• Welcome to Crohn's Forum, a support group for people with all forms of IBD. While this community is not a substitute for doctor's advice and we cannot treat or diagnose, we find being able to communicate with others who have IBD is invaluable as we navigate our struggles and celebrate our successes. We invite you to join us.

Common genetic thread found

Poring over genetic information from more than 86,000 people of European ancestry (50,000+ subjects, 35,000+ controls), researchers have discovered that five inflammatory diseases, ankylosing spondylitis, Crohn's disease, ulcerative colitis, psoriasis, and primary sclerosing cholangitis, share a common genetic basis. That is, variations in these sets of genes predispose people to development of any or a combination of these diseases.

Though they've identified hundreds of genes, here's the five with the highest probability:

1) rs3184504 / SH2B3 (prob. 0.978) This gene encodes a member of the SH2B adaptor family of proteins, which are involved in a range of signaling activities by growth factor and cytokine receptors. The encoded protein is a key negative regulator of cytokine signaling and plays a critical role in hematopoiesis. Mutations in this gene have been associated with susceptibility to celiac disease type 13 and susceptibility to insulin-dependent diabetes mellitus. Alternatively spliced transcript variants encoding different isoforms have been found for this gene.

2) rs367569 / TNP2 (prob. 0.961)

3) rs2266961 / UBE2L3 (prob. 0.963)

4) rs6058869 / DNMT3B (prob. 0.953)

5) rs61839660 / IL2RA (prob. 0.943) Receptor for interleukin-2. The receptor is involved in the regulation of immune tolerance by controlling regulatory T cells (TREGs) activity. TREGs suppress the activation and expansion of autoreactive T cells.
