New Genetic Discovery May Explain Why Some People With Crohn’s Disease Suffer More

While the cause of Crohn’s is not totally clear, researchers have established that the presence of certain genes ? more than 170 genes fall into this category ? along with the presence of some types of gut bacteria, are linked to a person’s risk of developing the disease. Typically, the more of these 170-plus Crohn’s “risk” genes a person has, the more likely they are to develop Crohn’s.
