Genetics research by the IBDGC is conducted in conjunction with the 6 Genetics Research Centers. These projects employ a variety of approaches to identify genetic variation that contribute to disease susceptibility; for example, candidate gene and pathway analyses. Additionally, Consortium projects aim to build risk models through understanding of genetic influence on variations in phenotypes and gene-environment interactions. The Consortium Analytic team is lead by Mark J. Daly (Broad).
A selection of recent publications are presented below.
