Evidence for significant overlap between common risk variants for Crohn's disease and ankylosing spondylitis.
<h4>Background</h4>A multicenter genome-wide association scan for Crohn's Disease (CD) has recently reported 40 CD susceptibility loci, including 29 novel ones (19 significant and 10 putative). To gain insight into the genetic overlap between CD and ankylosing spondylitis (AS), thes...
