A sibling of a patient with Crohn's disease has a 30-fold increased risk of developing the disease compared with the general population. The largest study ever to look at why an expensive and commonly used group of drugs fails some patients with Crohn's disease has identified a genetic marker which could individualise drug treatment. One study, for example, found that more than 18.5% of people with Crohn's disease also have celiac disease. When many people think of Jewish genetic disorders, Tay-Sachs disease comes to mind.

Crohn's disease (CD) was first recognized as a distinct entity 75 years ago, and although significant progress has been achieved in demystifying aspects of its molecular pathogenesis, diagnosis, and treatment, its etiological origins remain scarce; at present, CD is considered a result of multifactorial interplay between genetic, immune-related, environmental, and infectious triggers that . We aimed to assess whether increased serum anti-microbial antibody response in asymptomatic first-degree relatives (FDRs) of CD patients is an independent risk factor for future CD development.

When given proper medical care, most people who have Crohn's disease are able to lead long and productive lives. Immune System Response: In people with inflammatory bowel disease (IBD)—like Crohn's—the immune system responds inappropriately to the gastrointestinal tract, resulting in inflammation. Crohn's disease is usually diagnosed in people between the ages of 20 - 30. Many of the major genes related to Crohn disease, including NOD2, ATG16L1, IL23R, and IRGM, are involved in immune system function.
