AF Symposium 2017
World-Wide Studies on Genetic A-Fib
Dr. Patrick Ellinor of Massachusetts General Hospital, Boston MA, updated everyone on the world-wide effort to identify the genetic basis of A-Fib.
What are the genetic variants associated with A-Fib? In previous research Dr. Ellinor showed, among other findings, that A-Fib is inheritable and that there is a 40% increased risk of developing A-Fib if a relative has it. (See my earlier report: Genetics of A-Fib 2012 AF Symposium.)
World-Wide Effort to Study A-Fib Genetics and Genome Sequencing
The biggest news is that A-Fib genetic research is increasing exponentially. The AFGen Consortium website lists 37 different studies and world-wide institutions studying A-Fib genetics with over 70,000 cases. Within the next 10 years, Dr. Ellinor and his colleagues hope to identify over 100 different genetic loci for A-Fib.
A-Fib Genetic “Fingerprint” May Help Identify Those at Risk of Stroke
Dr. Ellinor reported that using a genetic “fingerprint” of A-Fib helps to identify those patients at the greatest risk of a stroke. While still a research tool, this approach could be used to identify those patients at risk for either developing A-Fib or a stroke.
A-Fib genetic research and genome sequencing could someday identify the pathways and potential therapeutic targets of A-Fib.
In the future, genetic research may refine stroke risk models such as CHA2DS2-VASc and HAS-BLED to better target who may actually need anticoagulants and who can safely take them.
Participate in A-Fib Genetic Studies
If you and at least 3 other members of your family have A-Fib, you can become involved in this potentially very important research. Contact the studies at Mass. General Hospital or Vanderbilt University.
