. Our population
resources enable us to do so efficiently and with exciting results.
These latest findings will be incorporated into our deCODE AF test
and deCODEme scans, and certain of these discoveries may also
provide opportunities for outlicensing for therapeutic
development," said Kari Stefansson, CEO of deCODE. About deCODE
deCODE is a global leader in analysing and understanding the human
genome. deCODE has identified key variations in the sequence of the
genome conferring increased risk of major public health challenges
from cardiovascular disease to cancer, and employs its gene
discovery engine to develop DNA-based tests to assess individual
risk of common diseases; to license its tests and intellectual
property to partners; and to provide comprehensive, leading- edge
contract services to companies and research institutions around the
globe. Through its CLIA- and CAP-certified laboratory deCODE offers
DNA-based tests for gauging risk and empowering prevention of
common diseases, including deCODE T2(TM) for type 2 diabetes;
deCODE AF(TM) for atrial fibrillation and stroke; deCODE MI(TM) for
heart attack; deCODE ProstateCancer(TM) for prostate cancer; deCODE
Glaucoma(TM) for a major type of glaucoma; and deCODE BreastCancer,
for the common forms of breast cancer. Through its pioneering
personal genome analysis service deCODEme(TM), deCODE enables
individuals to better understand their risk of dozens of common
diseases and to learn about their ancestry and other traits. Visit
