ISGC

The International Stroke Genetics Consortium (ISGC) was created in April 2007 by a group of 16 investigators from Europe and North America interested in stroke genetics research. Since then, the ISGC has held one international workshop every six months, hosted by ISGC members from around the world, and has become an international, multidisciplinary network of more than 200 stroke genetics investigators, representing over 38 countries in 6 continents.

Working Groups

Among the goals of this committee are to increase efficiency of analyses and create an expert community to aid in solving problems faced by less experienced ISGC members.

Our mission is to decipher genetic determinants, both single gene and complex inheritance of early-onset stroke and cerebrovascular disease and search for the pathways through which they alter stroke susceptibility. We expect that this effort will lead to better treatments for Mendelian forms of stroke and will identify novel biological mechanisms that are also relevant to older-onset stroke.

This group undertakes harmonization of image characterization/measurement approaches across ISGC centers and contributes images to the ISGC-NINDS stroke imaging repository at MGH.

Formed in the fall of 2012, this group is responsible for harmonizing stroke outcome measures across member sites.

This working group is devoted to expanding ISGC participation to underrepresented regions and populations.

The goal of this group is uniting researchers whose goal is to use genetic and genomic tools to improve understanding of the pathophysiologic basis of cerebrovascular disease.
