What about Arthiris? There's some link between UC and RA. I get both flare up at the same time, and I use the same medication (Azathioprine) to keep both in remission.
It sounds like ETS2 for sure has implications for spondylitis, although unclear to me whether it's a direct link or just because a lot of people who have IBD also have spondylitis. If it's the former, then my guess would be that there's a link to other types of arthritis as well.
