My son was just diagnosed with Crohn's disease and I was wondering about the genetic links. I had found out several years ago when I was pregnant that I carry the gene for Cystic Fibrosis. We tested my husband and he does not carry the gene so therefore, our children would not get the disease. However, I researched the subject on the internet and found out that there is a known link between Cystic Fibrosis and Crohn's disease and that patients with Cystic Fibrosis have a 17 times higher incidence of Crohn's disease. A drug called Infliximab helps to treat both the colonic lesions and the Cystic Fibrosis. Has anyone else heard about this?
